Special Note:

Those of us who live in the Southwest, especially Arizona, know of the insect problems such as Scorpions, & Tarantulas. Then there are other annoying insects such as Ants!

The most effective poison we have found is any poison that contains Bifenthrin 7.9 %. Bifenthrin 7.9 % seems to be the strongest % sold on the matrket.

We have found that Bifen IT is the least expensive poison on the market that contains Bifenthrin 7.9 %.

We have referred several of our neighbors to a company that is online that sells Bifen IT. They have tried it, and they LOVE Bifen IT. No More Scorpions !!! No More Tarantulas !!!

One neighbor used to go out often at night with a black light to find scorpions. He would find about 20 in an hour. Now, he says he can't find any. That is because he sprays his whole property with Bifen IT.

He says "the price is cheap, and it works for about 3 months. so, it is a cheap way to keep my whole property clear of harmful insects!" "But, if you have heavy rain, you may have to repeat the spraying."

Well, We've followed his advice and we spray our whole property now, and NO MORE SCORPIONS!

By the way, when we first used Bifen IT, we would find a dead scorpion on occasion. But, they had only walked about 4 inches onto the area we sprayed, and they died! The sprayed area would last for about 3 months.

Bifen IT, is a great insecticide for the money !!!

The company online that we have referred our neighbors to is

WE have placed links on our web pages to We have found them to be an excellent company to do business with.

Fruit Tree Pests In Arizona.

Here Are Our Descriptions Of Some Of The More Common Fruit Tree Pests In Arizona.
No Attempt Here Is Made To Show All Of Them!!
Photos & Descriptions Courtesy Of: Wikipedia, the free encyclopedia.

Aphid; (Wingless Potato) , Macrosiphum euphorbiae. Under Eggplant Leaf, & Inside Eggplant Flower.

Wingless Potato Aphid , Macrosiphum euphorbiae. Wingless Potato Aphid , Macrosiphum euphorbiae. The Wingless Potato Aphid , Macrosiphum euphorbiae is a sap-sucking pest insect in the family Aphididae. It infests potatoes and a number of other commercially important crops.

The Wingless Potato Aphid originated in North America but it has spread to the temperate parts of Europe and Asia and is found in all areas of the world where potatoes are grown.

The wingless female potato aphid is green or sometimes pink, often with a darker dorsal stripe. It has a pear-shaped body reaching about four millimetres long. longer than the body. The winged female has a uniform darker colored body and appendages and has a green abdomen. The nymphs look like miniature versions of the adults and they go through several moults in the course of about ten days.

The female potato aphids usually overwinter on weeds & they usually emerge in April and begin feeding on perennial weeds, preferring plants in the Chenopodiaceae family. Then in about May or early June, they migrate to potato, cabbage, tomato and others crops where they feed on shoots, the lower side of leaves, buds and flowers, often on the lower parts of the plant. They are highly polyphagous, feeding on over two hundred species in more than twenty plant families, but their preference is for plants in the Solanaceae family.

While in some cases, high temperatures or heavy rainfall may reduce infestations and the numbers are naturally controlled by predators, parasites and pathogens. If numbers of aphids are sufficiently high, chemical control should be attempted using insecticidal soaps or poisons. This is not always effective because the aphids usually congregate on the underside of lower leaves where they are difficult to reach with sprays.

A number of virus diseases are spread by Macrosiphum euphorbiae. These include lettuce mosaic virus, bearded iris mosaic virus, narcissus yellow stripe virus, tulip breaking virus, potato leaf roll virus, potato virus Y, beet mild yellowing virus and beet yellows virus.

Codling Moth, Cydia pomonella.

Codling Moth, Cydia pomonella. The codling moth (Cydia pomonella) is a member of the Lepidopteran family Tortricidae. They are known as an agricultural pest, their larva being the common apple worm or maggot. It is native to Europe and was introduced to North America, where it has become one of the regular pests of apple orchards. It is found almost worldwide. It also attacks pears, walnuts, and other tree fruits.

This larva is the infamous "worm in the apple" of cartoon and vernacular fame; it is not related to the earthworm.

The codling moth is greyish with light grey and copper stripes on its wings, and has an average wingspan of 17 mm. The females lay eggs on fruit or leaves and the black-headed yellow larvae attack the fruit immediately upon hatching. Each larva burrows into the fruit, eats for around three weeks, then leaves the fruit to overwinter and pupate elsewhere. Most nourishment is obtained by feeding on the proteinaceous seeds.

European Corn Borer, Ostrinia nubilalis.

European Corn Borer, Ostrinia nubilalis. European Corn Borer, Ostrinia nubilalis. The European Corn Borer, Ostrinia nubilalis, also known as the European high-flyer, is not a problem to fruit tree, but it is a pest of grain, such as corn, particularly maize. The insect is native to Europe, originally infesting varieties of millet, including broom corn. But, European corn borer is known to feed on 250 different kinds of plants, some of which include: corn, especially sweet corn, chrysanthemum, dahlia, gladiolus, eggplant, pepper, beet, bean, potato, tomato, oat, soybean, and many kinds of weeds.

The European corn borer was first reported in North America in 1917 in Massachusetts, but was probably introduced from Europe several years earlier. Since its initial discovery in the Americas, the insect has spread into Canada and westward across the United States to the Rocky Mountains. Arizona has a quarantine in effect for this pest.

The larvae, during the borer stage, can vary in length from ¾ to 1 inch and have a gray to creamy white color. The larvae eat leaves and tunnel into all parts of the stalks and ears; the major damage to sweet corn is to the ears. The tunneling impairs the growth of the plant and causes the plants to fall over. Biological control agents of corn borers include the hymenopteran parasitoid Trichogramma spp., the fungus Beauveria bassiana and the protoza Nosema pyrausta.

The moths appear in June, and are about one inch long with a one inch wingspan. The female moth is light yellowish-brown with dark, irregular, wavy bands across the wings. The male is slightly smaller and darker in coloration. The tip of its abdomen protrudes beyond its closed wings. The fully-grown larva is three-quarters to one inch in length. This borer is usually flesh-colored, but may range from light gray to faint pink, with conspicuous small, round, brown spots on each segment.

Female corn borer moths lay clusters of eggs on corn leaves, usually on the underside. The egg masses, or clusters, are laid in an overlapping configuration and are whitish-yellow in color. As the larvae develop inside their eggs, the eggs become more and more transparent and the immature caterpillar black heads are eventually visible. The caterpillars hatch by chewing their way out of the eggs.

(Leaf - Footed Bugs): Female Giant Agave Bug, Acanthocephala thomasi.

Female Giant Agave Bug, Acanthocephala thomasi.

The Giant Agave Bug, Acanthocephala thomasi which is considered a Leaf - Footed Bug, is a member of the family, Hemiptera, the true bug family, of the order Coreidae.

Adult leaf-footed bugs are so named because of the flattened tibia on the rear legs (the tibia is the leg section between the foot and the section that is attached to the body).

The adult body can be a greenish gray to black, about ¾" inch-long, with upwardly pointed structures on what we would think of as the shoulders. They are hard bodied which makes them somewhat difficult to control. Juveniles (nymphs) are smaller and often mostly black with a red spot on their back.

The leaf-footed bug often attacks ripening fruit crops, such as peaches or nectarines, and causes discolored depressions or blemishes called cat-faces. These scars can cause undersized fruit or premature drop. Sometimes, you may notice clear sap to oozing out of the wounded areas on the fruit. These are where puncture wounds were made by the Giant Agave Bug's long, piercing mouthparts.

Leaf-footed bugs also attack pecan nuts causing black pit in the kernels. When fruit crops are not available, they can be found eating the flowers and fruit of crepe myrtle, privet, and roses.

Detecting and diagnosing these pests can be difficult because often they are not seen on the fruit or nut tree. They may be on a neighboring plant resting during the day, then travel to feed on the fruit or nut tree at night or in the early morning.

Peach Tree Borer, Synanthedon exitiosa. Male - Larva - Root Damage.

Peach Tree Borer Male, Synanthedon exitiosa. Peach Tree Borer Larva, Synanthedon exitiosa. Peach Tree Borer Damage, Synanthedon exitiosa. The Peachtree Borer (Synanthedon exitiosa) is a moth of the Sesiidae family. It is found in eastern and central North America. The peachtree borer and the lesser peachtree borer, Synanthedon pictipes, account for more damage to peach trees than all other insect pest combined. The peachtree borer can damage the tree in two ways: girdling and inducing plant pathogens to invade the weakened tree.

Peachtree borers are native to the United States. They are found throughout the United States and Canada.

Peachtree borer larvae vary from about 1.25 to 3.5 cm in length and they are white with a brown head.

The adult moths are wasp-like in appearance.

Adult females are dark, metallic blue in color with opaque fore wings and clear hind wings. The wingspan is approximately 3.5 cm. The abdomen is encircled with one or two yellow bands on the fourth and fifth or only the fourth abdominal segment.

The adult male is slightly slightly smaller and more slender than the female. Both pair of wings are clear. His wingspan is slightly smaller and measures about 2.25 cm. He also has a number of narrow yellow bands on the abdomen.

The moths are on wing flying from about May to September.

The larvae feed on Prunus & the Rosaceae species. which include peach, cherry, plum, prune, nectarine, apricot, and ornamental shrubs. They prefer healthy plants. They can become a pests in orchards.

Peach Twig Borer, Anarsia lineatella.

Peach Twig Borer, Anarsia lineatella. The Peach Twig Borer (Anarsia lineatella) is a moth of the Gelechiidae family. It is very commonly found in Europe, but it was introduced into California in the 1880's.

It's wingspan is about 11–14 mm. The moths are flying from about June through August depending upon their location.

It's larvae feed on plants of the Prunus species, including peach, apricot, nectarine, almond , plum, & prune. In California, the Peach Twig Borer is a major pest of the local almond plantations.

An excellent resource of information about the Peach Twig Borer is "Peach Twig Borer" from the Utah State University Extension and Utah Plant Pest Diagnostic Laboratory, by Diane Alston, Entomology Specialist & Marion Murray, IPM Project Leader.

Pear & Cherry Slug, Caliroa cerasi. -------- Adult Sawfly, Caliroa cerasi

Pear & Cherry Slug, Caliroa cerasi. Sawfly, Caliroa cerasi. The cherry slug or pear slug is the larva of the sawfly, Caliroa cerasi. They are not slugs but are a kind of insect of the Family Tenthredinidae. The cherry slug is an important pest that eats leaves of cherry, pear, and plum trees, leaving behind a skeleton of veins. The larvae cover themselves in green slime, making themselves unpalatable to predators. When the larvae are fully grown, they drop off the tree on the ground and pupate underground. The adult sawfly emerges from the pupal case and climbs from the soil to mate and lays eggs on the leaves of the host plant, completing the lifecycle.

Other sources dispute the notion that the females climb the tree to lay their eggs, claiming instead that they fly to the tree. This is an important detail in regards to their control in horticultural circumstances where glues are used to control climbing pests.

Pear Blister Mite, Phytoptus pyri. Effect On Leaf & Pear Blister Mites.

Pear Blister Mite, Phytoptus pyri. Pear Blister Mite, Phytoptus pyri. Pear Blister Mites are very tiny eriophyid mites that feed on the surface cells of the undersides of leaves. These feeding wounds break open & the mites further invade the damaged areas of the leaves.

The upper leaf surface opposite the original leaf injury takes on a blistered appearance.

Continued feeding by the mite causes the leaf injuries to coalesce producing brown scabby patches upon the leaves. The leaf injuries tend to be concentrated around the midrib of the leaf.

The adult females usually spend the winter under bud scales and other protected areas upon the twigs. Then, they move to the newly expanding leaves, soon after bud break, and suck the sap of cells on the lower leaf surface. Then the feeding sites rupture and the females lay their eggs within the wounds; which further expands the damaged site. Individual wounds typically get about 3 mm in diameter and later dry out if they are colonized; any non colonized wounds remain green or reddish in color. There are multiple generations of mites per season, each taking about a month to complete it's life cycle. New individuasl from these parent mites can start new injuries again, throughout the midsummer.

The damage to the plant is rarely sufficient to warrant any control action by the grower. Insecticides with activity against eriophyid mites (e.g., carbaryl) can be very effective. Dormant season applications of horticultural oils will kill the overwintering females.

Plum Curculio, Conotrachelus nenuphar.

Plum Curculio, Conotrachelus nenuphar. The plum curculio (Conotrachelus nenuphar) is a true weevil native to the regions east of the Rocky Mountains in the United States and Canada. It is notorious for destroying fruits if left uncontrolled.

The female Plum Curculio uses a number of fruit hosts to lay her eggs, including plums, peaches, apples, pears, and other stone fruits.

After the female has chosen a suitable fruit, she will build her egg chamber under the fruit skin to receive the egg. She then will turn around and place the egg into the cavity in the fruit. Next, she slices a curved slit underneath the fruit cavity to leave the egg in a flap of flesh. Eggs that do not hatch are killed from the pressure caused by the normal growth of the hosting fruit. This results in a crescent-shaped scar which is visible on the outside of the fruits skin.

Plum curculio larva are about 6 to 9 mm long when fully grown. After growing and turning into the pupal stage, it measuring about 5 to 7 mm, all adult characteristics are visible in this stage prior to transformation.

The newly emerged adult plum curculio is about 4 to 6 mm long, with a small, rough snout, colored a blackish, gray, and with brown specks. The adult has four pairs of ridges covering the wings; however, because of the middle humps, it only appears to have two ridges.

The plum curculio can be found in apple, nectarine, plum, cherry, peach, apricot, pear and quince trees & fruit. It may also survive on wild plum, hawthorn, and crabapple. It is found most commonly in the areas east of the Rocky Mountains and in eastern Canada.

The plum curculio beetles are most active during the spring time when the weather is warm, damp, and cloudy. They are often seen in heavy leafed trees.

Plum curculio beetles can cause irreparable damage to a fruit harvest. In badly damaged fruit, one can identify large scars and bumps due to feeding. Most fruit internally damaged through burrowing into the fruit often drop prematurely.

Even so, we often see damaged fruit, caused by the plum curculio, in grocery stores in Arizona.

San Jose Scale, Quadraspidiotus periciosus.

San Jose Scale, Quadraspidiotus periciosus. San Jose scale (Quadraspidiotus perniciosus) is a hemipterous insect and It is an agricultural pest as it causes damage and crop loss to many fruit crops.

San Jose scale originated in Siberia, north east China and the northern part of the Korean peninsula. It has spread to every continent except Antarctica and is now considered a major pest of fruit trees.

The San Jose Scale derives its popular name from San Jose, California where Comstock discovered and named it in 1881. It has been considered the most pernicious scale insect in the United States. It was probably introduced at San Jose about 1870 on trees imported from China by James Lick. By 1890 it had spread over the greater part of California, but was not recognized east of the Rocky Mountains until August, 1893, when it was found by Howard on a pear received from Charlottesville, Virginia. Soon afterward it was discovered that infested stock had been brought from California in about 1887 or 1888 by two New Jersey nurseries and distributed widely. By 1895 San Jose Scale had become established in many nurseries and orchards in the majority of the Eastern United States. Marlatt made entomological investigations in China, Japan, and Java in 1901-02. He introduced the ladybird to the United States in order to control the San Jose scale.

The body of adult female is yellow and is covered with a rounded dark gray scale up to two millimetres in diameter. Over the course of two months, yellow crawlers are born viviparously and emerge from the back of the test at the rate of two or three a day. In bad weather they gather under their mother's scale. The crawlers disperse to other parts of the plant and start feeding. They moult after about ten days and begin to lose their eyes, legs and antennae. The adult female appears after the next moult and the scale develops, incorporating the larval exuviae. The development of the male involves three moults. The male nymph is more elongate than the female and the adult male is orange coloured and has wings. It lives only for a few hours.

The San Jose Scale is found in both temperate and subtropical climates. It infests about two hundred different species of host plants, mostly deciduous trees and bushes. It is found on the trunks, branches, twigs, leaves and fruits of the plant. Females predominate on the leaf stalks and fruit while males predominate on the leaves. There may be several generations each year in warm climates but in cooler regions there is a single generation. The first and second instars may overwinter in cracks in the bark and the hibernating nymphs can survive temperatures as low as -42°C. The emergence of the nymphs in the spring coincides with bud burst.

Shield Bugs: (Bordered Plant Bug), Largus succinctus.

Bordered Plant Bug, Largus succinctus

Generally speaking the Bordered Plant Bug Largus succinctus does not cause a problem to fruit or vegetable gardens but, they have been reported to do so when they are present in large numbers. One gardener has reported that "They have eaten corn, tomato, squash and just about anything else. I put a couple blue berries in pots that had blueberries and they ate the fruit".

They are in oak, shrub areas and have been reported to eat from those trees.

Stink Bugs: (Brown Marmorated Stink Bug), Halyomorpha halys.

Brown Marmorated Stink Bug, Halyomorpha halys. There are 2,000 species of stink bugs in the world, with over 225 in North America. Some are considered bad for your garden or orchard and some are considered good!

Halyomorpha halys, the brown marmorated stink bug, or simply the stink bug, is an insect in the family Pentatomidae, and it is native to China, Japan, Korea and Taiwan. It was accidentally introduced into the United States, with the first specimen being collected in September 1998. The brown marmorated stink bug is considered to be an agricultural pest, and by 2010 - 2011 has become a season-long pest in the U.S. orchards.

The adults are approximately 1.7 centimetres (0.67 in) long and about as wide, forming the "shield" shape characteristic of other stink bugs. They are various shades of brown on both the top and undersides, with gray, off-white, black, copper, and blueish markings. Markings unique to this species include alternating light bands on the antennae and alternating dark bands on the thin outer edge of the wings. The legs are brown with faint white mottling or banding. The stink glands are located on the underside of the thorax, between the first and second pair of legs, and on the dorsal surface of the abdomen.

The Brown Marmorated Stink Bug is an agricultural pest that can cause widespread damage to fruit and vegetable crops. In Japan it is a pest to soybean and fruit crops. In the U.S., the brown marmorated stink bug feeds, beginning in late May or early June, on a wide range of fruits, vegetables, and other host plants including peaches, apples, green beans, soybeans, cherry, raspberries, and pears. It is a sucking insect, a "true bug", that uses its proboscis to pierce the host plant in order to feed. This feeding results, in part, in the formation of dimpled or necrotic areas on the outer surface of fruits, causing leaf stippling, seed loss, and the possible transmission of plant pathogens.

It also is known to invade peoples homes in the fall. The bug survives the winter as an adult by entering houses and structures when autumn evenings become colder. Once inside the house, they go into a state of hibernation. They wait for winter to pass, but often the warmth inside the house causes them to become active.

The odor from the stinkbug smells like cilantro.

The stinkbug's ability to emit an odor through holes in its abdomen is a defense mechanism meant to prevent it from being eaten by birds and lizards. However, simply handling the bug, injuring it, or attempting to move it can trigger it to release the odor.

The brown marmorated stink bug was accidentally introduced into the United States from China or Japan. It is believed to have "hitched a ride" as a stowaway in packing crates. As of May 2011 it had spread to 33 U.S. states.

It is often confused with the species; Brochymena, and Euschistus. It is similar in appearance to other native species of shield bug including Acrosternum, Euschistus, and Podisus.

The stinkbug's pierce a fruit’s outer surface and suck out juices while injecting saliva. The suction and saliva create a dimpling of the fruit’s surface, and rotting and corking of the flesh underneath.

The fruit is not able to be sold, because of appearance, but the dimpled area is not poisonous to humans.

The stinkbug's attack several types of plants — including soy beans, lima beans, and sweet corn. However, fruit show their damage more quickly and orchard owners monitor for damage more closely.

Stink Bugs: (Brochymena Stink Bug), Brochymena sulcatus.

Brochymena  Stink Bug, Brochymena sulcatus. Rough Stink Bugs are not harmful to your garden since these beneficial predators prey on caterpillars, the plant eating larvae of beetles, adult beetles, aphids, and other soft-bodied insects with their piercing and sucking mouthparts. You will find them on landscape trees and fruit trees in home landscape.

The Rough Stink Bug is a member of the Pentatomidae family. The Rough Stink Bug is capable of producing teeming amounts of foul-smelling fluid it discharges when disturbed. Both adults and nymphs possess large stink glands on their undersurface, which open through conspicuous slits.

Rough Stink Bugs are very well-camouflaged and closely resemble the color and texture of tree bark on which it lives. When you first notice them, you might think that they are an insect pest!

The adult stage is about ½ inch long. The Rough Stink Bug has an elongated head with antennae located far in front of their compound eyes.

Generally, beneficial species of stink bugs are distinctive from their plant feeding counterparts. Aside from their color and rough-textured appearance, there are two other ways to tell the difference. Predatory Rough Stink Bugs have spines projecting from the corners of their thorax, whereas plant feeders have rounded "shoulders." They also have short, thick beaks while plant feeders have long, slender mouthparts.

Stink Bugs: (Euschistus Stink Bug), Euschistus ictericus.

Euschistus Stink Bug, Euschistus ictericus. Euschistus ictericus is a North American species of shield bug. It lives in damp areas. It is NOT considered a pest to your garden or orchard!

E. ictericus grows to a length of 10.5–12 millimetres (0.41–0.47 in), and can be distinguished from other members of the "brown stink bugs" by the lack of black spots in the middle of the ventral side of the abdomen, and by the presence of black rings around the spiracles on the abdomen.

Stink Bugs: (Green Stink Bug), Acrosternum hilare.

Green Stink Bug, Acrosternum hilare.

The green stink bug or sometimes called, green soldier bug (Acrosternum hilare) is a stink bug belonging to the family Pentatomidae.

According to Dr. David Rider of North Dakota State University the generic name is wrong. The genus name Acrosternum should be restricted to a handful of Old World, small, pale green species that live in dry arid areas. The larger, brighter green species that live in both the Old and New Worlds should actually go by the generic name Chinavia, therefore this species should be called Chinavia hilaris.

The Green Stink Bug, Acrosternum hilare is found in orchards, gardens, woodlands and crop fields throughout North America, feeding with their needle-like mouthparts on the juices of a wide variety of plants from about May until the arrival of frost. Adults have a preference for eating the developing seeds of plants and thus become crop pests (ie..tomato, bean, pea, cotton, corn, soybean, eggplant). When no seeds are present, they will feed on the stems and foliage, thus damaging several fruit trees, such as the apple, cherry, peach, and orange.

The Green stink bug is typically bright green, with narrow yellow, orange, or reddish edges. It is a large, shield-shaped bug with an elongate, oval form and a length between about 13–18 mm. It can be differentiated from the species Nezara by its black outermost three antennal segments. Its anterolateral (= in front and away from the middle) pronotal margin is rather straight and not strongly arced such as in Acrosternum pennsylvanicum.

Both adults and nymphs have large stink glands on the underside of the thorax extending more than half-way to the edge of the metapleuron. They discharge large amounts of this foul-smelling liquid when disturbed.

The females attach their keg-shaped eggs on the underside of foliage in double rows of twelve eggs or more. The early instar nymphs are rather brightly colored and striped, turning green when approaching adulthood.

Squash Bug, Anasa tristis.

Adult. Squash Bug, Anasa tristis. Adults & Nymphs. Squash Bug, Anasa tristis. Eggs. Squash Bug, Anasa tristis.

The Squash Bug, Anasa tristis is a major pest of squashes, pumpkins, zucchinis, watermelons, cucumbers and cantaloupes. Squash bug feeding causes extensive damage to stems resulting in wilting, fruit discoloration and pre/postharvest spoilage.

Squash bugs transmit Cucurbit yellow vine disease now rapidly spreading through the west and Midwest.

There are few effective biological agents or cultural practices for controlling this highly destructive pest aside from insecticides to which the species has evolved resistance.

Use of resistant squash varieties, such as Butternut, Royal Acorn, and Sweet Cheese, Green-striped Cushaw, Pink Banana, and Black Zucchini helps to reduce bug problems. Handpicking and destroying bugs and their egg masses and trapping bugs under small boards placed under or near the vines and then destroying them are two popular control techniques, but they must be practiced with vigilance. The bugs can be destroyed by squashing them or drowning them in a container of soapy water. Egg masses should be crushed or burned. Some organic gardeners suggest interplanting with tansy, catnip, marigolds, bee balm, mint, and nasturtiums. Others suggest spraying with a kaolin clay crop protectant, but the effectiveness of such a treatment is not fully established.

Two Spotted Spider Mite, Tetranychus urticae. Individual & Colony.

Two Spotted Spider Mite, Tetranychus urticae. Two Spotted Spider Mite, Tetranychus urticae. Colony. The Tetranychus urticae (common names include red spider mite and twospotted spider mite) is one of many species of plant-feeding mites found in the dry environments across the world, including Arizona, and is generally considered a pest. It is the most widely known member of the family Tetranychidae or spider mites.

TheTetranychus urticae can feed on hundreds of plants, including most vegetables and food crops including peppers, tomatoes, potatoes, beans, corn, strawberries; and ornamentals such as roses.

It lays its eggs on the leaves, and it poses a threat to host plants by sucking cell contents from the leaves cell by cell, leaving tiny pale spots or scars where the green epidermal cells have been destroyed. Although the individual lesions are very small, attack by hundreds or thousands of spider mites can cause thousands of lesions and thus can significantly reduce the photosynthetic capability of plants. This can either weaken or kill the plants.

The spider mite's natural predator, Phytoseiulus persimilis, which is commonly used as a biological control method, is one of the many predatory mites, which prey mainly or exclusively on spider mites.

Wooly Apple Aphid, Erisoma lanigerum. Individual & Colony.

Wooly Apple Aphid, Erisoma lanigerum. Wooly Apple Aphid, Erisoma lanigerum. Root Damage. Woolly aphids (Erisoma lanigerum) are sucking insects that live on plant fluids, and they produce a filamentous waxy white covering which resembles cotton or wool on the plant. The adult aphids are winged and move on to new locations where they lay egg masses. The larvae often form large cottony masses on twigs, for protection from predators. They came to the USA from Japan.

The woolly apple aphid is the best known pest of fruit growers. There are numerous species of woolly aphids and sometimes they have only one host plant species. Often they alternate their generations of aphids on two specific hosts.

In flight they have been described as looking like "flying mice", and are given nicknames like "fluff bugs", "Don King bugs", "fairy flies", "Frederick Douglass flies" or "fuzz-butts". Due to their whimsical appearance, some parents tell children that they carry wishes, live in tulips, and much like fairies, are born every time you make a wish on a dandelion.

Woolly aphids eat by inserting their needle - like mouthparts into plant tissue to withdraw sap. They are able to feed on leaves, buds, bark, and even the roots of the plant. As a result of feeding on the sap, woolly aphids produce a sticky substance known as honeydew, which can lead to sooty mold on the plant.

Generally speaking, woolly aphids aren't much cause for alarm, but they can cause rather unsightly damage to plants, which is particularly a problem for growers of ornamentals. Symptoms of feeding include twisted and curled leaves, yellowed foliage, poor plant growth, low plant vigor, and branch dieback.

Further minor damage can be caused by the honeydew that woolly aphids secrete, which is difficult to remove. While the honeydew itself doesn't cause too much of a problem, the honeydew can cause sooty mold to grow, which can block some of the sunlight needed for photosynthesis.

Fruit Tree Pests:

In general there are many various pest organisms, primarily arthropods (insects and mites), diseases, weeds, and mammals that are associated with fruit production and they cause significant economic losses to commercial fruit growers.

Insect pests found in fruit orchards can be classified into two groups depending upon which plant part is attacked. Direct pests are those insects that feed upon fruits, while indirect pests are those that attack the leaves, trunk, and other parts of the tree.

Examples of direct pests of fruit are apple maggot, plum curculio, codling moth, and other internal fruit feeders.

Pests like spotted tentiform leafminer, aphids, and mites may affect fruit yield if they are present in large numbers, but since they do not directly injure the fruits, they are indirect pests.

Now, just when you think you have that idea in mind, there is another way to look at insect pests. That other idea is that insect pests can also be classified in terms of the seriousness of their infestation and effect on orchard economics.

Under that method there are three groups of pests - Major Pests are those that have the potential to cause major economic losses to the grower. Usually, most direct pests that feed on fruit are also considered major pests. For example, apple maggot, plum curculio, and codling moth constitute the major pests of apples in the upper Midwest, USA.

Indirect Pests usually do not feed on the fruit, and although their activities may limit fruit yield they are only considered minor pests.

A third category of pest insects are the Quarantine Pests . Quarantine pests are insects not known to be established in a given area. The flat scarlet mite and apple ermine moth are current examples of quarantine pests in the State of Minnesota.

Fruit Tree Diseases; General Comments:

Many diseases of apple are not restricted to one part of the tree. For example, apple scab attacks the fruit, leaves, and flowers. Powdery mildew can also infect many parts of the tree. Fire blight is a tree disease infecting leaves, shoots, limbs, and trunk, but it can infect fruit and root stock. The fungal disease complex known as sooty blotch and flyspeck is, however, restricted to the fruit.

Common peach and nectarine diseases are peach leaf curl, brown rot, scab, bacterial spot and powdery mildew.

Beneficial Insects:

Not all insects found in an fruit orchard or vegetable garden are pests. Many organisms benefit the grower by eating or parasitizing pests in the orchard or garden. These organisms are known as beneficials, natural enemies, or biological control agents. They may be native or introduced from other areas.

Beneficial natural enemies (insects and mites) that may occur in an orchard or garden could be classified as predators or parasitoids. Predators are those that attack, kill, and feed directly on a pest (prey). Examples of common orchard or garden predators are ladybeetles, flies, lacewings, wasps, bugs, ants, spiders, and predator mites. Parasitoids are insects that lay eggs on or in a pest (host). The developing larva lives and feeds on the host, parasitizing and eventually killing it. Examples include parasitic wasps such as the egg parasite, Trichogramma sp.

Bees are a different class of beneficial insects in the orchard or garden in that they benefit the grower by aiding pollination.

It is important that growers are able to recognize, identify, and conserve beneficials in their orchard or garden. Conservation of beneficial organisms is a basic tenet of an ecologically sound pest management strategy. Conservation or enhancement of beneficials can be achieved through judicious use of pesticides such as spraying 1. only when and where needed, 2. accurate timing of sprays, and 3. selecting pesticides that are least toxic to beneficials.

For Example: Many growers now place colonies of the Blue Orchard Mason bees in their orchards or gardens to pollinate their crops for maximum production.
