• Widestriped green fruitworm

  The adult has bluish or steel gray wings marked with inconspicuous mottled patches.

• Plum curculio

  The adult is mottled grayish black and brown. Its head is prolonged into a large but short snout that bears antennae. Each elytron has a series of humps with the 2nd and 3rd pairs separated by a clear transverse band.

• Forest tent caterpillar

  Adults are reddish brown with two brown, transverse-parallel bands. Masses of shiny black eggs are laid in a ring around twigs. Larvae have long silky hairs on their body and a row of elongated spots along the back.

• Pearleaf blister mite

  The adults are very small and cannot be seen without a 15X hand lens; the body is white and elongate oval in shape, like a tiny sausage.

• European apple sawfly

  The adult looks similar to a small, orange-brown wasp with the ventral side and legs orange in color. It has transparent wings with many veins. The egg, oval and translucent, is inserted into the receptacle of the flower.

• Spotted tentiform leafminer

  The adult is a tiny beige moth with heavily fringed wings striped with golden brown and white bands. Eggs are laid individually on the undersurface of the leaves.

• Perennial canker of stone fruit

  Small twig infections are usually found around winter-killed buds, leaf scars, and picking and pruning injuries. They appear as sunken discolored areas with alternating zonation lines and may ooze amber gum unless the twig is killed.

• Black peach aphid

  These smooth-looking, pear-shaped insects have long antennae and a pair of cornicles extending from the posterior end of the body.

• Codling moth

  The adult's forewings are striped with fine brown-gray lines and a distinctive bronze to brown-black oval spot at the tip. Eggs are laid on the leaves or fruit.

• Rose chafer

  The rose chafer is a light tan beetle with a darker brown head and long legs. It is about 12 mm long. There is one generation per year.

• Peach bark beetle

  Adult's body is brown with many punctures, from which arise yellowish hairs. The larva is a small, legless grub.

• Plum rust mite

  Plum rust mites (PRM) generally restrict their feeding to new foliage, causing these leaves to brown and roll upward longitudinally

• Apple sucker

  Adult resembles a miniature cicada, greenish yellow to yellow in color but sometimes containing reds or browns, with eyes pale green to reddish brown, and long slender antennae; wings are transparent and iridescent.

• American plum borer

  The adult is a light grayish brown moth with reddish brown forewings marked by wavy black and brown vertical bands about two-thirds the distance from the base.

• Buffalo treehopper

  The pale green adult exhibits a large thorax with two "horns" and a long posterior wedge-shaped body. The cream-colored eggs are laid in a groove on the tree bark, where they overwinter.

• Bacterial canker (blossom blast)

  Leaf scars, stomata, and areas of injury are the principal sites of infection. The most conspicuous symptoms are limb and trunk cankers, blossom blast, "dead bud", and leaf spotting; these symptoms may or may not occur together.

• Dogwood borer

  The adult is bluish black with yellow bands and has clear wings, resembling a wasp. Larva is creamy white to pink with a sclerotized reddish head.

• Southern blight

  Trees attacked by the fungus show a general decline. In the early phase of disease, a dense mat or web of white mycelium is evident at the base of the tree.

• Variegated leafroller

  Adult is grayish magenta with dark brown bands on the middle and end of the forewing. Larvae are pale green with yellowish green heads.

• Peachtree borer

  Adult is a clear-winged, metallic-blue moth that has one broad orange or two or more yellow bands across the abdomen; both sexes have more amber sheen on wings than lesser peachtree borer adults.
