• Speckled green fruitworm

  The adult is grayish beige with two purplish gray spots on its wings and a hairy thorax. The eggs are laid on the upper surface of the leaves.

• Prionus borers

  Adults are robust, broad, somewhat flattened blackish to reddish brown beetles with antennae roughly half the length of their bodies.

• Bacterial spot

  Bacterial spot appears on apricot, peach, nectarine, plum and prune.

• Verticillium wilt

  Leaves wilted or browned on one or several branches, often remaining attached; the rest of the tree appears healthy. Young trees are often killed by infection.

• Apple red bug

  Adult has head and thorax bright red in color with brown wings.

• 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.

• Stink bugs

  The adult has an oval shield-shaped body, grayish or brownish in color; a spur is present on each side of its thorax. Eggs, grouped in masses of 20 to 30, are in the shape of small barrels. They are gray, cream or gold-colored, decorated by a ring of small hairs.

• Green stink bug

  Stink bug adults have a broad, flattened, shield-shaped body and a narrow head. The green stink bug is uniformly grass-green.

• Roundheaded appletree borer

  Adult has a hard, elongated body, with white and brown longitudinal stripes and long antennae. The larva is a fleshy, cream-colored legless grub with a dark brown head, blackish mandibles.

• Green fruitworm

  Immature larvae of the green fruitworm (GFW) feed on flower buds and new foliage.

• Spirea aphid

  The eggs are oval and shiny black. The adults and nymphs are olive-green with brown-black legs, antennae, and cornicles. They live in colonies.

• Minute pirate bug

  Adults are very similar in size to the mullein plant bug (Campylomma varbasci), but their head is narrower and their wings are colored contrasting white and black.

• 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.

• Eastern tent caterpillar

  The adult is reddish brown with two white, 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 yellow line on their back.

• Black cherry aphid

  Adults and nymphs are shiny black soft-bodied insects; adults may or may not have wings. Nymphs are smaller, but generally similar in appearance to the adults.

• 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.

• Click beetles

  The click beetle is dark-colored its body is hard and elongated it has a characteristic pair of spurs and sometimes colorful markings on its thorax.

• Cherry leaf spot

  Lesions begin as small, circular red to purplish spots on the upper leaf surface. Spots enlarge as they grow older, typically coalescing and turning brown. Lesion centers may eventually drop out to give the leaf a "shot-hole" appearance, particularly on plum.

• White peach scale

  Adult female is creamy-white to reddish orange, and covered by a round waxy scale that is grayish to brownish white. Adult males are tiny yellow 2-winged insects, and nymphs are oval and white to orange.

• Spotted wing Drosophila

  Spotted wing Drosophila can be distinguished from other vinegar flies by spots on the wings of male flies, and by the ovipositor on female flies.
