• Apple red bug

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

• Peach leaf curl

  The pathogen infects young undeveloped tissue of leaves and fruit. Infection is most severe when cool conditions prevent rapid development of the foliage. Infected leaves curl and blister, leaving them severely deformed.

• 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.

• Bacterial spot

  On leaves, lesions are small, tan to brown in color, eventually becoming necrotic, and usually surrounded by a yellow halo. There are often numerous lesions on a leaf and they tend to be restricted to areas between veins, which gives them an angular appearance.

• 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.

• 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.

• Japanese beetle

  Japanese beetles can be present from June through September. Japanese beetle adults are metallic green or greenish bronze with reddish wing covers and several white spots near the abdomen tip and along the sides. Larvae are larger C-shaped grubs that live in the soil.

• Prunus necrotic ringspot

  Individual branches or the entire tree shows delayed budbreak or foliation, stunted wavy leaves, and shortened blossom pedicels in spring. Leaves develop chlorotic spots, lines, or rings as they emerge.

• Phytophthora root, crown, and collar rot

  Crown and collar rot are often and mistakenly used interchangeably. Collar rot refers to infection that affects the bark tissue of the scion portion of the tree at or just below the soil line, whereas crown rot affects the bark tissue of the rootstock portion of the tree.

• Cherry leafminer

  The adult is a small, bronzy tan-colored moth, with a wavy darkish brown to black band at the outer third of the forewings.
