• Brown stink bug

  Stink bug adults have a broad, flattened, shield-shaped body and a narrow head. The brown stink bug is brown to grayish-brown and slightly speckled.

• Green June beetle

  The adult is velvet green dorsally with yellow-orange margins on the elytra. Ventrally it is a shiny metallic green mixed with orangish yellow. The larva is a large, C-shaped grub that lives in the soil and is not found in the trees.

• Mucor Rot

  Infected tissue appears light brown, soft, and watery. The infection usually develops at wound sites, at the calyx end, or at the stem end of the fruit.

• Pear slug (Pear sawfly)

  The adult looks similar to a small, black-bodied wasp with the ventral side and legs yellow in color. The larva is small, fleshy, dark green to orange, slug-like, and slime-covered, with the front part of the body enlarged.

• Nectria canker

  Cankers are often associated with nodes, often appearing as elliptical sunken areas. Sometimes callus production stops fungal invasion and cankers die by season's end.

• Apple maggot

  Adults are black flies with three or four white cross bands on the abdomen, a prominent white spot at the posterior end of the thorax, and the wings are marked with black bands in the shape of an "F".

• Red velvet mites

  Balaustium is a large, bright red mite with a tick-like shape and a dense velvet-like covering of dorsal setae.

• Mineola moth (Destructive pruneworm)

  Adult is a bluish gray moth that assumes a wedge shape when at rest. It has a transverse broad white stripe bordered by a smaller reddish brown stripe in the middle of the forewings a smaller set of similar bands occur near the posterior edge.

• Alternaria blotch

  The disease primarily affects the foliage, causing circular, necrotic lesions with a light brown interior that later become surrounded by a darker purplish halo.

• Apple leaf (curling) midge

  The adult is a tiny dark brown fly, and the larva is a yellow-white maggot with a reddish tinge.

• Dusky stink bug

  Stink bug adults have a broad, flattened, shield-shaped body and a narrow head. The dusky stink bug is dark brown, with sharp shoulder projections.

• Redhumped caterpillar

  The adult is a grayish brown moth. The larva is yellow with a red head and is lined longitudinally with orangish, black, and white stripes.

• 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.

• 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.

• Winter moth

  Adult male has grayish-brown wings; the female has remnants of wings and so cannot fly. This, in combination with the female's large body, makes the legs appear to be long, and gives her the superficial appearance of a spider.

• Periodical cicada

  Adults are wedge-shaped, nearly black, with red eyes and red-orange wing veins. The clear wings are held tent-like over the body.

• Silver leaf

  Silvering of the foliage is the characteristic symptom. At first, silvering may be associated with only one or two major branches, but eventually the entire tree becomes silvery in appearance. When infection is severe the leaves may curl upward.

• European earwig

  The European earwig is dark brown with an elongated body, equipped with pincer-like forceps at the rear of the abdomen. The short elytra do not entirely cover the abdomen.

• Replant disorders

  In general, trees suffering from replant disease show slow and uneven growth within the first three years of planting. Both specific and non-specific replant disorders are known.
