• Green pug

  The adult is a grayish moth with mottled or scalloped dark striations toward the wing margins. The larva is a green inchworm with a dark head and a dark reddish brown dorsal mid-line present in later instars.

• 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.

• 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.

• Snowy tree cricket

  Adult somewhat resembles a field cricket, but is pale green in color and has a longer, more slender body and smaller head. Antennae are much longer than the body; males have stiff veins in their flat wings.

• Apple leaf (curling) midge

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

• Blister spot

  Lesions begin as small, darkened, water-soaked areas, generally around lenticels and typically on the lower half of the apple.

• Apple anthracnose

  Branch lesions first appear as small, circular spots that are purple or red when wet. As lesions enlarge, they become elliptical, sunken and turn orange to brown. A distinct margin develops between healthy and diseased tissue, which eventually causes the bark to crack around the infected area.

• Pear plant bug (Green apple bug)

  The adult pear plant bug is brownish yellow with two dark bands on the thorax and the extremities of its anterior wings are yellowish in color.

• Apple scab

  On leaves, young lesions are velvety brown to olive green with indistinct margins, and will often not be readily noticeable until after petal fall in commercial orchards.

• 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.

• Pear rust mite

  The overwintering stage is a light brown, wedge-shaped adult, which cannot be seen without a 15X hand lens. The summer forms are nearly white in color, and even smaller than the overwintered adults.

• Sparganothis fruitworm

  Adult is a vivid yellow moth with grayish magenta V-shaped marks on the forewings and reddish orange lace-like markings. Larvae are pale green with yellowish-green head.

• European fruit lecanium (Brown apricot scale)

  The adult female scale is nearly hemispherical and shiny brown, with several ridges along the back. Nymphs are light colored.

• Apple pith moth

  Head of adult is covered with white scales; forewings are narrow, mostly black or dark brown with white marks and usually with an irregular faint, rusty yellow line in the middle, and with two prominent black scale tufts.

• Green peach aphid

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

• Crown gall

  Infected trees are often stunted and produce small, chlorotic leaves. Spherical to elongated swellings along the roots or on the trunk just above the soil line is the primary symptom.

• Brooks fruit spot

  Appears as irregular, slightly sunken dark green lesions on immature fruit.

• Red velvet mites

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

• Apple mosaic virus

  Young leaves develop pale to bright cream-colored spots, blotches, bandings or patterns as they expand in the spring. These turn brown and become necrotic as they age and premature defoliation may occur when infection is severe.

• 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.
