• Black pox of apple (blister canker of pear)

  On apple, conical, smooth, shiny black swellings are evident on current season's growth. As lesions age, they become ovoid with raised borders. On leaves, lesions begin as small, circular green spots surrounded by a red halo.

• Pear thrips

  Adult is slender and brown, with short antennae and a swelling behind the head; the wings are long and narrow, with fringes of long hairs.

• Forbes scale

  Round or elongate gray scale with a raised reddish area in the center, which distinguishes it from the San Jose scale.

• 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.

• 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".

• Pear midge

  The adult resembles a very small mosquito or gnat; the body is brown and the wings transparent with simple veins. The larva is a white maggot with no legs or visible head; the posterior end is blunt, and the front end tapers to a point.

• Cherry fruit flies

  The adult cherry fruit fly is somewhat smaller than the house fly, with a yellowish brown head and legs, and white crossbands on the abdomen. The black cherry fruit fly is slightly larger and its abdomen is entirely black.

• Humped green fruitworm

  Adult's forewings are gray and marked with light and dark areas for 2/3 of their length the outer 1/3 is a lighter gray.

• 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.

• Widestriped green fruitworm

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

• 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.

• Phytoseiid mites

  A dark mark in the form of an "H" sometimes appears within their body. This mark is red when they feed on European red mites and yellow when they feed on twospotted spider mites. They move very rapidly on the leaves.

• Sooty blotch

  Sooty blotch and flyspeck are found together on the same fruit and affect only the epidermal layer of the fruit. Sooty blotch appears as various shades of olive-green on the surface of the fruit.
