Peppers

Piercing and sucking creates superficial spots (white on young fruit or yellow on mature fruit) known as "cloudy spot" on tomato and other fruits.

Borers make pinhole entrances, exuding sawdust-like frass. The foliage above bored stems may wilt or break. Borers enter peppers near the stem and feed on the seed core.

Specific virus diseases are difficult to distinguish and produce a wide range of symptoms including stunted, slow-growing plants, twisted, crinkled, cupped, or deformed leaves, and leaf discoloration (yellow mottling and mosaic patterns, ringspots, and dark-green banding).

Bacterial wilt can cause sudden wilting of cucumbers, melons, and summer squash.
