Plant bugs
Lygus hesperus
Pest description and crop damage Adult plant bugs are flattened, semi-oval insects 0.19 to 0.25 inch long. They can be yellow, green, and dark brown to black with a conspicuous yellow or pale green triangle on the back. Adult stink bugs have a flattened shield shape. Length ranges from 0.25 to 0.5 inch and color from gray to brown to green. Stink bugs are noisy fliers, with long, piercing-sucking mouth parts.
Bug feeding damage causes dimpling and sunken spots on young fruit that can deform the shape of the fruit by harvest (often referred to as cat-facing). Internal fruit damage appears as white corky areas under the surface of the fruit. Feeding may deform or kill buds and shoots. These bugs have an extremely wide host range that includes field and vegetable crops, hay crops, natural vegetation in uncultivated land and weeds in adjacent areas. These pests do not reproduce on tree crops, but invade from outside hosts.
