Insect Management Handbook

Pest description and crop damage Aphids, leafhoppers, gnats, and many other insects present a problem at harvest time, especially if berries are machine harvested. The machine harvester shakes insects from the plants, potentially contaminating berries going into the harvest trays.

Management-cultural control

Correct adjustment of air-blast or vacuum-suction cleaner systems during harvest can lessen insect contamination of machine-picked berries.
