Managing Vineyard Insect and Mite Pests

Sucking Insects

Sucking pests have mouthparts for piercing vine tissues and sucking out vine sap. Because they do not chew, they do not leave noticeable holes in the vine tissue. Many inject saliva into the vine during feeding, which can distort normal growth. Additionally, many sucking pests transmit microorganisms that cause vine diseases. Sucking pests include aphids, leafhoppers, and mealybugs. Mites cause vine damage similar to that of sucking insects, although their actual feeding mechanism differs somewhat.
