What are they?
Insect pests of potato can be categorized into three different general types. The most obvious ones are those that damage leaves or stems such as the Colorado potato beetle and flea beetles. Less obvious are those that damage tubers or roots, such as potato tuber moth, cutworms, wireworms, and white grubs or chafer grubs. Aphids and leafhoppers cause damage by feeding on the plant sap, and some are vectors of some important potato viruses. Because of their role as virus vectors (over 13 viruses are transmitted by aphids), aphids probably are of greater economic importance as potato pests worldwide than are defoliators or tuber pests.
Potatoes are grown under a wide range of ecological conditions, which greatly affect the distribution and abundance of specific insect pests. The importance of insect pests of potato often varies depending on the region, the growing season, and the production system. For instance, for potato seed production, the most significant insects are...
