Adults jump or fly readily when disturbed while the nymphs run sideways across the leaf and over the edge. Development from egg to adult takes about three weeks in warm weather. Very large leafhopper populations can build up in a short time during the summer. Occasional Pests A variety of other insects may be numerous at times. Control decisions should be based on the extent of the infestation in the field and the severity of damage.
Blister beetles are narrow, elongate insects.
They may be found feeding in clusters on potato leaves. Infestations are usually localized within fields and treatment of an entire field is seldom necessary. Rarely do blister beetles do enough damage damage to cause any yield loss. Hornworms are easily identified and will feed on potato foliage. These worms can consume large amounts of foliage but severe infestations are not likely to occur.
