This pest is present and working in just about every state. Destroy any potato bugs you see and check the underside of leaves for their orange egg masses. Both the adults, which are yellowish with black stripes, and the larvae, which are dark red or orange with black spots, feed on potato foliage. Pick them off or spray Bacillus thuringiensis San Diego on the young larvae. Bt San Diego attacks only the potato beetle larvae and is harmless to beneficial insects, animals and humans.
Flea beetles are tiny, black or brown, and pesky.
They chew small holes in plant leaves and can do serious damage fast if they attack young plants. Dust with rotenone to control them. These tiny insects can transmit virus diseases. They suck juices from the leaves and stems of potato plants, injuring them badly. Insecticidal soap sprays are an effective control.
