Last Updated: 2024/11/06, The morphology of potato ladybug is very similar to that of eggplant 28 ladybug. As soon as the potato sprouts, the adults and larvae concentrate on the growing plants to feed on the leaves to survive the winter. The overwintering adults lay eggs in the field around April and emerged in July. One generation a year occurs in spring sowing areas. The larvae and adults of 28 ladybug damage the leaves of eggplant, potato, tomato, cucumber and other vegetables, causing wilt. The larvae live on the back of the leaves. Adults occur for 2-3 generations a year in warm areas, overwintering as adults, and generations overlap. Adult colonies after overwintering

The potato ladybug is very similar in morphology to the nightbug. As soon as potato budded, adults and larvae concentrated on well-growing plants to feed on leaves and overwinter as adults. Overwintering adults lay eggs in the field around April and emerge in July. One generation occurs a year in spring sowing area.

The larvae and adults of ladybug 28 punctatus harm the leaves of eggplant, potato, tomato, cucumber and other vegetables, causing wilt. The larvae live on the back of the leaves. Adults occur 2~3 generations a year in warm areas, overwintering as adults, and generations overlap. After overwintering, the adults swarm in potato fields and migrate to eggplant fields after potato withers. Adults lay eggs on the back of leaves, yellow eggs, eggs stuck together.

To control potato ladybug and beetles, 40% dimethoate 1000~1500 times solution, 90% trichlorfon 1000 times solution, 10% high-effect methomyl EC 2000 times solution, 52.25% Nongdile EC 1000~1200 times solution, 2.5% kungfu pyrethroid 3000 times solution, 48% Rospen EC 1000 times solution, 24.5% Azizi EC 1500~2000 times solution, 0.36% Baicao No.1 EC 1000 times solution and other pesticides spray.
