The potato ladybird beetle and the eggplant 28-spotted ladybird beetle are very similar in morphology. As soon as the potato sprouts, adults and larvae gather on vigorous plants to feed on the leaves and cause damage, overwintering as adults. Around April, the overwintered adults lay eggs in the field, and they emerge in July. In spring-planted areas, there is 1 generation per year. The larvae and adults of the 28-spotted ladybird beetle damage the leaves of vegetables such as eggplant, potato, tomato and cucumber, causing wilting. The larvae live on the underside of leaves. In warm regions, the adults have 2 to 3 generations per year, overwinter as adults, and generations overlap. After overwintering, the adults gather

The larvae and adults of the 28-spotted ladybird beetle damage the leaves of vegetables such as eggplant, potato, tomato and cucumber, causing wilting. The larvae live on the underside of leaves. In warm regions, the adults have 2 to 3 generations per year, overwinter as adults, and generations overlap. After overwintering, the adults gather in potato fields to cause damage, and after the potatoes wilt they migrate to eggplants to cause damage. The adults lay eggs on the underside of leaves; the eggs are yellow and stick together.

To control the potato ladybird beetle and the 28-spotted ladybird beetle, the following agents can be selected for spraying: 40% dimethoate 1000-1500 times dilution, 90% trichlorfon 1000 times dilution, 10% imidacloprid EC 2000 times dilution, 52.25% nongdile EC 1000-1200 times dilution, 2.5% fenvalerate 3000 times dilution, 48% lesiben EC 1000 times dilution, 24.5% azi EC 1500-2000 times dilution, 0.36% baicao No. 1 EC 1000 times dilution, etc.
