Their bodies are small, oblong, and their color is different: from pale yellow to coal black. The length does not exceed 3 mm. Thrips are very fertile, adults are able to fly.
Thrips are omnivorous, but prefer beautifully flowering crops: hibiscus, violet, geranium. Delicate young leaves and shoots are especially vulnerable to them. Varieties with dense leaves are less interesting to insects. Under their attack, the bush is covered with small punctures, dots of a yellowish tint. Small black specks of excrement also become visible. Thrips settle on green aboveground parts and in a soil coma. You need to know this when starting to destroy the colony in order to process all the infected areas.
How to fight
1. The buds and flowers are removed, since the largest number of beetles accumulates here.
2. In a small amount of water, a zoo shampoo against ticks, which contains permethrin, is diluted. Beat it into a dense foam. It is applied to the stems and leaves, left for 35-40 minutes, then washed off.
