White fly

Adult greenhouses appear in greenhouses and settle on the inner side of the leaves of plants. Here they lay small oblong eggs.Fertile females are able to postpone them to two hundred pieces in one cycle. After a week, a huge number of children appear, in appearance resembling yellowish-transparent scales. In its development, the insect goes through several stages:

1. Larvae stage. Initially, they are almost invisible, they can be detected with great difficulty. The worms move in search of a comfortable place for several hours after birth. Having found it, they become immobile, the process of intensive food larvae. It is this time that is most favorable for destroying the whitefly in a greenhouse. After two weeks, she stops feeding, her body is enveloped in a dense wax coating that makes the larva invulnerable.
2. Nymph or pupa. In this state, insects are resistant to any drugs. They continue to feed on plant sap, after 10-16 days they turn into imago.
3. Adult. Some time imago remain on the leaves. With a small number, whiteflies do not fly away from the chosen bush.

Harm caused

The presence of whitefly on plants causes them irreparable harm. A large amount of juice drunk by parasites deprives the green space of vital forces, and massive punctures of the leaf surface violate the process of natural photosynthesis. Sucking insects are carriers of infections and diseases such as chlorosis, jaundice, leaf curl, fruit necrosis. Whitefly on cucumbers, tomatoes and other crops slows their growth, which affects the yield.

Whitefly on cabbage

The product of insect life is a dull white liquid, called honeydew. It serves as a favorable environment for the reproduction of pathogenic microflora.
