Worms (Pseudococcidae) – the common name for the insect-winged insects of the coccid suborder, combining members of the family of lamellar, giant, paranormal and mealy worms, as well as felt, they are close relatives of the insects.
Mealybugs, or, as they are popularly called, shaggy lice, are sucking insects that are clearly visible with a simple eye. They got their name thanks to the white cotton-like waxy discharge. Larvae and adult females suck young shoots, leaves, buds. They strongly inhibit plants in growth. Insects are very mobile and move well at almost any age, covered with a powdery white wax coating, often with wax plates on the edge. Dimensions 3-6 (0.5-12) mm, depending on type. Sexual dimorphism is pronounced (when individuals of the same species have two forms that differ in physiological characteristics). The males have wings (usually the first pair), the limbs are normally developed, the abdomen with two tail threads. The oral apparatus is absent (males do not eat in the adult state).
In some species, the legs are reduced or absent. The oral apparatus is sucking. Most insects lay their eggs, in some species the females are viviparous. Eggs are laid in a white cotton-like facial bag. Fertility is very high; many forms give 2, sometimes up to 4 generations per year. Larvae of the 1st age (strollers) actively move around the feed plant, can be carried by the wind. Having stuck to a plant, larvae lose mobility; after molting, the larvae of the next age are again looking for places to feed. Adult females of some species can actively crawl along with the feed plant. Before egg laying, many forms leave the place of feeding and go into shelters.
In the world fauna, more than 1600 species of insects are widespread, but mainly in the tropics. Among the worms, there are many pests of fruit, industrial, ornamental crops and greenhouse plants. The most famous is the greenhouse platform, the Australian grooved insect (citrus pest, quarantine object), the bamboo insect, the citrus insect, the seaside insect, the grape insect, the Comstock insect (mulberry worm), and the olive pollinia. Some types of worms secrete useful substances used in the paint and varnish industry (varnish worm and cochineal, which gives red paint – carmine).
