Mites

Mites are very small insects with four pairs of legs in the adult state. Many species of mites are parasites of animals and plants, which sting with the buccal appendages, called chelicerae, which unite and lengthen form a real stiletto, with which the mite goes to empty the cells of their contents. As a consequence, malformations and galls are formed especially on the leaves and buds, as well as abnormal enlargements of the hairs caused by substances emitted by the mite. Other symptoms characteristic of their attack are chlorosis and leaf wilt. Furthermore, some types of mites, such as spider mites or "spider mites", produce a whitish web that forms a floury or flocky mass as protection for the eggs, usually on the underside of the leaves. The cycles and populations of mites are strongly influenced by climatic factors: they are favored by high temperatures and relative humidity around 60%. Being poorly protected from climatic conditions, consequently we often witness real migrations on the plant in search of more favorable microclimates, or a state of quiescence awaiting more favorable conditions.

The pesticides used in the fight against harmful mites, called acaricides, can act by contact, by ingestion, by asphyxiation. There are also effective formulations against eggs. The important thing is to intervene as soon as possible, when the infestation is still limited.

Some species of mites, however, are useful to humans as parasites of other harmful mites and insects and as such can be used in biological control to defend plants of agricultural interest.
