They are characterized by mouth tools with scissor-like grippers and by clear labels on the top and bottom of the body.

The species Typhlodromus pyri is grown in the laboratory and in the framework of the Biological crop protection specifically in the vineyard to combat these pests as an environmentally friendly alternative insecticides exposed. The predatory mites spend the whole year on the Rebstock and are therefore exposed to all adverse influences such as the use of chemical agents (spraying). This is what the Integrated crop protection through as little / no use of pesticides Considered.
