Predatory mites

Predatory arachnids (Gamasida), which as parasites are among the most important and effective beneficial insects in viticulture. The insects, which belong to the mite order, are found on numerous plants. They are characterised by mouthparts with scissor-like graspers and clear scales on the top and underside of the body. The most important representative is the species Typhlodromus pyri, which measures around 0.3 to 0.5 millimetres. It has a pear-shaped body with four pairs of legs and a milky white to brownish colour.

Preying insects

The females overwinter in bark scribbles on the stem, and in spring the eggs are laid on the undersides of the leaves. The hatched adults feed mainly on the most harmful mite species for viticulture: the red spider mite, curly mite and pox mite (leaf gall mite), as well as vine thrips and cicadas and their eggs. After being eaten by red spiders, they turn a reddish colour (picture right).
