Non-diapausing spider mites (Tetranychus urticae) live on the undersurface of host leaves during summer, but diapausing mites overwinter in dark hibernacula. The light environments of these habitats differ: visible radiation (VIS) but not ultraviolet radiation (UV) reaches the undersurface of leaves, but neither enters dark hibernacula. Thus, mites of either seasonal form could locate their pre...

We examined induction of preference and performance on novel host plants for two laboratory populations of the polyphagous spider mite Tetranychus urticae, with one population adapted to bean and the other population adapted to tomato. We bred four isofemale lines of the bean population only and used them in all the assays. The bean population had a 30% lower fecundity on tomato than on bean, w...

This preliminary communication presents the first record of predaceous thrips Scolothrips longicornis Priesner, 1926 (Thysanoptera: Thripidae) in Slovakia. As a well known predator of numerous spider mites, e.g. Tetranychus urticae or Eutetranychus orientalis it has been considered as a suitable biological control agent recently. Tetranychids mites are harmful agriculture pests, causing damage ...
