PREDATORS AND PARASITES OF SPIDERS (ARANEI) OF THE SAMARA REGION

Spiders are the predators and often play an important role in the regulation of insect and other invertebrate animals. However, the importance of spiders as fighters arthropods is somewhat reduced due to the large number of existing natural enemies. The spiders lead the hunt for food animals of the classes Reptilia and Amphibia. The birds (Aves) feed their chicks with spiders. Mantispa styriaca L. (Neuroptera) uses in food of spiders. The ants of the genera Formica and Myrmica catch and carry spiders to the nest. Some species from the order Diptera and the subclass Acarina parasitize on the spiders' body. The wasps (Sphecidae) stock spiders in cells for rearing their larvas. The most dangerous and numerous enemies of spiders are road wasps of the family Pompilidae , the order Hymenoptera. Spiders can pose a threat to other spiders, which are used to eat not only other spiders species of, but the juveniles of their own species. Our work provides data on 39 species of spiders living in the Samara region, with more than 48 species of predators and parasites.
