Morphobioecological Peculiarities of the Main Xylophages Orchard Pests and their Entomophages on Absheron Peninsula

In the result of investigations carried out in Absheron Peninsula 12 species of xylophages pests from 7 families were found. Morphobioecological peculiarities distribution and practical importance of 7 most harmful species were studied. Ten species of entomophages were obtained from 12 registered species of xylophages. In four species of these (Xorides irrigator F., Atanycolus initiator Nees., Nudobius umbratus Motsch., Thanasimis formicarius L.) bioecological peculiarities and the role in reduction of xylophages populations were investigated. Four species of xylophages (Dicerca berolinensis Hbst., Leptura succedanea Lew., Morimus asper Sulz., Scolytus mali Bechst.) and two species of entomophages (Scambus terebrans Ratz., Tachuta nana Gyll.) are reported to the fauna of Azerbaijan for the first time.
