Abstract
Trissolcus species (Hymenoptera, Scelionidae) are important egg parasitoids of Sunn pest, Eurygaster integriceps Put. (Heteroptera, Scutelleridae). They need alternative host eggs to survive in the nature, at the end of the wheat growing season. This study was carried out to determine the alternative hosts of Trissolcus species and host-parasitoid interactions in laboratory and different ecosystems in Adıyaman, Diyarbakır and Şanlıurfa provinces during 2007-2009. The parasitoid adults were reared from Scutelleridae and Pentatomidae (Heteroptera) eggs, collected from wild plants and kept in tubes in the laboratory at 25±1ºC and 65±5% r.h. In this study, it was determined that 23 species belonging to Pentatomidae and Scutelleridae are alternative egg-hosts of Trissolcus spp. 13 species of which have been identified as the first time for alternative hosts of Trissolcus species.
Key words: Trissolcus species, alternative hosts, Southeastern Anatolia Region, Turkey.
