چکیده
This project executed in Gulan and Mazandran Provinces. In each provinces two main sites were selected which in these sites, trapping by eggs of Mediterranean flour moth, Ephestia kuehniella and Angoumois grain moth, Sitotroga cerealella, to collect Trichogramma wasps were performed. For preventing of mixing on trichogramma species, trapping places were selected far from rice fields. In trapping, tree species, traps color, and light factor were considered. The traps in four color, were placed on more than 10 species in two light conditions (forest margin and deep). But because of very low rate of parasitism, the amount of parasited traps in compare with all of traps were very low that analyzing of effect of tree species and trap color in rate of parasiting were impossible. But light factor in attracting of trichogramma wasps was effected. So parasited traps in forests margin were 26.6% however in low light places of forests were 6.9% of total traps. Five specimens of collected wasps were sent to Mr. Nai-quan from china. He recognized specimens as Trichogramma chilotraeae Nagaraja & Nagarkatti, 1969. 36 In this project possibility of control of three important forest pests contain: Leucoma wiltshirei Coll., Holcocerus nr. tancrei and Ocneria terebinthina stgr. by trichogramma wasps was studied. according to this study, the eggs of two pests, Leucoma wiltshirei. and Holcocerus nr. Tancrei were parasited by parasitoid and two generations of parasitoid wasps were reared on these pests eggs. However wasps were very active on eggs of Ocneria terebinthina, but no wasps emergence from eggs. Of four sites in two provinces we collected trichogramma wasps from only three sites, Shahid Zare Park, Saravan forest and Pilambara Research Station.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
