SOĞUKTA DEPOLAMANIN FARKLI KONUKÇULARDA YETİŞEN Trichogramma evanescens Westwood (HYM: TRICHOGRAMMATIDAE)’in FARKLI EVRELERİ ÜZERİNE ETKİLERİ / EFFECTS OF COLD STORAGE ON THE LIFE STAGES OF Trichogramma evanescens Westwood (HYM: TRICHOGRAMMATIDAE) RARED ON DIFFERENT HOST EGGS

Bu calismada yumurta parazitoidi Trichogramma evanescens’in yumurta, larva ve pupa evreleri cesitli konukcu [Ephestia kuehniella Zeller ve Sitotroga cerealella (Olivier)] yumurtalarinda 4°C de 10, 20, 30 ve 40 gun sureyle depolanmistir. Her bir konukcu icerisinde depolanan parazitoidlerin ergin cikisi, parazitleme performanslari ve omur uzunluklarinda depolama suresine bagli olarak onemli oranda azalma gozlenmistir. Depolama suresi cikan erginlerin cinsiyet oranlarinda onemli bir degisime neden olmamistir. Depolama suresi arttikca Sitotroga cerealella (Olivier) yumurtasinda gelisen parazitoidlerin omur uzunlugundaki azalma E. kuehniella yumurtasinda gelisenlerden cok daha fazla olmustur. In this study the eggs, larvae and pupae of the egg parasitoid Trichogramma evanescens in different host eggs [Ephestia kuehniella Zeller and Sitotroga cerealella (Olivier)] were stored as parasitized host eggs at 4°C for 10, 20, 30 and 40 days. Emergence, parasitization and longevity of the adults emerged from stored host eggs decreased depending on the storage periods. Sex rations of the adults were not effected by storage temperature and periods. The decrease of the adult parasitoid longevity emerged from S. cerealella eggs was more evident than that of E. kuehniella eggs.
