Özet

Storage at low temperature is a valuable and simple method for improving parasitoid mass rearing techniques. The effects of cold storage on Trichogramma pintoi Voegele (Hymenoptera: Trichogrammatidae) were investigated by holding different life-stages (larval, pre-pupal and pupal stages) at -5, 0, 5, and 10 degrees C on Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) and Cadra cautella Walker (Lepidoptera: Pyralidae) for 10 days storage periods. Cold storage at -5 and 0 degrees C resulted in high mortality, especially at larval and pre-pupal stage of parasitoid, as a host C. cautella. However, development time increased and emergence ratio of T. pintoi decreased with storage temperature in all immature stages and host species. Longevity and parasitism ratio of adult parasitoids were affected by the host species and the storage temperature. Our results indicate that low temperature storage (5 and 10 degrees C) of T. pintoi within its host (E. kuehniella pupal stage of T. pintoi) for maintaining and accumulating the parasitoid during the release program.
