Embryophagum ( Bdhym.: Trichogrammatidae), For Control Of Stored Products Moth Pests In Bulk Wheat [Elektronische Daten] [M. Schöller, S. Hassan, Ch. Reichmuth] Evaluation de Trichogramma evanescens et T. embryophagum (Hym. Trichogrammatidae), pour la lutte biologique contre Ephestia spp. dans du blé stocké (Lep. : Pyralidae) The potential ofTrichogramma evanescens Westwood andT. embryophagum Quednau to controlEphestia kuehniella andE. elutella was evaluated under laboratory conditions. BothTrichogramma species parasitised eggs of the twoEphestia spp. in bulk wheat at 1, 2 and 5 cm depth. The release ofT. evanescens was more effective than that ofT. embryophagum resulting in higher rates of parasitism, predation and parasitoid induced mortality. At 17‡C and 26‡C, the mortality ofEphestia due to the release ofT. evanescens was 67, 78% and ofT. embryophagum 27 and 38%, respectively. The difference in host finding efficiency between the two species was large, at 5 cm depth and 26‡C,T. evanescens parasitised about four times more host eggs compared to T.embryophagum.
