Özet

Bracon hebetor (Say) (Hymenoptera: Braconidae) is among the most widely used biological control agents against lepidopteran pests of stored products. The importance of floral nectars and artificial diets as food sources for B. hebetor was assessed in the laboratory by testing the effect of different floral nectars (dandelion, dog-fennel, dead nettle, willow, plum) and artificial diets (honey, grape molasses, raisins, molasses, glucose and sucrose syrups, and egg yolk) on longevity, fecundity and adult emergence. B. hebetor females lived longer when fed on wett raisin (46.6 days), sucrose (45.2 days), Glucose (43.8 days) and honey (42.8 days) than those fed on other floral nectar and/or other artificial diets. The females fed on water, molasses and without food showed the shortest longevity (8.4, 6.9 and 6.8 day, respectively). B. hebetor females that fed on sucrose, honey + egg yolk and molasses laid more eggs (22.4, 21.9 and 20.6, respectively) than those fed on the other sources. The females fed on dead nettle, dandelion and plum flower nectar showed the least fecundity (17.1, 14.6 and 14.5 eggs, respectively).
