Adaptation of Habrobracon hebetor (Hymenoptera: Braconidae) to Rearing on Ephestia kuehniella (Lepidoptera: Pyralidae) and Helicoverpa armigera (Lepidoptera: Noctuidae)
Food characteristics strongly regulate digestive enzymatic activity of insects through direct influences on their midgut mechanisms. Insect performance is better on diets that contain nutrients in proportions that fit its digestive enzymes. Little is known about the influences of rearing history on parasitism success of Habrobracon hebetor Say. This research focused on the effect of nutrient re...
متن کاملInfluence of Larval Density on Biological Fitness of Ephestia Kuehniella Zeller (lepidoptera: Pyralidae)
Mediterranean flour moth, Ephestia kuehniella, is a cosmopolitan pest of stored products, and its eggs are widely used to rear parasitoids and predators for biological control programmes. This experiment investigated how larval population density affected the survival rate and reproductive output of this species under four rearing densities ( larva per 2 g food per vial; or 00, 500 or 000 larva...
متن کاملEffect of storage temperature and duration on viability of eggs of Helicoverpa armigera (Lepidoptera: Noctuidae).
The ability to store different insect stadia for prolonged periods provides considerable flexibility and ability to conduct experiments properly. Therefore, studies were undertaken to determine the effect of storage temperature and duration on viability of eggs of Helicoverpa armigera (Hübner). The percentage egg hatch and incubation period were significantly (P=0.01) influenced by egg age, sto...
متن کاملage-specific functional response of trichogramma brassicae (hymenoptera: trichogrammatidae) parasitizing different egg densities of ephestia kuehniella (lepidoptera: pyralidae)
the parasitoid trichogramma brassicae bezdenko is used for inundative releases in biological control programs against lepidopteran pests in agro-ecosystems. age-specific functional responses of t. brassicae to different egg densities (5, 10, 20, 30, 40, 60, and 80) of sterilized eggs of ephestia kuehniella at 23±1°c, 60±5% rh, and 16:8 h (l:d photoperiod ) were studied. e. kuehniella densities ...
متن کاملEffects of shelf architecture and parasitoid release height on biological control of Plodia interpunctella (Lepidoptera: Pyralidae) eggs by Trichogramma deion (Hymenoptera: Trichogrammatidae).
The effects of shelving type, packaging, and release height on success of Trichogramma deion Pinto & Oatman (Hymenoptera: Trichogrammatidae) parasitizing Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) eggs was studied under laboratory conditions. In trials on multipletiered gondola-type or open shelving units, with or without packaging, foraging success was evaluated by comparing paras...
