age-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 کاملEffect of feeding and male presence on some biological characteristics of female Trichogramma brassicae (Hymenoptera: Trichogrammatidae)
کیفیت پایین دشمنان طبیعی در شکست برنامه‌های کنترل بیولوژیک نقش دارد. در پژوهش حاضر تأثیر تغذیه از عسل و مدت زمان حضور نرها بر برخی خصوصیات زیستی زنبور پارازیتوئید Trichogramma brassicae Bezdenko مورد مطالعه قرار گرفت. چهار تیمار عبارت بودند از: حضور پارازیتوئید نر به مدت 24 ساعت همراه با پارازیتوئید ماده با عسل و بدون عسل؛ حضور پارازیتوئید نر برای تمام عمر همراه با پارازیتوئید ماده با عسل و بد...
متن کاملAdaptation 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 کاملTemperature Effects on the Development and Reproduction of Three Trichogramma (Hymenoptera: Trichogrammatidae) Species Reared on Trichoplusia ni (Lepidoptera: Noctuidae) Eggs
The cabbage looper, Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) is a generalist species and an important pest of Brassicaceae worldwide. Egg parasitoids are a feasible alternative for the control of this species. We evaluated the suitability of T. ni eggs as hosts for three Trichogramma Westwood (Hymenoptera: Trichogrammatidae) species and their tolerance to survive and develop within a r...
متن کاملDevelopment and reproduction of Podisus distinctus (Heteroptera: Pentatomidae) fed on larva of Bombyx mori (Lepidoptera: Bombycidae).
Biological control has been reducing the use of chemical products against insect pests, especially predatory Pentatomidae. Species of this group can present high variations in their life cycle as a result of their diet. Thus, the objective of this research was to study nymph development and reproduction of Podisus distinctus (Stäl, 1860) (Heteroptera: Pentatomidae) fed on Bombyx mori L., 1758 (...
