Trichogramma parasitoids alter the metabolic physiology of Manduca eggs.
Egg parasitoids face unique developmental constraints. First, they have exceptionally limited resources to support themselves and their siblings through three life stages. Second, they develop within the physiological system of another species, which they modify to their own ends. We examined how these constraints affect the metabolic physiology of egg parasitism, and whether parasitoids retool...
متن کاملImpact of insecticides used to control Spodoptera frugiperda (J.E. Smith) in corn on survival, sex ratio, and reproduction of Trichogramma pretiosum Riley offspring
Corn (Zea mays L.) is cultivated in large areas and considered one of the world’s major cereal crops. There are several arthropod pests that can reduce its production such as the fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lep.: Noctuidae), which is considered to be the main pest for corn. Fall armyworm is primarily controlled by insecticides. The use of biological control agents to mana...
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 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...

Fall armyworm Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) is an important pest of maize (Zea mays L.) crops in Brazil. The effects of beta-cypermethrin, chlorfenapyr, chlorpyrifos, spinosad, etofenprox, triflumuron, alpha-cypermethrin/teflubenzuron, and lambda-cyhalothrin/thiamethoxam on Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) immature stages we...
