Influence 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 کاملConsumption of Bt Maize Pollen Containing Cry1Ie Does Not Negatively Affect Propylea japonica (Thunberg) (Coleoptera: Coccinellidae)
Propylea japonica (Thunberg) (Coleoptera: Coccinellidae) are prevalent predators and pollen feeders in East Asian maize fields. They are therefore indirectly (via prey) and directly (via pollen) exposed to Cry proteins within Bt-transgenic maize fields. The effects of Cry1Ie-producing transgenic maize pollen on the fitness of P. japonica was assessed using two dietary-exposure experiments in th...
متن کاملConsumption of Bt rice pollen containing Cry1C or Cry2A does not pose a risk to Propylea japonica (Thunberg) (Coleoptera: Coccinellidae)
As a pollen feeder, Propylea japonica would be directly exposed to Cry proteins in Bacillus thuringiensis (Bt)-transgenic rice fields. The effect of Cry1C- or Cry2A-containing transgenic rice pollen on the fitness of P. japonica was assessed using two dietary-exposure experiments in the laboratory. In the first experiment, larval developmental time of P. japonica was significantly longer when f...
متن کاملتاثیر هگزافلومورون بر متابولیسم حدواسط شب پره بید آرد (Ephestia kuehniella Zeller (Lepidoptera: Pyralidae
بید آرد Ephestia kuehniella یکی از آفاتی است که سالانه خسارت زیادی را به محصولات کشاورزی انباری وارد میکند. در مطالعه حاضر، تغییر فعالیت آنزیم های سم زدا، برخی از آنزیم های موثر در متابولیسم حدواسط (آلانین و آسپارتات آمینوترانسفراز، لاکتات دهیدروژناز) و مقدار برخی از ترکیبات غیر آنزیمی (پروتئین، تری گلیسرید و گلیکوژن) تحت تاثیر غلظت های مختلف هگزافلومورون بررسی شد. لاروهای تیمار شده با غلظ...
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...
