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 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 کاملInheritance of a temperature-modified phenotype of the short antennae (sa) mutation in a moth, Ephestia kuehniella (Lepidoptera: Pyralidae).
The autosomal recessive mutation short antennae (sa) causes considerable shortening of antennae in male and female Mediterranean flour moths (Ephestia kuehniella Zeller). However, the sa phenotype can be suppressed by several physical factors, making sa moths indistinguishable from wild-type moths (sa(WT)). This can be done by subjecting larva and pupa to a higher temperature (25 degrees C), to...
متن کاملInfluence of Temperature and Relative Humidity on the Insecticidal Efficacy of Metarhizium anisopliae against Larvae of Ephestia kuehniella (Lepidoptera: Pyralidae) on Wheat
A series of laboratory bioassays were conducted for the evaluation of the insecticidal efficacy of an isolate of Metarhizium anisopliae (Metschnikoff) Sorokin (Ascomycota: Hypocreales) against larvae of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae), under various temperature-relative humidity (r.h.) conditions. The fungus was applied at four doses (0, 8 × 106...
متن کاملimpact of pyriproxyfen and methoxyfenozide on hemocytes of the mediterranean flour moth, ephestia kuehniella (lepidoptera: pyralidae)
the mediterranean flour moth, ephestia kuehniella zeller, is one of the major pests in stored products worldwide. several problems assossiated with the use of conventional insecticides have strongly demonstrated the need for applying alternative safe compounds such as insect growth regulators (igrs). in the present study, growth regulating activity and hematological effects of pyriproxifen and ...
