rearing methods for bracon hebetor (say) (hym., braconidae) were investigated in the series of laboratory experiments designed to enhance the yield of the mass rearing of this parasitoid for biological control of lepidopteran field and stored product pests. in these experiments, the effects of parasitoid and host densities on fertility and sex ratio of b. hebetor were assessed. in parasitoid de...

Hydrocarbon and wax ester components of cuticular lipids of the braconid parasitoid Habrobracon hebetor Say reared at 25 degrees C on larvae of a pyralid moth have been identified by GC-MS and analyzed with respect to adult age, mating status, and diet. The hydrocarbons range in carbon number from C(21) to C(45) and consist of a homologous series of n-alkanes, 11-, 13-, and 15-methyl alkanes, 1...

grape berry moth, lobesia botrana (denis and schiff.) is a destructive pest of grapevine in orumieh (northwest, iran) vineyards. it is mainly controled through application of broad-spectrum insecticides, which can adversely affect vineyard ecosystem and consequently human health. since a first step in setting up an ipm program is to assess the biological control agents within the ecosystem, so ...

a total of 29 species in 16 genera and 8 subfamilies of the braconids (hym., braconidae) were collected from alfalfa fields in bahariya and farafra oases (western desert, egypt) these species were identified, together with details of the sites where they were found and an indication of their relative abundance in each site. among the samples, 4 species in 4 genera and 3 subfamilies are recorded...

the flour moth, ephestia kuehniella zeller and indianmeal moth, plodia interpunctella (hubner) are reported as important pests of stored products in many countries throughout the world. in recent years harobracon hebetor (say) wasp has been employed as a biological control agent of the moths' larvae in peanut warehouses as well as in packaged cereal products. in this study the functional r...
