Diversity of sex-determining alleles in Bracon hebetor [PDF]
Heredity, 1999 In many hymenopterans, sex is determined at a single polymorphic 'sex locus'. Individuals that are heterozygous at this locus develop as females whereas homozygotes and hemizygotes develop as diploid and haploid males, respectively. Diploid males are developmentally inviable or sterile, and the likelihood of diploid male production depends in large ...

Performance of parasitoid Bracon hebetor (Say.) (Hymenoptera
Journal of Knowledge Learning and Science Technology ISSN: 2959-6386 (online), 2023Harbobracon hebetor say (Hymenoptera: Braconidae) is a gregarious larval ectoparasitoid of several species of Lepidoptera that are associated with stored products. The present study addresses the effect of photoperiod of H.Hebetor reared on the host C. cephalonica. The results revealed that the effect of photoperiod of H.

Mating system of Bracon hebetor (Hymenoptera: Braconidae)
Ecological Entomology, 1992Abstract. We report on the mating system of a field population of the parasitic wasp, Bracon hebetor , on a corn pile infested by the Indian meal moth, Plodia ...

Sex ratio and foundress number in the parasitoid wasp Bracon hebetor
Animal Behaviour, 1994Abstract Abstract. As predicted by the theory of local mate competition, the offspring sex ratios of many parasitoid wasps become increasingly male biased as the number of conspecific females ovipositing in a patch rises. The braconid wasp Bracon hebetor appears to be an exception.

Host Effects on Functional and Ovipositional Responses of Bracon hebetor
The Journal of Animal Ecology, 1988SUMMARY (1) This study describes the effects of host species (Anagasta kiihniella (Zeller) and Plodia interpunctella (Hiibner)) and size on the 'functional' and 'ovipositional' responses of the gregarious parasitoid Bracon hebetor Say, and its preferences between these host types.

Fluoroacetate-Induced Changes in the Fecundity and Fertility of Bracon hebetor Female12
Journal of Economic Entomology, 1976A single meal or injection of sodium fluoroacetate, an inhibitor of the tricarboxylic acid cycle, decreased braconid egg production for the subsequent life of the female. However, low hatchability characterized only the eggs laid on the 1st few days post-treatment. Microscopic examination of dissected ovarioles revealed inadequate vitellogenesis of the

Sterility in Adult Bracon hebetor (Hymenoptera: Braconidae) Induced by 5-Fluorouracil
Journal of Economic Entomology, 1988Female Bracon hebetor (Say) experienced limited reductions in fecundity and fertility when fed 0.05 and 0.1% 5-fluorouracil. Both sterility effects were associated with altered RNA metabolism in a combination of target cells not previously identified in earlier studies of 5-fluorouracil on arthropods or tests of the response of B.

Comparative Mutagenicity of Two Chemosterilants, Tepa and Hempa, in Sperm of Bracon hebetor
Science, 1966In an assessment of the mutagenic efficiency of the alkylating agent, tepa, and its nonalkylating analog, hempa, both chemicals induced a high frequency of recessive lethal mutations in the sperm of the parasitic wasp, Bracon hebetor Say ( Habrobracon ), although tepa was the more efficient ...

Genetic response of adult Bracon hebetor (say) to alkylation by ethylenimine
Mutation Research, 1972Abstract Experiments were performed to characterize the genetic and physiological damage induced by ethylenimine (EI), a monofunctional alkylating agent, on adult Bracon hebetor. These studies were specifically designed to enable a comparison with our previous data obtained with another aziridine compound, the hexafunctional agent apholate.
