Received January 16, 1961 A LTHOUGH the irradiation of Drosophila results in more crossover off spring, it has not been demonstrated that this effect has its origin in meiosis (WHITTINGHILL 1955) rather than in gonia1 exchange. Hence it is appropriate to irradiate specimens or stages which may have only oijgonia rather than the mixture of gonia and gametocytes carried by adults. Previous experi...

the mill moth, ephestia kuehniella zeller and indian meal moth, plodia interpunctella (hubner) are two injuriously important pests of stored products worldwide. harobracon hebetor (say) has been used as a biological control agent of moth’s larva in peanut storehouses and as well in packaged cereal products. in the present study, the efficacy of h. hebetor in parasitizing larva of the mill moth ...

Biological control of pest insects by natural enemies may be an effective, cheap and environmentally friendly alternative to synthetic pesticides. The cosmopolitan parasitoid wasp species Bracon brevicornis Wesmael B. hebetor Say (Hymenoptera: Braconidae) use lepidopteran as hosts, including insect pests like Ephestia kuehniella or Ostrinia nubilalis . Here, we compare the reproductive success ...

To test whether sex determination in the parasitic wasp Bracon sp. near hebetor (Hymenoptera: Braconidae) is based upon a single locus or multiple loci, a linkage map was constructed using random amplified polymorphic DNA (RAPD) markers. The map includes 71 RAPD markers and one phenotypic marker, blonde. Sex was scored in a manner consistent with segregation of a single "sex locus" under comple...
