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...

The paper describes the monitoring of phytosanitary conditions in different regions Almaty region (Kazakhstan) and demonstrates large population cruciferous fleas (Phyllotreta cruciferae) on rapeseed plants, which reaches 7-9 spec./m2, exceeding economic injury level (3-5 spec./m2). disease is observed to spread wheat barley seeds. Proceeding from this, study aims develop effective protection m...

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...

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 ...

Parasitoids of dried-fruit insects were surveyed at a culled fig warehouse in Fresno, CA. Three parasitoids of pyralid larvae were found: Habrobracon hebetor (Say), Venturia canescens (Gravenhorst), and at least one species in the genus Goniozus Förster. Two parasitoids of pyralid pupae also were noted: Mesostenus gracilis (Cresson) and a new species of Psilochalcis Keifer. The latter is a new ...
