原始语种摘要: Bracon hebetor Say (Hymenoptera : Braconidae), is a larval parasitoid of various lepidopteran hosts. It also acts as a menace in biocontrol laboratories by completely parasitizing the laboratory host Corcyra cephalonica (Stainton). A study was conducted to determine the effect of host instars of C. cephalonica on the parasitism behaviour of B. hebetor. A gravid female parasitoid was selected to study the host selection behaviour in different instar larva. Ethograms were constructed for the host parasitisation behaviour of B. hebetor on each instar of corcyra larva which illustrates the transition between the different behavioural events. The duration of each behavioural step was calculated. The results showed that the parasitoid showed significant ovipositional behaviour from the 3rd...
