Holepyris sylvanidis (Brèthes) (Hymenoptera: Bethylidae), a parasitoid of Tribolium confusum Jacquelin du Val and T.?castaneum (Herbst) (Coleoptera: Tenebrionidae)]]>

摘要

Parasitoids can suppress populations of their host and thus play a primary role in Integrated Pest Management. We studied foraging cues inHolepyris sylvanidis(Hymenoptera: Bethylidae), a larval parasitoid ofTriboliumspecies, in a four-chamber olfactometer.H.?sylvanidisis reported as a cosmopolitan parasitoid of Coleopteran including two major pests of stored products, the confused flour beetleTribolium confusumand the red flour beetleT.?castaneum. Our study reveals that the host complexes of bothTriboliumspecies and different living host stages attract naiveH.?sylvanidisfemales, whereas no reaction was observed to uninfested substrates. Our findings may contribute to the development of biological control strategies ofT.?castaneumandT.?confusumwith parasitoids.
