Bruchid-parasitoid

• Dinarmus

  Dinarmus is a genus of chalcidoid wasps in the family Pteromalidae with nearly cosmopolitan distribution. Species in this genus are larval-pupal ectoparasitoids of bruchid beetles (Chrysomelidae: Bruchinae), particularly pests of stored legume seeds such as cowpea. The genus includes economically important biological control agents, notably D. basalis and D. vagabundus, which are deployed in integrated pest management programs targeting Callosobruchus species. Research on D. basalis has revealed complex host discrimination behaviors, facultative superparasitism, and olfactory host location mechanisms.
