67 results about "Ichneumonidae" patented technology

The Ichneumonidae are a parasitoid wasp family within the order Hymenoptera. Unlike other parasites, parasitoids kill their hosts. Ichneumonids are important parasitoids of other invertebrates; common hosts are larvae and pupae of Coleoptera (beetles), Hymenoptera (wasps and relatives), and Lepidoptera (moths and butterflies). About 25,000 species have been described worldwide. Estimates of the total species range from 60,000 to over 100,000 – more than any other hymenopteran family.
