Biodiversity of hymenopteran parasitoids

open access: yesCurrent Opinion in Insect Science, 2023
Parasitoid wasps are the most successful group of insect parasitoids, comprising more than half the known diversity of Hymenoptera and probably most of the unknown diversity. This lifestyle has enabled them to be used as pest control agents conferring substantial economic benefits to global agriculture.
