Biology

Most species
are hyperparasites of Aphididae or of other plant sucking Hemiptera (Coccoidea,
Psylloidea) through their Braconidae (Ichneumonoidea) or Aphelinidae and
Encyrtidae (Chalcidoidea) primary parasitoids, or are primary
parasitoids or hyperparasitoids of the predators of these plant pests (Diptera:
Syrphidae, Chamaemyiidae; Coleoptera: Coccinellidae; Neuroptera:
Chrysopidae). Some species are also recorded as pupal parasitoids of
mining or gall forming Diptera (Agromyzidae, Chloropidae, Cecidomyiidae)
or as egg parasitoids of several families of Lepidoptera (apparently as
hyperparasitoids), and there are rare records from other families of
Diptera, Hymenoptera and Coleoptera (Gibson, 2001; Noyes, 2014). |
