HYMENOPTEROUS PARASITOIDS

APHELINIDAE

Worldwide, the majority of Aphelinidae are parasitoids of sternorrhynchous Homoptera. While a few attack species of Aphidoidea, Aleyrodoidea or Psylloidea, most develop by consuming scale-insects (Coccoidea), either as internal parasitoids, as ectoparasitoids (under the scale), or as predators of their eggs. The males of a number of species develop as hyperparasitoids of coccoids via their eulophid, aphelinid or encyrtid primary parasitoids. A number of aphelinids are internal parasitoids of the eggs of various Auchenorrhyncha, Reduvioidea, Lepidoptera or Orthoptera whilst a very few develop on the larvae or pupae of Dryinidae (Hymenoptera), Cecidomyiidae or Chamaemyiidae (Viggiani, 1984). In Britain, a considerable proportion of the aphelinid fauna comprises species that are primary endoparasitoids of aphids (eg Aphelinus spp.). See Hyatt, M. (1983) The genera of Aphelinidae (Hymenoptera) of the World for a key.

Forty-one species of Aphelinidae are recorded in Britain and Ireland (Dale-SKey et. al, 2016. Checklist of British and Irish Hymenoptera - Chalcidoidea and Mymarommatoidea. Biodiversity Data Journal. 4: e8013), although only one of these is recorded as a parasitioid of British and Irish miners.

All of the parasitoids and their associated host miners listed here occur in Britain (albeit in quaratine or glasshouses only). The associations themselves, however, may not be British.

At present, of the 1,103 British and Irish miners discussed here 363 have no known Hymenoptera parasitoids, although it is likely that most of them are yet to be discovered.

Unless otherwise stated, all parasitoid / host miner associations of Chalcidoidea are extracted from the Universal Chalcidoidea Database by Dr John Noyes.

Clicking a chalcidoid name will search the database and return the synonymy, taxonomy, distribution, associates (both host plants and host insects), biology, economic references and images of that parasitoid.

Clicking on a miner host name will open that species page on this website.
