Aphid parasitoids in the Cape Verde Islands (Hymenoptera, Aphelinidae, Aphidiidae)

Resumen

The rearing of various aphid species on various plants yielded three pnmary parasitoids: Aphelinus sp., Aphidius colemani Vier. and Diaeretiella rapae (M’Intosh). Both aphidiid species are broadly oligophagous. Faunal relationships show Afro-tropical features. The parasitoid spectmm was found specifically poor in relation to 29 aphid species known to occur in Cape Verde Islands. Severa1 parasitoids species are recornmended to be introduced in a biocontrol programme.
