Ga. Evans et al., A NEW SPECIES OF APHELINUS (HYMENOPTERA, APHELINIDAE) THAT PARASITIZES THE SPIREA APHID, APHIS-SPIRAECOLA PATCH (HOMOPTERA, APHIDIDAE), Proceedings of the Entomological Society of Washington, 97(1), 1995, pp. 17-21
A new species of an aphid parasitoid, Aphelinus spivaecolae Evans and
Schauff (Hymenoptera: Aphelinidae) is described and figured. This spec
ies is parasitic on the spirea aphid, Aphis spiraecola Patch, and is b
eing investigated for possible use in a biological control program aga
inst the spirea aphid and other citrus aphids including the brown citr
us aphid, Toxoptera citricida (Kirkaldy). The new species is very simi
lar to Aphelinus gossypii and characters to differentiate it from rela
ted species are given.
