Lupine aphid, Macrosiphum albifrons (Homoptera: Aphididae): Distribution and hymenopterous parasites in British Columbia
Environmental Entomology 15 (3), 719-722
Abstract: The lupine aphid, Macrosiphum albifrons Essig, occurs throughout south-western British Columbia on Lupinus arcticus S. Wats, and L. polyphyllus Lindl., and less frequently on L. sericeus Pursch. It is parasitized by four species of Aphidiidae: Aphidius lupini Liu, Ephedrus californicus Baker, and two unidentified species of Praon. Percentage of parasitism varied seasonally and between collecting sites. A. lupini was the most common and widespread parasite; it killed an average of 5.2, 7.6, and 9.0% of second-, third- and fourth-instar aphids, respectively, over the season as a whole. A fungal pathogen, Entomophthora sp., caused ca. 60% mortality among third- and fourth-instar aphids during rainy periods in late spring and late summer. A. lupini is considered as a potential agent for biological control of the lupine aphid in England.
