Abstract
The lupine aphid, Macrosiphum albifrons Essig, occurs throughout southwestern 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 secondo-, 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.
