ABSTRACT Fi ve specics are aducd to th e aphid fa un a of British Colu mbia. Fifty-four of th e SlI new aph id -host plant as sociations of plant specics arc new host plants. INTRODUCTION Four hundred spec ies of aphids coll ected from I 124 hosts or in traps, and 2233 aphid-host plant associations were recorded in fift een previous li sts of th e aphids of British Colu mbia (Forbes. Frazer and MacCarthy 1973; Forbes. Frazer and Chan 1974: Forbes and Chan 1976. 197R , 1980, 198 1, 1983, 1984, 1985, 1986a, 1986b, 1987, 1988, 1989: Forbes, Chan and Foottit 1982). T he present li st adds 5 aphid species (indicated with an asteri sk in (he li st) and 88 aphid-host plant associati ons to the previous li sts, Fifty-four of the new aphid-host plant associati ons of plant species have not been recorded before. The additi ons bring the Ilumber of kn own aphi d species in British Columbia to 405. Aphids have now been coll ected from 11 78 different host plants and the total nlllnber of aphi d­ host plant associations is 232 1. J. E'JIOMOI. S()c. B RIl . COII ''1 BIA XX.

The aphid names are in conformity with Eastop and Hille Ris Lambers (\ 976) and are listed alphabetically by species, except that Aphis cilrico/a van der Goot has been restored to its former name, Aphis spiraeco/a Patch, based on the findings of Eastop and Blackman (1988). Names of native host plants are based on Anonymous (1982) and Taylor and MacBryde (1977). Names of cultivated host plants are based on Anonymous (1976). Fifty-one new collection sites are given in Table I. The reference points are the same as those shown on the map which accompanies the basic list (Forbes, Frazer and MacCarthy 1973). Most of the aphids were collected by the authors except the Cinara spp. were Foottit's (1987) collections.
