Abstract


In a search for possible vectors of little cherry disease (LCD) more than 118 aphid species, including 13 new records for B.C., were trapped in yellow-pan water traps set out in Okanagan cherry orchards. Eleven species were trapped more than 250 times. In descending order of occurrence, they were <i>Aphis pomi</i> de Geer, <i>Aphis nasturtii</i> Kaltenbach, <i>Myzus persicae</i> (Sulzer), <i>Pemphigus populivenae</i> Fitch, <i>Aphis citricola</i> van der Goot, <i>Hyperomyzus lactucae</i> (Linnaeus), <i>Capitophorus horni</i> Borner, <i>Metopolophium dirhodum</i> (Walker), <i>Rhopalosiphum padi</i> (Linnaeus), <i>Capitophorus hippophaes</i> (Walker) and <i>Hayhurstia atriplicis</i> (Linnaeus).

Nine species of aphids reproducing on <i>Prunus</i> spp. including A<i>phis pomi</i>, <i>Asiphonaphis pruni</i> Wilson & Davis, <i>Brachycaudus cardui</i> (Linnaeus), <i>Brachycaudus helichrysi</i> (Kaltenbach), <i>Dysaphis plantaginea</i> (Passerini), <i>Hyalopterus pruni</i> (Geoffroy), Myzus cerasi (Fabricius), Myzus persicae, and <i>Rhopalosiphum cerasifoliae</i> (Fitch) failed to transmit LCD to test trees of c.v. Sam.
