In pear and sweet cherry orchards near Creston, in the Kootenay Valley of British Columbia, populations of psyllids, aphids, thrips and leafhoppers were sampled by yellow, and white, sticky board traps hung in the trees. The psyllids were adult Psylla pyricola Först., caught in pear trees; the other insects were caught in cherry trees. The latter insects were: alate Myzus cerasi (F.), adults and nymphs of Taeniothrips sp., and adult leafhoppers of the following species: Edwardsiana rosae (L.), Macrosteles fascifrons (Stål), Psammotettix lividellus (Zett.), Dikraneura absenta DeL. and C., Scaphytopius acutus (Say), Osbornellus borealis DeL. and Mohr., Neokolla hieroglyphics (Say), and Erythroneura spp. Identifications were made by the Systematics and Biological Control Unit of the Canada Department of Agriculture, Ottawa.
