Abstract

The contact toxicities of 11 insecticides were determined with a Potter spray tower using adults of crucifer flea beetles (Coleoptera: Chrysomelidae) collected from three locations over a 3-year period. Flea beetles collected from an experimental farm at London, Ontario, where no insecticides had been used, were compared with those from canola-growing areas near Saskatoon, Saskatchewan, and Winnipeg, Manitoba. Lindane, in a seed dressing, is widely used in both Saskatchewan and Manitoba whereas carbofuran, as in-furrow granules, has been more heavily used in Manitoba than in Saskatchewan. The flea beetles from Winnipeg were significantly less susceptible to all three carbamates tested (carbofuran, carbaryl, oxamyl) than those from Saskatoon or London. Both the Winnipeg and Saskatoon flea beetles were significantly less susceptible to methamidophos than the London population but not to the other organophosphates, the organochlorine (endosulfan), or the pyrethroids that were tested. These differences may indicate resistance in the Manitoba population, but this low level would not affect the efficacy of the currently recommended insecticides. The results emphasize the need to develop control strategies that will minimize the chances that the level of resistance will increase.

Résumé

La toxicité de 11 insecticides de contact a été mesurée par vaporisation au moyen d’une tour Potter sur des adultes de l’Altise des crucifères (Coleoptera : Chrysomelidae) récoltés en trois endroits au cours d’une période de 3 ans. Les altises récoltées dans une ferme expérimentale à London, Ontario, où aucun insecticide n’a été utilisé, ont été comparés à des altises provenant de régions productrices de colza près de Saskatoon, Saskatchewan, et de Winnipeg, Manitoba. Le lindane, dans une préparation appliquée aux graines, est utilisé couramment aux deux endroits, alors que le carbofurane, sous forme de granules déposés dans les sillons de labour, a été utilisé surtout au Manitoba. Les altises de Winnipeg étaient significativement moins sensibles aux trois carbamates utilisés (carbofurane, carbaryl, oxamyl) que les altises de Saskatoon ou de London. Les altises de Winnipeg et de Saskatoon étaient significativement moins sensibles au méthamidophos que la population de London, mais elles n’étaient pas moins sensibles aux autres organophosphates, à l’insecticide organochloré (endosulfane), ou aux pyréthroïdes. Ces différences sont peut-être attribuables à l’apparition d’une résistance chez la population manitobaine, mais cette légère diminution de la sensibilité n’affectera pas l’efficacité des insecticides couramment utilisés. Ces résultats soulignent l’importance d’élaborer des stratégies de lutte qui puissent minimiser la probabilité d’une augmentation de la résistance.
