Abstract

In 1986 a greenhouse population of Liriomyza trifolii (Burgess) was shown to be highly resistant (155-fold at LC50) to the organophosphorus compound pyrazophos. However in 1987, the same population had only 35–40% resistant individuals remaining. A survey in 1986 of five other greenhouses reporting leafminer control failures indicated three other resistant populations in southern Ontario. Resistance was not affected by the addition of the synergists diethyl maleate or triphenyl phosphate to pyrazophos. Cross-resistance to the phosphorothioate insecticides demeton, chlorpyrifos, and triazophos was indicated.

Résumé

En 1986, on a découvert qu’une population en serre de Liriomyza trifolii (Burgess) était très résistante (155 fois à la CL50) à l’insecticide organophosphoré pyrazophos. Cependant en 1987, il ne restait seulement que 35–40% d’insectes résistants dans la population. En 1986, une enquête auprès de cinq autres serres où l’on avait signalé une lutte inefficace contre les mineuses a révélé la présence de trois autres populations résistantes dans le sud de l’Ontario. L’addition de produits synergiques comme le maléate de diéthyle ou le phosphate de triphényle au pyrazophos n’a pas eu d’effet sur la résistance. On a signalé une résistance croisée aux phosphorothioates déméton, chlorpyrifos et triazophos.
