Abstract

Laboratory studies were conducted to determine the toxicity of a number of insecticides to adults of the carrot weevil, Listronotus oregonensis (LeConte). Initial screening tests indicated that, in general, carrot weevil adults were quite tolerant to insecticides. However, several materials showed sufficient activity as direct contact, residual contact-stomach, and soil insecticides to warrant testing under field conditions. These included Zinophos® (O,O-diethyl 0–2 pyrazinyl phosphorothioate), WL 24073 [O-(2-chloro-l-(2,5-dichlorophenyl)vinyl) O-methyl ethylphosphonothioate], WL 25735 [O-(2-chloro-1-(2,5-dichlorophenyl) vinyl) O-methyl methylphosphonothioate], Pirimiphos-methyl® (O-[2-(diethylamino)-6-methyl-4-pyrimidinyl] O,O-dimethyl phosphorothioate), tetrachlorvinphos, and parathion. Although less active, Biothion® [(O,O′-thiodi-p-phenylene) O,O,O′,O′-tetramethyl phosphorothioate], carbofuran, and chlorpyrifos were also considered sufficiently effective to warrant further study.

Des essais en laboratoire ont été menés pour déterminer la toxicité d’insecticides contre l’adulte du charançon de la carotte, Listronotus oregonensis (LeConte) par contact direct, par contact et ingestion et par application au sol. Les tests d’élimination préliminaire par contact direct ont montré que 28 des 45 insecticides étaient plus toxiques que le DDT. La majorité des insecticides se sont avérés plus efficaces par contact et ingestion. L’efficacité de certains insecticides prometteurs a été réduite par application au sol. Plusieurs insecticides ont démontré une activité assez grande pour être essayés en plein champ. Parmi ceux-ci, l’on retrouve Zinophos, WL 24073 [O-(2-chloro-1-(2,5-dichlorophenyl) vinyl) O-methyl ethylphosphonothioate], Pirimiphos-methyl® (O-[2-(diethylamino)-6-methyl-4-pyrimidinyl] O,O-dimethyl phosphorothioate) et parathion.
