Abstract
AbstractIn 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.
