| Summary: | The effects of five insecticides namely chlorpyrifos, dichlorvos, malathion, permethrin and pirimiphos-
methyl was tested in vitro on the six larval instars of Corcyra cephalonica St. Based on the LCs 0
values, the order of susceptibility of the different larval instars was 2>1>3>4>5>6while for
dichlorvos it was 1>2>3>4>5> 6. The order for malathion, permethrin and pirimiphos-methyl
was 1>2>3>4> 6>5. The order of relative toxicity of the five insecticides was dichlorvos >chlorpyrifos
>permethrin >pirimiphos-methyl >malathion for the second to the fifth instar, while for the
first and sixth instar it was dichlorvos >pirimiphos-methyl > malathion for the second to the fifth
instar, while for the first and sixth instar it was dichlorvos >pirimiphos-methyl >permethrin >chlorpyrifos
> malathion, and dichlorvos > permethrin > chlorpyrifos > pirimiphos-methyl > malathion,
respectively. I!.ichlorvos is recommended to replace malathion for the control of certain species of stored preduct
pests. |
