Abstrakt

The direct contact activity of pyrethroids (alphametrin, deltamethrin, lambdacyhalothrin, zatacypermethrin) and etofenprox was tested against common cockchafer adults and some Lepidoptera (nun moth, pine moth) and Diprionidae larvae and large pine weevil adults. The results of this study showed that common cockhafer adults were more susceptible to the examined pyrethroids than larvae of Lepidoptera and Diprioninae but less susceptoible to etofenprox. The tested pyrethroids were effective against large pine weevil adults at doses 400–500 times higher than those for common cockchafer adults.
