摘要: Abstract Lethal and sublethal effects of imidacloprid buprofezin on preimaginal adult stages the cotton whitefly parasitoid Encarsia inaron (Walker) (Hymenoptera: Aphelinidae) were investigated in laboratory. Both insecticides significantly reduced emergence when parasitised nymphs, at either larval or pupal stages, treated with field-recommended concentrations. Buprofezin had no significant effect wasps. The LC 50 value for E. inaron was 208.9 ppm. Adult longevity total progeny number affected only by larvae treated. a influence daily fecundity depending stage time treatment. Sex ratio offspring insecticides. Some life history parameters application stages. However, neither table adults. implications these results integration biological chemical control methods are discussed.
