Message:
Abstract:
In this study, the adult wasps were exposed to fresh residuces of the insecticide. The LC50 value of pyridalil were 2451 ppm. Sublethal effects of pyridalil on life table, reproduction parameters and survivorship of H. hebetor were studied. The survivorship was affected by the insecticide. Life expectancy and Mortality rate were not significantly affected but reproduction parameters of H. hebetor was affected by the insecticide. Mortality of egg and larval stages was significantly affected by the insecticide, but the adult emergence rate was not significantly affected by the pyridalil. Results showed that pyridalil insecticide had less adverse effects on the parasitoid. Field studies aiming to assess efficacy of combined use of insecticide and H. hebetor is needed to obtain more applicable results.
