Author(s): Repalle Naganna and Shinde Cu
Abstract:
The study on relative toxicity of different insecticides against G. nephantidis revealed that there was no insecticide under testing found totally safe except control treatment (water spray) to the adults ofG. nephantidis. However, spinosad 45 SC was comparatively harmless to the adults. Moreover, indoxacarb 15.8 per cent EC, emamectin benzoate 5 per cent SG, quinalphos 25 per cent EC, flubendiamide 39.35 per cent EC and profenofos 50 per cent EC were slightly harmful. Furthermore, triazophos 40 per cent EC, dichlorvos 76 per cent EC and chlorpyriphos 20 per cent EC were moderately harmful, while none of insecticide was categorized as harmful to the adults of G. nephantidis under laboratory conditions.
