Abstract:
In laboratory experiments, chlorpyriphos 20 EC was safer to adults of Cryptolaemus montrouzieri Mulsant at 500 and 250 ml/ha and was slightly harmful to Cheilomenes sexmaculata Fabricius. Lower doses were comparatively safer to grubs and adults of C. montrouzieri. Lower mortality was observed in chlorpyriphos 20 EC 250 ml/ha (33.33%) followed by chlorpyriphos 20 EC 500 ml/ha (36.67%) and Dursban 20 EC 500 ml/ha (40.00%) after 48 hours of treatment. Low adult mortality was observed by chlorpyriphos 20 EC 250 ml/ha (36.67%) followed by chlorpyriphos 20 EC 500 ml/ha (40.00%) and Dursban 20 EC 500 ml/ha (43.33%). Mortality of C. sexmaculata grubs and adults were, 56.50 to 80.00 per cent and 61.50 to 82.50 per cent respectively.
