abstract
An experiment was carried out to determine the comparative toxicity of insecticides and bio-pesticides against Menochilus sexmaculatus Fab. in laboratory after different intervals 24, 48, 72, 96 and 120 hours, in the Department of Entomology, Faculty of Crop Protection, S.A.U Tando Jam during 2015. Life stages of predatory beetle treated with insecticide Curacron (Profenophos) in which egg and adult stages not survived, however, the immature stages of 1^st, 2^nd, 3^rd and 4^th instar larva survived. Egg and adult stages were not survived after application of Novastar insecticide, therefore, 1^st, 2^nd, 3^rd and 4^th instar survived. It was observed that the highest survival was recoded in egg stage after 24 hours, after exposure of bio-pesticide Hazropattar (Tobacco extract). The highest survivor was recorded in the 4^th instar followed by 3^rd, 2^nd and 1^st instar larvae from 24 to 120 hours, respectively after exposure of bio-pesticide of Balkhi (Tobacco extract). It is concluded that insecticides i.e. Curacron and Novastar were found toxic, whereas, bio-pesticides i.e. hazropattar and Balkhi showed least toxicity against M. sexmaculatus.
