Selective Toxicity of some Insecticides against Tobacco Aphid, Myzus nicotianae Blackman and its Predator, Cheilomenes sexmaculata (Fabricius)
Studies were conducted to assess toxicity of promising insecticides against tobacco aphid, M. nicotianae and its predator, C. Sexmaculata during 1995 at the Agricultural Research Station, Nipani (Karnataka). The selectivity ratio of M. nicotianae and C. sexmaculata grubs and adults was lowest for acepbate followed by imidacloprid and oxydemeton methyl. However, endosulfan registered highest selectivity ratio and it could be used for aphid control along with the coccinellids in an integrated approach.
