The study was undertaken during 2011 and 2012 in five tehsils of Nimar region (West Madhya Pradesh) around the Narmada river, namely-Sanawad, Badwani, Khargone, Maheshwar and Dhamnod to know the over dosing trend and adverse effect of insecticides against sucking insect pest of cotton. In each location ten farms of different categories were selected based on acre age as F-1(up to 02 acres), F-2 (up to 04 acres), F-3 (up to 06 acres), F-4 (up to 08 acres), F-5 (up to 10 acres), F-6 (up to 12 acres), F-7 (up to 14 acres), F-8 (up to 16 acres), F-9 (up to 18 acres) and F-10 (More than 18 acres). All the information about insecticidal applications was received through discussion with farmers. The received information by each farmer of same category of ten locations about applied dose of insecticides and per cent reduction in insect population in each spray was averaged. The averaged data about insecticidal dose was converted into per cent increase over recommended dose of each insecticide and tabulated. The higher dose of acetamiprid 20 SP imidacloprid 17.8 SL,  thiamethoxam 25WG, monocrotophos 36 SL,  thiacloprid 21.7 SC  and diafenthiuron 50WP was 36.01,45.89%, 64.61%, 72.10%, 79.24% and 85.60% in first, second, third, fourth, fifth and last spray, respectively. The reduction in insect pests population was found 55.40-72.40%, 52.50-60.50% , 51.25-58.25% 57.20-66.65% 50.75-63.25% and 55.40-68.25%% in first, second, third, fourth, fifth and last spray, respectively and overall averaged as 57.76-62.22%. From all the observations it was concluded that the application of higher dose of any insecticide did not reduce the sucking pest population much more than the recommended dose.
