Studies were conducted on seasonal incidence of Scirtothirps dorsalis H. during the year 2013-2014 at the University Research Farm, Sher-e-Kashmir University of Agricultural Sciences and Technology-Jammu. The incidence of thrips, S. dorsalis was 4.31 thrips leaf-1 plant-1 in the 14th standard week and reached its maximum 13.98 thrips leaf-1 plant-1 in the 48th standard week. The mean maximum temperature and relative humidity (morning) had negative effect with “r” values (r = -0.112 and -0.046). The mean minimum temperature, relative humidity (evening) and rainfall had highly negative significant effect on thrips population. The relative efficacy of insecticides against the thrips, S. dorsalis showed that imidacloprid 200SL (0.0025%) was the most effective followed by, dimethoate 30EC (0.05%). The least effective insecticide against thrips was neem oil (0.05%).
