The field experiments were conducted during Kharif season of 2016-17 and 2017-18 at the Research Farm of Department of Agricultural Entomology, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to study the influence of cliamatic condition on thrips population on chilli cv., PBNC-1in non-replicated design. The incidence of thrips Scirtothrips dorsalis (Hood), initiated from 34th Standard Meteorological Week (0.60 thrips/leaf) and 35th SMW (0.10 thrips/ leaf) and increased gradually to reach its peak in 43rd SMW (12.36 thrips/leaf) and 47th SMW (9.86 thrips/ leaf) during 2016-17 and 2017-18 respectively. As regard the correlation studies, rainfall had significant and negative correlation (r=-0.415*) and maximum temperature significant positive correlation (r= 0.361*) with the incidence of thrips suggesting significance of these parameters in population of thrips.
