Influence of weather parameters on seasonal incidence of chilli thrips (Scirtothrips dorsalis hood) on chilli

The thrips incidence was initially recorded as 4.00 thrips/3 leaves after 2nd week of transplanting of chilli seedling (44th SMW). Which gradually increased and reached to it’s peak (10.40 thrips/3 leaves) after 7th week of transplanting (49th SMW) their after thrips population decrease and remained active up to 22nd weeks after transplanting (12th SMW) with an average population 2.66 thrips/3 leaves. Correlation of thrips population with weather parameters revealed that maximum temperature, minimum temperature and rainfall showed negative correlation (r = -0.2397, -0.1369 and -0.0198, respectively) while, morning relative humidity and evening relative humidity was positively correlated (r = 0.4480 and 0.2342, respectively).
