Seasonal incidence of sesame pod bug, Elasmolomus sordidus was studied by taking fortnightly sowing in 20 m plots. The bug population was bundant and caused maximum damage during the month of October to Nvember and August to September and absent during the month of January an February. The correlation analysis showed that only the minimum temerature and the R.H. were highly and positively correlated with the sesae pod bug incidence on sesame. The regression analysis indicated that hile the maximum temperature had negative influence on the bug incidece, the minimum temperature had a positive regression coefficient which pedicted that every one degree of minimum temperature increase in the pestpopulation to the tune of 1.704 insects.SMV24-09
