Abstract

Seasonal incidence of sesame pod bug, Elasmolomus sordidus was studied by taking fortnightly sowing in 20 m plots. The bug population was abundant and caused maximum damage during the month of October to November and August to September and absent during the month of January and February. The correlation analysis showed that only the minimum temperature and the R.H. were highly and positively correlated with the sesame pod bug incidence on sesame. The regression analysis indicated that while the maximum temperature had negative influence on the bug incidence, the minimum temperature had a positive regression coefficient which predicted that every one degree of minimum temperature increase in the pest population to the tune of 1.704 insects.
