Seasonal incidence of Sap feeders on Sesame (Sesamum indicum L.) and correlation with Abiotic factors

Five sap feeders were observed viz., white fly (Bemisia tahacl), leaf hopper (Orosius abicinctus), green bug (Nezara viridula), lygaeid bug (Aphanus sordidus) and cotton aphid (Aphis gossypii) at different stages of crop growth. The population of whitefly, sesame leaf hopper, green sting bug and cotton aphid were found negatively correlated with minimum temperature, relative humidity and rainfall and positively correlated with maximum temperature in all varieties of sesame viz., Type 4, Type-12, Type-13. Type-78 and Shekhar.
