Abstract:
Sunflower is an important oilseed crop in India. Sunflower crop was mainly attacked by more than fifty different insect pest but in this on going study only defoliator and capitulum borer insect was considered and an effort has been made to control these insect incidence by use of biological measures i.e., influence of predators on defoliator and capitulum borer along with weather parameters for six consecutive cropping years. R², Adjusted R² and Root Mean squared Error value were used to determine best fitted model. In all the six years there was influence of predators and weather parameters on Defoliator and capitulum borer.
