Food is the basic human need and producing enough to feed the growing population of developing nations is one of the biggest challenges faced by modern world. Next to wheat rice is one of the top most food grain consumed worldwide. Rice production plays a major role of the national agricultural economy of India. India holds the second position in rice production of all over the world. International Rice Research Institute (IRRI) finds that on average, farmers lose 37 percent of their rice yield to pest and diseases. In India the annual crop losses due to insect pests and diseases are about 38 percent. Worldwide more than 100 species of insects are recorded in rice production, out of which about 20 species cause significant economic damage amongst various pests affecting the paddy crop. The yellow stem borer (Scirpophaga Incertulas) contributes 90 percent of damage in the paddy field, especially during the rainy season. The four different methods are generally practiced to control yellow stem borer are cultural control, varietal resistance, chemical control and biological control. The chemical control method may contribute to decline in wildlife and create harmful impact on human health; through the biological control method the pest can be controlled by stirring up other living organisms. The biological control method helps to destroy only the harmful pests and it does not affect any beneficial insects like a human being. Hence this study was taken up and its result will be useful for scientist’s to work out for a biological control to support the ultimate beneficiary of the farming community.
