Abstract
Insect pests are the major constraints in enhancing rice productivity, besides diseases and weeds. They cause 20-30 per cent losses every year. More than hundred species of the insects have been reported attacking the rice crop and 20 of them can cause serious economic loss. Rice stem borers have acquired the status of regular insect pests of rice in most of the rice grown area in the state. Five species in families, crambidae and noctuidae of Lepidoptera have been reported as important stem borer pests of the rice in India. Of these, yellow stem borer, Scirpophaga incertulas is the dominant species across the country. It can be effectively managed by adopting IPM practices including cultural, mechanical, biological and chemical control.
