Species compositions of rice stem borers in different rice cultivation system under north Bihar condition

Kumbhar CR and SPN Singh

As the stem borers are harmful pest for rice crop it is very important to know the dominant species population to management of these pest. In order to determine the population dynamics of harmful stem borer to develop ecological and economical viable strategies, a field experiment was conducted at the Research Farm, RPCAU pusa and in the Laboratory, Department of Entomology, RPCAU, Pusa. Results pertaining to the species composition of four species of stem borer of rice viz. yellow stem borer (Scirpophaga incertulas) Walker, pink stem borer (Sesamia inferens) Walker, white stem borer (Scirpophaga innotata) Walker and dark headed striped borer (Chilo polychrysus) Meyrick were prevalent during the crop season. However, yellow stem borer was found to be dominant over other species of stem borer and showed consistency with higher population (92.70 to 93.50, 91.22 to 92.10, 94.00 to 95.17% and 89.10 to 90.00%) in the entire four cultivation system viz. transplanting, drum seeded, direct seeded and SRI (System of Rice Intensification) during Kharif, 2016 and 2017, respectively.
