摘      要：Rice leaffolder,Cnaphalocrocis medinalis(Guenée),has become a major pest throughout the rice cultivating areas of China and caused severe damage to rice *** medinalis granulovirus(CnmeGV),a naturally occurring baculovirus,is revealed as a potential microbial agent for the pest *** applications of CnmeGV were conducted against rice leaffolder larvae in rice *** infected the larvae not only in the current generation but also in the successive generation,resulting in a sustained infection in the larva population for at least 48 *** diferent concentrations of CnmeGV(7.5×1011 and 1.125×1012 occlusion body(OB)ha-1)at 30 days after spraying,larval population reduced up to 76.32%and rice leaf rolled rate kept in 15.42%.Simultaneously,CnmeGV had no impact on arthropod predators of ***,with abundances ranging from 2.39 to 3.79 per ten *** results revealed that CnmeGV is suitable as a bio-pesticide for rice leaffolder management in rice paddies.
