摘  要:
Since 2003 the damage by C.medinalis has been increasing with such characteristics as a large number of the immigrants,a long immigrating time,an earlier time in peak period and a heavy damaged loss in field rice.The past control measures have not effectively controlled the damage by C.medinalis.The experiments showed that changing the control period from the peak period of the 2nd instar larvae to the full egg stage and meanwhile applying quick-acting pesticides and persistent pesticides could control C.medinalis,and the control efficiency could be stably above 90%.
