水稻田越冬代二化螟最早于4月26日开始羽化，其羽化始盛期为5月9～10日，高峰期为5月13～14日，盛末期为5月18～19日。茭白田越冬代二化螟的始见蛾日为5月5日，比水稻田二化螟迟了9 d，羽化始盛期、高峰期、盛末期依次为5月11～12日，17～18日和23～24日，均比水稻田二化螟迟2～5 d。水稻田二化螟越冬幼虫的存活率和化蛹率分别为67.30%和70.06%，茭白田二化螟则分别比其低20.90%和21.69%；二者的羽化率差不多，分别为90.28%和89.19%。水稻田二化螟羽化成虫的雌雄性比为1∶1.44，而茭白田二化螟则接近1∶1。产卵选择性试验结果表明，水稻田和茭白田二化螟均喜在茭白植株上产卵。

The over-wintering striped stem borer (SSB),Chilo suppressalis (Walker),collected from rice fields started to emerge on April 26.Then 16%,50% and 84% of adults emerged during May 9-10,May 13-14 and May 18-19 respectively.The SSB collected from Zizania fields firstly emerged on May 5,9 days later than those collected from rice fields.The survival and pupation rates of over-wintered SSB collected from rice field were 67.30% and 70.06%,much higher than SSB collected from Zizania fields.The emerging rates were similar between SSB collected from both habitats.The sex ratios of female-male SSB from rice and Zizania fields were 1∶1.44 and close to 1∶1 respectively.SSB from both rice and Zizania fields mostly prefer to oviposit on Zizania plants.
