用主成分分析并绘制二维排序图，发现水稻二化螟、茭白二化螟交迭在一体。

Two dimension distribution figure was drawn by principal component analysis, which revealed that the striped stem borers overlapped.

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。

SSB from both rice and Zizania fields mostly prefer to oviposit on Zizania plants.

养蟹稻田二化螟和三化螟螟害率是常规非防治稻田的2—3倍，甚至更高；

The damage of Chilo suppressalis and Tryporyza incertulas was about 2-3 times of that in monoculture paddy-field and even more;

通过对茭白二化螟的越冬习性、产卵习性、钻蛀及转移规律，田间种群动态、天敌种类进行了调查和研究。

This paper dealt with the overwintering, oviposition, boring and transferring behavior, population dynamics, and control of striped stem borer (SSB), Chilo suppressalis in Zizania fields.
