二化螟是我国水稻上一种重要的钻蛀性害虫，以幼虫滞育越冬。通过对宜春地区水稻二化螟越冬幼虫基数的调查与第1代成虫发生期的监测，结果表明：不同县市区的二化螟越冬基数差异较大，总体趋势显示丘陵山区高于平原滨湖区。在两种区域都显示机械收割田块二化螟的越冬基数高于手工收割。第1代二化螟成虫监测显示，丘陵山区二化螟的发生期比平原滨湖区明显推迟，并且丘陵山区和平原滨湖区二化螟越冬代成虫的羽化都有明显的多峰型羽化特点。

The rice stem borer, Chilo suppressalis, overwintering as larva, is one of the serious pests of rice in China. The over-wintering cardinal larvae number of the rice striped borer Chilo suppressalis was investigated and the emergence of the 1st generation adults was monitored in Yichun City, Jiangxi Province. The results showed that the over-wintering cardinal larvae numbers were quite different between different county and district. However, the trend showed that the over-wintering cardinal larvae numbers in hilly areas were higher than that in plain-lake regions. And between the mechanical harvesting fields and manual harvestings fields, the former had a higher over-wintering cardinal larvae number. Using the light trap monitors, the adults emergence dynamics of the 1st generation Chilo suppressalis were recorded, and the results showed that the peak occurrence period in the hilly areas was significantly delayed than that in the plain-lake regions. While the adults’ emergence pattern in both the hilly mountainous areas and plain-lake regions had characteristics of multi-peak eclosion.
