摘要：

为研究大连地区玉米螟越冬期间气象条件对越冬后活虫数的影响，以期为防治玉米螟提供科学依据。利用大连地区最近10年气象资料和玉米螟越冬后活虫数资料，对玉米螟越冬后活虫数与越冬期间气象要素进行相关性分析。结果表明，玉米螟冬后百杆活虫数受上年10月下旬—11月份温湿条件影响较大。此间温度低有利于其越冬成活；11月份降水多，冬后百杆活虫数多。建立大连地区玉米螟冬后百杆活虫数统计预报模式。

Abstract:

In to analyze the effect of the meteorological conditions in winter on the number of live corn borers after the winter in Dalian area, so as to provide scientific basis for prevention and treatment of the corn borers. Based on the recent 10-year meteorological data and the number of live corn borers after the winter in Dalian region, the correlation between the number of live corn borers after winter and the meteorological elements during the winter was analyzed. The results indicated that the number of corn borers after winter was significantly influenced by the meteorological conditions from late October to November. Low winter temperatures did conducive to their survival. More precipitation was beneficial to the increase in the number of live borers, in November. Established the statistical forecasting models of corn borer live pests after winner in Dalian region.
