通过气象因子与落叶松毛虫(Dendrolimus superans (Butler))产卵量及卵孵化率的相关分析和对比分析,确定了影响阿尔山地区落叶松毛虫产卵和卵孵化的关键期及关键气象因子,并采用多元回归方法建立产卵量预测模型.结果表明,阿尔山落叶松毛虫繁殖的关键时期是4月下旬至6月下旬,影响繁殖最显著的气象因子是温度、降雨量和相对湿度.阿尔山落叶松毛虫上树初期(4月下旬至5月上旬)高温少雨会明显降低其产卵量,落叶松毛虫上树到化蛹期(5月上旬至6月下旬)中雨以上降雨时间及降雨量多也会明显降低落叶松毛虫产卵量及卵孵化率.说明气象因子不仅影响当代落叶松毛虫繁殖,而且还影响翌年春季落叶松毛虫幼虫基数及发生趋势.

The key meteorological factors and key periods that determine spawning and egg incubation of Dendrolimus superans in Aershan area were studied through correlation analysis and comparative analysis between meteorological factors and fecundity, egg hatching rate of D. superans. A prediction model of spawning quantity was established by multiple regressions. Results show that the key period influencing the reproduction of D. superans is from late April to late June and the key meteorological factors are temperature, rainfall and relative humidity. In the early period of D. superans up the tree (during the late April and early May), high temperature and little rain would reduce the fecundity of D. superans significantly, and from the period up the tree to the pupation period (during the early May to late June), increasing number of days with moderate rain and much rainfall would significantly reduce the fecundity and egg hatching rate of D. superans. It can be concluded that the meteorological factors influence not only the reproduction of D. superans, but also the cardinal number of D. superans larvae and its occurrence trend for the next spring.
