采用人工投虫方法,研究了斜纹夜蛾对3种不同波长的诱虫灯的趋向性特点以及夜蛾不同日龄和夜间不同时段对趋光率的影响情况,结果表明:1日龄至5日龄的成虫扑灯率较高,即5日龄以前斜纹夜蛾比较活跃,除2日龄成虫反应率稍低以外,其他各日龄期成虫反应率均在20%以上,而6日龄成虫反应率低于5%。斜纹夜蛾成虫趋光性在夜间时段上的差异表现:在20:00至20:30成虫扑灯总数占整个观察时段的41.57%,也即投虫后0.5h扑灯率达到最高,然后逐渐走低,1h后扑灯率达到最小值,往后又逐渐回升。结果还表明,斜纹夜蛾成虫的趋光性对3种不同波长的光源具有明显的差异性。

　　Using the Method of artificial feeding insects, Spodoptera litura was studied on the effects of phototaxis rate influented by trap lamp of 3 kinds of different wavelengths tend to characteristic, different day-age of S.litura and different night-time.The results showed that : 1 to 5 day-age adults have a higher fluttering light rate, that's to say, S.litura before 5 day-age was more active, and except for 2-day-age adults responsing rate lower, the reaction rate of other day-age adults was above 20%, while the 6-day-old adults got less than...
