2011年在二点委夜蛾成虫发生高峰期内,将几种测具设置在同一生态区域内进行诱集试验,在田间自然条件下证明成虫的趋化、趋味性,从中筛选有效的监测工具。结果表明,二点委夜蛾成虫对糖醋诱杀液有一定的趋性,但效果差,成本高;杨树枝把对二点委夜蛾成虫的诱集效果比麦秸把、半干草堆、麦秸堆理想,诱集数量多,总体效果与佳多测报灯相当;半干草堆和麦秸堆有一定的诱虫效果,但诱测数量与杨树枝把相差太大;竖放的麦秸把基本没有诱测效果。
In 2011, during the peak period of the emergence of the adult worms of the 2nd stage, two kinds of measuring tools were set in the same ecological area to carry out the trapping test, which proved the chemotaxis and tendency of the adults in the field under natural conditions and screened the effective monitoring tool. The results showed that the adults of the 2nd instar Spodoptera litura had a certain tendency to sweet and vinegar trapping solution, but the effect was poor and the cost was high. The effect of poplar branches on the adults of the second instar Spodoptera litura than the straw, semi-hay, wheat straw Heap ideal, the number of traps, the overall effect is equivalent to the good multi-report light; semi-hay and wheat straw reactor has a certain effect of trapping insects, but the amount of the test and the poplar branches too much difference; Test results.
