咖啡木蠹蛾在福建省 1年发生 2代 ,幼虫的孵化高峰期分别发生在 6月与 10月 ,掌握其幼虫孵化高峰期适时喷施 2 0 %三唑磷乳油 15 0 0倍稀释液 ,结果表明 ,对药前 10 d内孵化已蛀枝干的幼虫杀虫率为 90 %～ 10 0 % ,对药后 10 d内已蛀枝干的幼虫杀虫率为 85 %～ 10 0 % ,2次施药就能有效防治咖啡木蠹蛾为害。由于此法简便 ,经济 ,易行 ,故建议在生产上可以推广应用。
Zeuzera coffeae Nietiner has 2 generations each year in Fujian province. The hatching peak of the larvae was June and October respectively. During the hatching peak of the larvae,using 1500 times dilution of 20% triazophos to control the larvae, the results showed that the mortality of the larvae having eaten into the stem ten days before and ten days after using the petislide was 90-100% and 85-100% respectively.
