几种诱杀法对烟仓烟草粉螟成虫的防治效果

Control Effect of Different Trapping Methods on Adults of Ephestia elutella in the Tobacco Barn

为有效控制烟草粉螟对储藏期烟叶的危害,采用灯光诱捕法和性信息素引诱法,对烟草粉螟成虫的室内实仓诱集效果进行了研究。结果表明:灯光诱杀3种诱捕光源以频振式杀虫灯的诱集效果最佳,白炽灯次之,荧光灯诱集效果最差;粘胶纸板和水盆诱捕(洗衣液)2种性信息素诱捕法对烟草粉螟均具有较高的诱集效果;性信息素诱芯在室内25℃放置30d后对烟草粉螟仍具有一定的诱集效果。结论:当烟仓烟草粉螟虫口密度较低时,粘胶纸板法可对其起到较好的控制效果,而在其高发期,性信息素引诱以水盆诱捕法(洗衣液)最具实用价值。

The trapping effect of light trapping method and sex pheromone trapping method on adults of E. elutella in the tobacco barn was studied to effectively control E. elutella. The results showed that the trapping effect of three light trapping methods was frequency-changing light ） incandescent light~ fluorescent light and two sex pheromone methods both had higher trapping efficiency. The sex pheromone lure still had a certain trapping effect in the tobacco barn at 25 C after 30 d. When the insect population of E. elute[la adult was low, the method of the mucilage glue cardboard with sex pheromone had the better control effect on E. eZutella adults. Whereas, when the insect population was high, the method of the laver with washing powder water and sex pheromone had the optimal practical value.
