舞毒蛾性信息素诱捕器应用技术研究

Applied technology of traps with sex pheromone of gypsy moth,Lymantria dispar(L.)

通过对舞毒蛾性信息素诱捕器应用技术研究表明:三角型粘胶板诱捕器、奶盒型诱捕器和圆筒型诱捕器对舞毒蛾的诱捕效果不同,三角型粘胶板诱捕器的诱虫效果最好,圆筒型诱捕器次之;诱捕器设置高度对诱捕效果有明显的影响,设置高度为5.5 m的诱捕器诱捕作用最强,3.5 m次之,1.5 m最差;雄蛾对人工合成信息素的昼夜反应节律发生在白天,从8∶00持续到22∶00,反应高峰在14∶00,反应模式为"单峰式-白天型"。

Using 3 types of sex pheromone traps with 3 different heights to trap gypsy moth,Lymantria dispar,the results showed that the effect of catching gypsy moth with triangular sticky trap,box trap and cylinder trap were different.The effect of triangular sticky trap was the best and cylinder trap was the second.The height of traps had obvious influence on the effect of trapping,and the 5.5 m height trap was the best,followed by 3.5 m and 1.5 m.Diurnal rhythm of male moths on artificial synthetic pheromones occurred in the daytime from 8∶00 to 22∶00,and the reaction peak was at 14∶00 p.m..Thus the reaction mode was single-peak daytime type.
