摘　　要：为了探讨滇杨枝把挥发物对马铃薯块茎蛾产卵行为的影响,在室内和模拟仓库内利用选择性产卵试验方法,分别测定了不同质量的萎蔫滇杨枝把的挥发物对马铃薯块茎蛾产卵选择性的影响。结果表明：在实验室内10~80 g的萎蔫滇杨枝把的挥发物对雌蛾的产卵有极显著的抑制作用,在模拟仓库内500~2000 g的萎蔫滇杨枝把挥发物对马铃薯块茎蛾产卵有极显著的抑制作用,并且抑制效果均随着质量的增加而不断增强。Through selective oviposition tests in the laboratory and simulative warehouse, the effects of volatiles from different mass of wilted branches of Populus yunnanensis on the oviposition selectivity of potato tuber moth, Phthorimaea operculella （Zeller） were studied respectively. The results indicated that： in the laboratory, the volatiles from 10 -80 g wilted branches of Populus yunnanensis had very significant inhibitory effect on the oviposition of female moth ; in the simulative warehouse, the volatiles from 500 2000 g wilted branches of Populus yunnanensis had very significant inhibitory effect on the oviposition of this moth ; the inhibitory effect of the volatiles in both the laboratory and the simulative warehouse was continuously enhanced when the mass of wilted branches increased.
