摘要: 测定了棉铃虫Helicoverpa armigera处女雌蛾和交配雌蛾对小麦花中单一或多个挥发性物质的EAG反应。在单组分或多组分的测定中,棉铃虫处女蛾和交配蛾在P=0.05水平上并不存在显著性差异,但在混合的绿叶气味物质中加入含量为1×10-5~5×10-5(体积比)的正庚醛时,交配蛾对混合物的触角电位反应显著高于处女蛾的反应(P<0.05)。

Abstract: Electroantennogram (EAG) responses of female Helicoverpa armigera (Hübner) to the single or mixture of volatile components of the wheat blossom were examined. For single compound or mixture compounds, there were no significant differences between EAG responses of virgin females and mated females (P=0.05). But, when heptanal was added in different concentrations of 1×105-5×105(V/V) to the mixture of greenleaf volatile compounds, the respondence of the antenna of mated female of cotton bollworm to the mixture of compounds was significantly higher than that of the virgin female (P<0.05).

Key words: Helicoverpa armigera; female moths, host-plant volatile compounds, heptanal, electroantennogram
