摘  要：
为了筛选非寄主植物滇杨的挥发物中驱避马铃薯块茎蛾产卵的活性成分,在室内利用选择性产卵试验方法分别测定了8种挥发物:丁香酚、苯甲酸、苯甲醇、苯乙醇、2-羟基苯甲醛、β-紫罗兰酮、水杨酸甲酯、苯甲醛不同浓度(0.75~12mg/L)的溶液对马铃薯块茎蛾产卵选择的影响。结果表明:水杨酸甲酯在6~12mg/L浓度范围内对马铃薯块茎蛾产卵有极显著的引诱效果。丁香酚在3~12mg/L浓度范围内对产卵有驱避效果,12mg/L时的产卵驱避率为62.1%。苯甲酸在1.5~12mg/L浓度范围内对产卵有驱避效果,但各浓度下的产卵驱避率不存在显著差异。12mg/L的苯甲醇和苯乙醇的产卵驱避率分别为12.1%和20.2%。6mg/L和12mg/L的2-羟基苯甲醛的产卵驱避率分别为44.1%和33.2%。β-紫罗兰酮在1.5mg/L浓度时产卵驱避率为30.9%。12mg/L的苯甲醛产卵驱避率为38.5%。本文测试的8种挥发物中有7种在不同浓度范围内表现出显著的产卵驱避效果。

摘  要：
In order to screen the oviposition repellent from non-host plant volatiles of Populus yunnanensis for Phthorimaea operculella,the effects of eight non-host plant volatiles(eugenol,benzoic acid,benzyl alcohol,phenylethyl alcohol,2-hydroxy-benzaldehyde,β-ionone,methyl salicylate and benzaldehyde)at the concentrations from0.75 mg/L to 12 mg/L on the oviposition choices of P.operculella were tested in the laboratory.The results showed that methyl salicylate at the concentrations from6 mg/L to 12 mg/L had an extremely significant attractive effect on oviposition.Eugenol at the concentrations from~3 mg/L to 12 mg/L extremely repelled oviposition,and the oviposition-repelling percentage at the concentration of 12 mg/L was 62.1%.Benzoic acid at the concentrations from1.5 mg/L to 12 mg/L exhibited extremely repellent activity on oviposition,but their oviposition-repelling percentage had no significant difference.The oviposition-repelling percentage of benzyl alcohol and phenylethyl alcohol at the concentration of 12 mg/L were 12.1% and20.2%,respectively.The oviposition-repelling percentage of 2-hydroxy-benzaldehyde at the concentrations of 6 mg/L and12 mg/L were 44.1% and33.2%,respectively.β-ionone at the concentration of 1.5 mg/L resulted in a repellent effect of 30.9% on oviposition.Benzaldehyde at the concentration of 12 mg/L had a significant repellent effect,and its oviposition-repelling percentage was 38.5%.Seven of the eight tested volatiles showed repellent activity to the oviposition of P.operculella at different concentration ranges.
