中文摘要:
      黏虫Mythimna separata (Walker)是一种重要的季节性、远距离迁飞害虫, 近些年在我国的发生有明显加重的趋势。本试验运用电生理学技术和风洞技术, 测定黏虫的触角对5种植物挥发物的反应, 并进一步评价了植物挥发物与黏虫性诱剂在田间联合应用对成虫的诱捕效果, 为黏虫性诱剂的高效利用和虫情监测提供依据。电生理学试验结果表明, 黏虫雌、雄蛾对苯乙醛、芳樟醇、Z-3-己烯基乙酸酯的反应有显著差异(P<0.05)。除α-法尼烯外, 黏虫雌、雄蛾对植物气味化合物的触角电位值均随浓度的升高而升高; 风洞行为试验结果表明, 与对照相比, 雄蛾对苯乙醛、β-石竹烯、Z-3-己烯基乙酸酯均表现出逆风飞行行为(比例分别为 50.6%、50.3%和44.9%), 芳樟醇则对雄蛾具有一定的驱避作用。田间试验结果表明, 单一植物挥发物对黏虫的吸引力较小, 且各挥发物之间无显著差异; 苯乙醛、β-石竹烯、Z-3-己烯基乙酸酯(1∶1∶1)和性诱剂组合配方的引诱效果最佳, 诱捕量是单独使用性诱剂的1.8倍(P <0.05)。
英文摘要:
      Mythimna separata (Walker) is a seasonal, long-distance migratory pest which causes significant damage to food crops in the past several years in China. In order to provide an effective method for predicting its migration and population dynamics, we used electrophysiological and wind tunnel techniques to test the response of M.separata to several plant volatiles, and further evaluated the trapping effect of sex attractants combined with plant volatiles in the field. EAG tests showed that the male and female moths had significant differences in their responses to phenylacetaldehyde, linalool, and Z-3-hexenyl acetate (P<0.05). EAG values increased with increasing concentrations of plant volatiles, except for α-farnesene. The wind tunnel behavior test showed that the upwind behavior of male moths for phenylacetaldehyde, β-caryophyllene and Z-3-hexenyl acetate reached 50.6%, 50.3% and 44.9%, respectively, compared to the control, while linalool showed a certain repellent effect against M. separata. Field experiments showed that the single plant volatiles were less attractive to the oriental armyworm and there was no significant difference among all tested volatiles. The combination of phenylacetaldehyde, β-Caryophyllene, Z-3-hexenyl acetate (1∶1∶1) with sex pheromones of M. separata had the best attractive effect in all formulas and the ratio of insect attraction to pheromone alone reached 1.8 (P<0.05).
