生物防治是未来害虫防治的重要方向，化学生态学是生物防治不可缺少的组成部分。为此，本研究进行了斜纹夜蛾及其寄生蜂对不同处理甘蓝挥发物的选择性试验，并对不同处理甘蓝挥发物进行了收集和分析。本研究发现，甘蓝被斜纹夜蛾取食后，产生挥发物以避开斜纹夜蛾，同时也吸引相似侧沟茧蜂。结果表明，部分化合物与斜纹夜蛾和拟侧沟茧蜂的行为有关。研究结果为寻找生物防治资源和化学防治提供了理论依据。摘要植物对食草性昆虫攻击的反应是释放挥发物，直接伤害食草性昆虫或通过吸引天敌间接伤害食草性昆虫。虽然斜纹夜蛾（Spodoptera litura）幼虫能诱导寄主植物挥发性物质的释放，但这些挥发性物质对斜纹夜蛾（Spodoptera litura）寄主定位的影响尚不清楚。斜纹夜蛾的天敌拟侧沟茧蜂Microplitis similis。斜纹夜蛾幼虫，人们知之甚少。在这里，我们发现S. litura幼虫和S.斜纹夜蛾侵染的甘蓝叶片对M.相似的S.斜纹夜蛾对感染过S. 24或48 h。M.植物的选择性与柠檬烯、芳樟醇和十六烷的释放量呈正相关，与（E）-2-己烯醛、1-丁烯、4-异硫氰酸酯的释放量呈负相关。S.斜纹夜蛾对植物的选择与（E）-2-己烯醛、1-丁烯、4-异硫氰酸酯和癸醛的释放呈正相关，与柠檬烯、壬醛、十六烷、十七烷和十八烷的释放呈负相关。结果表明，寄主植物挥发性物质可以调控该虫的行为。litura和M.相似的
Simple Summary Biological control is an important direction for pest control in the future, and chemical ecology is an indispensable part of biological control. Therefore, we tested the selection of Spodoptera litura and parasitic wasps on the volatiles of different treatments of cabbage and collected and analyzed the volatiles of different treatments of cabbage. This study found that cabbage was fed by Spodoptera litura to produce volatiles to avoid Spodoptera litura while also attracting Microplitis similis. As a result, some compounds were found to be related to the behavior of Spodoptera litura and Microplitis similis. These results provide a theoretical basis for searching for biological control resources and chemical control. Abstract Plants respond to herbivorous insect attacks by releasing volatiles that directly harm the herbivore or that indirectly harm the herbivore by attracting its natural enemies. Although the larvae of Spodoptera litura (the tobacco cutworm) are known to induce the release of host plant volatiles, the effects of such volatiles on host location by S. litura and by the parasitoid Microplitis similis, a natural enemy of S. litura larvae, are poorly understood. Here, we found that both the regurgitate of S. litura larvae and S. litura-infested cabbage leaves attracted M. similis. S. litura had a reduced preference for cabbage plants that had been infested with S. litura for 24 or 48 h. M. similis selection of plants was positively correlated with the release of limonene; linalool and hexadecane, and was negatively correlated with the release of (E)-2-hexenal and 1-Butene, 4-isothiocyanato. S. litura selection of plants was positively correlated with the release of (E)-2-hexenal, 1-Butene, 4-isothiocyanato, and decanal, and was negatively correlated with the release of limonene, nonanal, hexadecane, heptadecane, and octadecane. Our results indicate that host plant volatiles can regulate the behavior of S. litura and M. similis.
