Liriomyza sativae Blanchard and Liriomyza huidobrensis (Blanchard) (Diptera: Agromyzidae) are two invasive flies in China that have caused economical damage on vegetables and ornamental plants. In this article, we report the profiles of emitted volatiles from healthy, mechanically damaged, and leafminer-damaged bean, Phaseolus vulgaris L., plants. Among 25 emitted volatiles identified, (E)-2-hexen-1-al, (3E)-4,8-dimethyl-1,3,7-nonatriene (DMNT), (Z)-3-hexenyl acetate, (Z)-3-hexen-1-ol, (syn)- and (anti)-2-methylpropanal oxime, (syn)-2-methylbutanal oxime, linalool, and (E,E)-alpha-farnesene were consistently released from damaged bean plants. Combined amounts of these nine compounds made up more than 70% of the total volatiles emitted from each treatment. No qualitative differences in volatile emission were found between bean plants damaged by the two fly species; however, amounts of several major compounds induced by L. huidobrensis damage were significantly higher than those from plants damaged by L. sativae. The mechanically damaged plants released a higher proportion of green leaf volatiles than plants in the other treatments, whereas leafminer-damaged plants produced more terpenoids and oximes. Furthermore, the volatile profiles emitted from plants, damaged by adult leafminers, by second instar larvae, and even the plants with empty mines left by leafminer larvae (the pupal stage) were significantly different. The identification of volatile oximes released from damaged plants was confirmed and is discussed in a behavioral and biological control context.
美洲斑潜蝇和南美斑潜蝇（双翅目：潜蝇科）是在中国造成经济损失的两种入侵性蝇类，对蔬菜和观赏植物均有危害。在本文中，我们报告了健康、机械损伤和潜叶蝇损伤的菜豆植株释放的挥发性物质概况。在鉴定出的25种释放的挥发性物质中，（E）-2-己烯醛、（3E）-4,8-二甲基-1,3,7-壬三烯（DMNT）、（Z）-3-己烯基乙酸酯、（Z）-3-己烯-1-醇、（顺式）和（反式）-2-甲基丙醛肟、（顺式）-2-甲基丁醛肟、芳樟醇和（E,E）-α-法尼烯在受损菜豆植株中持续释放。这9种化合物的总量占各处理释放的总挥发性物质的70%以上。两种潜叶蝇危害的菜豆植株在挥发性物质释放上没有质的差异；然而，南美斑潜蝇危害诱导产生的几种主要化合物的量显著高于美洲斑潜蝇危害的植株。与其他处理的植株相比，机械损伤的植株释放的绿叶挥发性物质比例更高，而潜叶蝇危害的植株产生更多的萜类化合物和肟类化合物。此外，成虫潜叶蝇、二龄幼虫危害的植株以及甚至潜叶蝇幼虫留下空潜道的植株（蛹期）释放的挥发性物质概况也存在显著差异。对受损植株释放的挥发性肟类化合物的鉴定得到了证实，并在行为和生物防治背景下进行了讨论。
