植物在受到植食性昆虫侵害后会释放出多种挥发物和植食性诱导的植物挥发物（HIPVs），这些挥发物在与其他植物和昆虫的相互作用中发挥着多种作用。喜旱莲子草粉蚧Agasicles hygrophila Selman and沃格特（鞘翅目：粉蚧科）是喜旱莲子草Alternanthera philoxeroides（Mart.）葛瑞瑟布在这里，我们报道了A的挥发物之间的差异。通过固相微萃取（SPME），使用气相色谱-质谱仪（GC-MS）对喜旱莲子草属植物进行分析。比较了（1）清洁植物（CK）、（2）A.机械损伤处理（MD）的空心莲子草植物;空心莲子草植株感染A.湿蝇第1、2、3期幼虫及雌、雄成虫。共记录到97种挥发物，其中5种在所有处理中一致出现，而61种仅在A.空心莲子草A.嗜湿植物，如反式橙花叔醇、（E）-β-法呢烯、（3E，7 E）-4，8，12-三甲基十三碳-1，3，7，11-四烯（E，E-TMTT）等。97种挥发性化合物中，烯烃类化合物37种，烷烃类化合物29种，酯类化合物8种，醇类化合物8种，酮类化合物6种。正交偏最小二乘判别分析（OPLS-DA）结果表明，不同处理间挥发性物质的分离度最大，其中19种挥发性物质对不同处理间的分离贡献最大，且VIP值大于1。结果表明，不同时期的A.不同种类的植物所释放的挥发性化合物在数量和质量上都不同。本研究结果为利用挥发性有机物（VOCs）和扬子草的HIPVs提高扬子草的防除效果奠定了重要基础。humyphila在A.空心莲子草
Plants release a variety of volatiles and herbivore-induced plant volatiles (HIPVs) after being damaged by herbivorous insects, which play multiple roles in the interactions with other plants and insects. Agasicles hygrophila Selman and Vogt (Coleoptera: Chrysomelidae) is a monophagous natural enemy and an effective biocontrol agent for Alternanthera philoxeroides (Mart.) Griseb. Here, we reported differences among the volatiles of A. philoxeroides by solid phase microextraction (SPME) using a gas chromatography-mass spectrometer (GC-MS). We compared the volatile emission of: (1) clean plants (CK); (2) A. philoxeroides plants with mechanical damage treatment (MD); and (3) A. philoxeroides plants infested with A. hygrophila 1st, 2nd, and 3rd larvae and female and male adults. A total of 97 volatiles were recorded, of which 5 occurred consistently in all treatments, while 61 volatiles were only observed in A. philoxeroides infested by A. hygrophila, such as trans-nerolidol, (E)-β-farnesene, and (3E,7E)-4,8,12-trimethyltrideca-1,3,7,11-tetraene (E, E-TMTT), etc. Among the 97 volatile compounds, 37 compounds belong to alkenes, 29 compounds belong to alkanes, and there were 8 esters, 8 alcohols and 6 ketones. Orthogonal partial least squares-discrimination analysis (OPLS-DA) showed that the different treatments were separated from each other, especially insect feeding from CK and MD treatments, and 19 volatiles contributed most to the separation among the treatments, with variable importance for the projection (VIP) values > 1. Our findings indicated that the alligatorweed plants could be induced to release volatiles by different stages of A. hygrophila, and the volatile compounds released differ quantitatively and qualitatively. The results from this study laid an important foundation for using volatile organic compounds (VOCs) and HIPVs of alligatorweed to improve the control effect of A. hygrophila on A. philoxeroides.
