In this paper, the volatiles from cowpea and kidney bean, the main host plants of American leafminer Liriomyza sativae, were collected and extracted by a self-designed device and solid phase microextraction (SPME) technique, and analyzed by GC-MS. The results showed that the volatiles from the two beans had the same components mainly consisted of 2-hexenal, 3-Hexen-1-ol, 2-Hexen-1-ol, 1-Octen-3-ol, 3-Hexenol acetate, alpha-Ionone and beta-Ionone. The lure made of the seven components was attractive to L. sativae in field trapping trials. Detailed analyses indicated that alpha-Ionone and beta-Ionone might play important roles in the searching behavior of L. sativae for host plants.
本文采用自行设计的装置和固相微萃取（SPME）技术，采集并提取了美洲斑潜蝇主要寄主植物豇豆和菜豆的挥发物，并用气相色谱-质谱联用仪（GC-MS）进行分析。结果表明，两种豆类的挥发物成分相同，主要包括2-己烯醛、3-己烯-1-醇、2-己烯-1-醇、1-辛烯-3-醇、3-己烯醇乙酸酯、α-紫罗兰酮和β-紫罗兰酮。在田间诱捕试验中，由这七种成分制成的诱捕剂对美洲斑潜蝇具有吸引力。详细分析表明，α-紫罗兰酮和β-紫罗兰酮可能在美洲斑潜蝇寻找寄主植物的行为中起重要作用。
