Abstract: 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,α-Ionone and β-Ionone.The lure made of the seven components was attractive to L.sativae in field trapping trials.Detailed analyses indicated that α-Ionone and β-Ionone might play important roles in the searching behavior of L.sativae for host plants.
