[Analysis and identification of Liriomyza sativae-attractants from cowpea and kidney bean volatiles].
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.
