椰子芯叶2种挥发物对红棕象甲成虫行为影响
Effects of two volatiles compounds from coconut palm core leaves on the behavioral of Rhynchophorus ferrugineus adults
摘要
Abstract
[Objective]The objective of this study was to elucidate the behavioral responses of Rhynchophorus ferrugineus to the volatile compounds E,E-2,4-nonadienal and trans-2-nonenal from coconut core leaves.[Methods]Using indoor bioassay meth-ods,we investigated the selection behavior of R.ferrugineus individuals reared in the laboratory and wild individuals from the field in response to two volatiles from coconut core leaves,and analyzed the effects of coconut volatiles on probing and oviposi-tion by female red palm weevils.[Results](1)After treatment with E,E-2,4-nonadienal,laboratory-reared males showed a sig-nificant positive preference;After treatment with trans-2-nonenal,both females and males exhibited significant positive prefer-ence towards the volatile-treated group.(2)After treatment with E,E-2,4-nonadienal,laboratory-reared females showed signif-icantly higher probing numbers on the treated coconut peels compared to the control group.(3)After treatment with E,E-2,4-nonadienal,there were no significant differences in the single-female oviposition amount and successful oviposition rate among all tested insects compared to the control.In contrast,after treatment with trans-2-nonenal,laboratory-reared females showed significantly higher preference for oviposition on coconut peels than the control group,and the probing oviposition success rate reached a highly significant level compared to the control.(4)In the competitive selection results for trans-2-nonenal and E,E-2,4-nonadienal treatments,laboratory-reared and field-trapped red palm weevils did not show significant differences in behavior-al selection,probing,and oviposition.[Conclusion]There were differences in the directional preference of different R.ferrugin-eus populations towards volatile compounds E,E-2,4-nonadienal and trans-2-nonenal from coconut palm core leaves,which al-so affected the later probing and oviposition success rates.Meanwhile,there was no difference in the competitive selection of red palm weevils for these two volatile compounds.关键词
