桉蝙蛾5龄幼虫对白背桐树干挥发物的嗅觉和行为反应
Olfactory and behavioral responses of the fifth-instar larvae of Endoclita vietnamensis to volatiles from the trunk of Mallotus paniculatus
摘要
Abstract
To elucidate the olfactory recognition mechanism of Endoclita vietnamensis fifth-instar larvae to volatiles from Mallotus paniculatus trunks,volatiles components of both healthy and damaged trunk of M.paniculatus were analyzed using dynamic headspace adsorption combined with gas chromatography-mass spectrometry(GC-MS).Key volatile compounds such as terpenes and aromatic hydrocarbons were screened via electroantennogram(EAG),and larval choice behavioral responses to volatiles from the trunk of M.paniculatus were validated using a Y-tube olfactometer.The results showed that volatiles from damaged M.paniculatus trunks significantly attracted the fifth-instar larvae of E.vietnamensis,with compounds such as methylpentanol alcohol eliciting strong antennal responses.Results revealed the complex relationship between M.paniculatus volatiles and larval behavior,providing a theoretical basis for developing pest control strategies based on olfactory interference.关键词
