Abstract:

【Objective】 This study was conducted to identify the volatile components of Acer saccharum, explore how the volatile constituents of Acer saccharum affect the host position of Anoplophora glabripennis, analyze the role of host volatiles in the search for and host positioning of Anoplophora glabripennis, and provide new ideas and a theoretical basis for the comprehensive prevention and control of Anoplophora glabripennis infestations. 【Method】The volatile components of Acer saccharum were identified by TCT-GC-MS. The electrophysiological and behavioral responses of Anoplophora glabripennis to Acer saccharum volatiles were determined by the electroantennogram (EAG) and Y-tube olfactometer. The main volatiles affecting the search and host location of A. glabripennis were identified by multiple comparison methods, an independent sample t test, and a chi-square test analysis. 【Result】The volatiles released from Acer saccharum included 34 volatile compounds, the main components of which were esters (61.67%), alkenes (12.99%), acids (5.58%) and alcohols (5.02%), respectively. There were electrophysiological and behavioral responses to 12 volatile compounds. The electrophysiological and behavioral responses of the female and male A. glabripennis adults were significantly different to the same concentration of different volatiles, the same volatiles, and different concentrations of the same volatiles. Male and female A. glabripennis adults exhibited obvious electrophysiological responses to hexyl acetate, diisobutyl adipate, diisobutyl phthalate, hexenyl acetate, geranyl propionate, cis-3-hexenol, 2-hexyl-1-decanol, ocimene and squalene. Among these, the female and male adults of A. glabripennis showed a significant attraction to hexyl acetate, hexenyl acetater, geranyl propionate, cis-3-hexenol, and 2-hexyl-1-nonanol, while ocimene and squalene had significant repellent effects. Female adults of A. glabripennis were significantly attracted to diisobutyl adipate and lauric acid, but these compounds elicited no behavioral response from male adults. 【Conclusion】 Female and male adults of A. glabripennis are strongly attracted to hexenyl acetater, geranyl propionate, cis-3-hexenol, and 2-hexyl-1-nonanol, while ocimene and squalene show good repellent qualities. Diisobutyl adipate and lauric acid were significantly attractive to female adults of A. glabripennis, but male adults showed no behavioral response.
