Oviposition preferences of Anoplophora glabripennis on three host plants and composition analysis of host plant volatiles
摘要
Abstract
Anoplophora glabripennis (Motschulsky) have a wide range of host plants and endanger both of the health host and the stressed host. In order to find the plant volatiles which affect oviposition behaviors and lay the foundation for the development of green attractant of A. glabripennis. The oviposition preference of three host plants, Salix ohsidare, Melia azedarach and Acer negundo, was tested by laboratory the selective and no-selective oviposition test. The volatile components of three host plants were analyzed by the method of dynamic headspace adsorption to combine Gas Chromatography-Mass Spectrometry (GC/MS). The results of both the se-lective and the no-selective test showed that S. ohsidare was the most suitable for ovipositing by A. glabripen-nis, followed by M. azedarach, and finally A. negundo. The success rate of oviposition of A. glabripennis on S. ohsidare was 69.4%, and the one on A. negundo was 0. The results of host volatiles analysis showed that 16 compounds were found in S. ohsidare, and 11 compounds were detected in M. azedarach and A. negundo. 3-Carene and 2-ethyl-Hexanal only tested in S. ohsidare. The contents of nonanal, styrene, and acetophenone in S. ohsidare were significantly higher than M. azedarach and A. negundo. In the above five compounds, 3-carene and nonanal were reported to show the attraction on A. glabripennis, so we speculate that 3-carene and nonanal may be the effective components for attracting oviposition of A. glabripennis females.关键词
