金龟子对植物气味趋避机制研究进展

The Mechanism of Plant Odor Reaction of Scarab: Research Advances

金龟子危害园艺作物较为严重,且不易防治。目前以化学防治为主,但是化学防治施药量大,易造成环境污染及农药残留。采用间作诱集、驱避植物的农业措施是防治金龟子的有效途径。本文根据金龟子对植物趋避现象,从植物挥发物气体成分及筛选、金龟子触角结构、嗅觉相关蛋白等方面综述了金龟子对植物挥发性气味趋避机制研究进展。表明利用植物气味对金龟子的诱集或驱避作用,在田间合理间作不同作物,均对金龟子有防治作用;评价筛选对金龟子有作用的挥发性气味目前应用最为广泛的手段是触角电位分析及相关技术;金龟子各种嗅觉蛋白研究主要集中在气味结合蛋白与化学感受蛋白的功能与定位上。通过本综述了解了金龟子与植物互作的研究重点,为今后的研究提供了理论方向。

Scarabs are harmful to horticultural crops and not easy to control.At present,chemical control is the mainstay,but the large application amount of chemical pesticides could cause environmental pollution and pesticide residue.The use of agricultural measures as intercropping trap or repel plant is an effective way to control chafers.Based on the plant avoidance phenomenon of chafer,we reviewed the research progress of the motility mechanism of the chafer on plant odor from the aspects of plant volatiles gas composition and screening,antennae structure of the chafer,olfactory related protein and so on.It indicated that the plant could be used for trapping or repellent of the chafer,and intercropping of different crops in field could prevent and control the chafer;the most widely used method for evaluating and screening the volatile odor which had a role in the chafer was electroantennography and related techniques;the research on various olfactory proteins of chafers mainly focused on the function and localization of odor-binding proteins and chemosensory proteins.Through this review,we summarize the research focus of chafer and plant interaction,and provide a direction for future research.
