Abstract:
The dried bean beetle, Acanthoscelides obtectus, is an economically important pest of stored legumes worldwide. Tracking the human-aided dispersion of its primary hosts, the Phaseolus vulgaris beans, it is now widespread in most bean-growing areas of the tropics and subtropics. In temperate regions where it can only occasionally overwinter in the field, A. obtectus proliferates in granaries, having multiple generations a year. Despite its negative impact on food production, no sensitive detection or monitoring tools exist, and the reduction of local populations still relies primarily on inorganic insecticides as fumigating agents. However, in the quest to produce more nutritious food more sustainably and healthily, the development of environmentally benign crop protection methods is vital against A. obtectus. For this, knowledge of the biology and chemistry of both the host plant and its herbivore will underpin the development of, among others, chemical ecology-based approaches to form an essential part of the toolkit of integrated bruchid management. We review the semiochemistry of the mate- and host-finding behaviour of A. obtectus and provide new information about the effect of seed chemistry on the sensory and behavioural ecology of host acceptance and larval development.
摘要:
干豆甲虫,Acanthelidesobtectus,是世界范围内储存的豆类的重要经济害虫。跟踪其主要宿主的人为分散,菜豆,现在,它在热带和亚热带的大多数豆类种植区都很普遍。在温带地区,它只能偶尔在野外过冬,A.obtectus在粮仓中扩散,一年有多代人。尽管它对粮食生产产生了负面影响,不存在敏感的检测或监测工具,当地人口的减少仍然主要依靠无机杀虫剂作为熏蒸剂。然而,为了更可持续、更健康地生产更有营养的食物,开发环境友好的作物保护方法对A.obtectus至关重要。为此,对寄主植物及其食草动物的生物学和化学的知识将支持以下方面的发展,其中,基于化学生态学的方法,构成布鲁奇综合管理工具包的重要组成部分。我们回顾了A.obtectus的交配和寄主发现行为的化学信息素,并提供了有关种子化学对寄主接受和幼虫发育的感觉和行为生态学的影响的新信息。
