摘　　要：植物挥发物在害虫的寄主选择过程中发挥着重要作用。植物源引诱剂是一类重要的害虫绿色防控产品,也是目前害虫无害化防治的研究热点。但目前大多数研究还未达到田间可应用的程度。其主要原因是田间引诱效率不理想。已有研究显示田间背景气味可干扰昆虫的嗅觉定向,干扰植物源引诱剂的引诱效率。因此对以往忽略的田间背景气味干扰加以重视,可进一步加快植物源引诱剂的研发进程。本文从气味传播与昆虫嗅觉感知、背景气味干扰嗅觉定向、田间背景气味复杂性和其对引诱剂的干扰等方面进行了综述与探讨,并对引诱剂配方组配过程中如何降低田间背景气味的干扰提出了相应的研发策略,以期促进植物源引诱剂的创新发展。Plant volatiles are the key information for host-plant selection by herbivorous pests.The attractants based on plant volatiles can function as an important technique for pest control,and is one of the research focuses in green control techniques.But most related researches have not reached the stage of field application.The main reason is that the attractive efficiency was unsatisfactory in field.Some research has shown that field background odor could disturb the olfactory orientation of insect and impair the pest attractiveness of plant volatile-based attractants.Therefore,close attention to the previously-ignored interference of field background odor could speed up the development process of plant volatile-based attractants.In this paper,odor transportation,insect olfactory perception,the interference of background odor with insect olfactory orientation,and the complexity of field background odor and its interference with attractants were summarized and discussed,and coping strategies were suggested to reduce the interference of field background odor in the process of attractant development.The review is expected to promote the innovative development of attractants for crop insect pests.
