Abstract: 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.

Key words: plant volatiles, attractant, olfactory location, background odor, interference
