The experiment on the trapping effect of food attractant on rice leaf folder was carried out in Songjiang of Shanghai from June to October in 2021, in comparison with traditional methods such as sex pheromone trapping, light trapping. Food attractant trapping was overall better than sex pheromone trapping. The proportion of female adults in grade I ovary was 30.95%, and the non-mating rate was 96.15%. The number of trapped females was significantly higher than that of males, with a female-to-male ratio of 2.34. Thus, food attractant trappings can trap both male and female and trap unmatched females at low-level ovarian development stage, which provides a theoretical basis for the green control of rice leaf folder.
