Abstract：Cnaphalocrocis medinalis(Gueneé)is an important migratory pest on rice in Shandong Prov-ince.Green control technologies play crucial roles in comprehensive management of this pest.Bisexual lures,which could simultaneously release plant-derived compounds and insect sex pheromones,function as both food and sexual attractants.To evaluate the effectiveness of attractant products,a study was conducted using attract-ant+trap method to assess the trapping effects of C.medinalis bisexual lures in four rice-growing areas of Shan-dong Province.The findings revealed that the bisexual lures could attract both male and female adults of C.medinalis with no significant difference in the number between them.However,the trapped number of C.medi-nalis varied among areas.The C.medinalis bisexual lures could also attract other rice insects such as Chilo suppressalis and Sesamia inferens.The efficacy of sex pheromone lures in attracting the target pest C.medinalis was either higher or comparable to that of the bisexual lures.In summary,sex pheromone lures exhibited high-er specificity,but bisexual lures could attract not only both male and female individuals,but also other in-sects,so they could be used for green prevention and control of rice pests.
