Abstract  [Objectives]  To compare the effectiveness of pan traps and window traps for investigating the pollinator community of oil-seed rape farmland ecosystems, and thereby provide information to inform the monitoring, utilization, and protection, of insect-pollinators. [Methods]  From February to April 2021 (the rape flowering period), the relative effectiveness of pan and window traps with respect to characterizing the pollinator community was measured in 30 rape seed plots in the Science and Technology Ecological Park of Jiangxi Agricultural University. [Results] Significantly more insect-pollinators were captured by window traps (297.43 ± 20.06) than by pan traps (85.63 ± 5.15). The total number of species captured by window traps (87) was also higher than that caught by pan traps (82). With respect to community structure, the dominant species captured by window traps and pan traps were similar, however, the insects caught in window traps had higher species similarity and homogeneity than those caught in pan traps. With respect to the dominant insect-pollinators, a significantly higher number and richness of the Lepidoptera, Hymenoptera and Diptera were caught in window traps than in pan traps. [Conclusion] Window traps are significantly better than pan traps for revealing the diversity and richness of insect-pollinators in oil-seed rape fields and should therefore replace pan traps in agricultural ecosystems.
