To clarify the effect of soybean-maize strip intercropping on the occurrence of bean bug Rip-tortus pedestris,a comparative trapping efficiency analysis was conducted in Shandong Province in 2023. Windmill traps were used to investigate the occurrence of R. pedestris across various planting sys-tems in six cities spanning Shandong,Henan,and Anhui provinces. The results indicated that windmill traps were most effective in capturing R. pedestris. Peak infestation of R. pedestris in soybean fields oc-curred from mid-July to mid-August,corresponding to soybean flowering to pod-setting stages. More-over,there was no significant difference in occurrence patterns between soybean-maize strip intercrop-ping and soybean fields. Timing of insecticide application should be synchronized with the number of pests and peak infestation periods.
