摘要： Riptortus pedestris (Hemiptera: Alydidae) is a notable soybean pest, with diapause and non-diapause individuals showing different sensitivities to aggregation pheromones. This study aimed to investigate how R. pedestris detects aggregation pheromones through electroantennogram (EAG) and behavioral experiments, transcriptome sequencing and qRT-PCR, as well as competitive fluorescence-binding assay. Results indicated that diapausing females and males of R. pedestris exhibited a heightened EAG response and were more attracted to the aggregation pheromone components compared to their non-diapause counterparts. Transcriptome sequencing and qRT-PCR analyses revealed significantly higher expression of RpedOBP1 in the antennae of diapause females and males compared to non-diapausing R. pedestris. The competitive fluorescence-binding assay demonstrated that RpedOBP1 displayed the strongest binding affinity to E2HE2H, suggesting its crucial role in recognizing the aggregation pheromone. These findings have the potential to inform the development of integrated pest management strategies utilizing behavioral approaches for bean bug control.
