摘要： Seed predation by insect herbivores reduces crop productionworldwide.Foraging on seeds at pre-dispersal generally means that females needto find the suitable host plant within a relatively short timeframein order to synchronize larval development with seed production. Themechanistic understanding of host finding by seed pests can be harnessedfor more sustainable pest management strategies. We here studied thechemical communication between the bean bug Riptortuspedestris, a major pest of legumes, and several cropspecies and cultivars in the Fabaceae. Via a comparative chemicalanalysis, we found that 1-octen-3-ol is the principal constituentof the floral scents of most species tested in the subfamily Faboideae,including soybean and faba bean. With field trapping and laboratorybioassays, including electroantennography, we further revealed thatthis compound can be perceived, and stimulate attraction responses,by R. pedestris nymphs and adults.The addition of 1-octen-3-ol to pheromone traps might therefore improvetrapping efficacy for controlling populations of this important granivorepest on legumes.
