文献主题：Simple Summary

The western flower thrips Frankliniella occidentalis (Thysanoptera: Thripidae) is a major pest of vegetable and flower crops worldwide. A feasible and environmentally friendly method to control F. occidentalis is to induce resistance in host plants. In this study, we attempted to induce resistance against F. occidentalis in faba bean plants. We first investigated the effect of different concentrations of jasmonic acid (JA) and ethylene (ET) alone on the oviposition of F. occidentalis. We then used different concentrations of the combined treatment (JA and ET) to evaluate the most suitable concentrations affecting the oviposition and feeding selectivity of F. occidentalis. Second, we examined the effects of mixed exogenous JA and ET treatments on the activities of JA and ET biosynthetic enzymes in faba bean leaves and on the expression levels of JA/ET pathway marker genes. Finally, we evaluated the effects of JA/ET treatment-related induced resistance on the life history and population parameters of F. occidentalis. Our results provide reference data for the control of thrips infestation in faba bean crops via application of exogenous phytohormones.
