The application of green manure is crucial for achieving sustainable agriculture and animal husbandry, but pest management is often overlooked. Conducting a risk assessment for insect pests in green manure is essential. The beet webworm, , a polyphagous insect, is currently experiencing an outbreak in northern China, and represents a significant migratory pest. A two-sex life table and flight mill test approach was used to comprehensively evaluate the effects of three major legume green manure crops (, , and ) on the growth, development, fecundity, and flight ability of in China. Our findings indicate that cannot utilize for generational development. shows reduced performance on and compared to its suitable host . However, both the population parameters (, , , and ) and the population prediction results suggest that can adapt to and . In the process of promoting green manure, careful consideration should be given to the selection of appropriate green manure varieties and the implementation of effective pest control measures during their planting. Our findings lay the groundwork for the promotion of green manure and implementation of an ecological management plan for .
绿肥的应用对于实现可持续农牧业至关重要，但害虫管理往往被忽视。对绿肥中的害虫进行风险评估至关重要。甜菜夜蛾是一种多食性昆虫，目前在中国北方爆发，是一种重要的迁飞性害虫。采用两性生命表和飞行磨测试方法，全面评估了三种主要豆科绿肥作物（紫云英、苕子和箭筈豌豆）对中国甜菜夜蛾生长、发育、繁殖力和飞行能力的影响。我们的研究结果表明，甜菜夜蛾不能利用紫云英进行世代发育。与适宜寄主大豆相比，甜菜夜蛾在苕子和箭筈豌豆上的表现有所下降。然而，种群参数（净增殖率、内禀增长率、周限增长率和平均世代周期）和种群预测结果均表明，甜菜夜蛾能够适应苕子和箭筈豌豆。在推广绿肥的过程中，应谨慎考虑选择合适的绿肥品种，并在其种植过程中实施有效的害虫防治措施。我们的研究结果为绿肥的推广及甜菜夜蛾生态管理计划的实施奠定了基础。
