美国白蛾对几种蔬菜危害风险性评估试验

摘要

[Objective]To cope with the possible sudden epidemic situation on vegetables by Hlyphantria cunea(Drury) in the future, the risk of damage of Hlyphantria cunea(Drury)to different vegetables was assessed.[Method]Compared with catalpa, larvae of Hlyphantria cunea(Drury)was fed with the leaves of tomato, eggplant, bean, celery, radish, cucumber and Chinese cabbage. Growth status, mortality and pupation of the larvae in all these vegetables were observed to access its risk of damage.[Results] Hlyphantria cunea(Drury) larvae couldn't survive in eggplant, tomato and bean leaves. In all of the vegetables, Hlyphantria cunea(Drury)'s pupation was observed on cabbage and cucumber leaves.[Conclusion] Hlyphantria cunea(Drury) had the most potential risk of damage on cucumber and Chinese cabbage in common vegetables.%[目的] 评估美国白蛾对不同蔬菜危害的风险性,以期应对未来可能突发的美国白蛾疫情对蔬菜的危害.[方法]通过人工利用番茄、茄子、菜豆、芹菜、萝卜、黄瓜、白菜叶片饲养美国白蛾幼虫,以梓树为对照,观察各种蔬菜上的美国白蛾幼虫生长情况、死亡数和化蛹数,进行危害风险性评估.[结果]美国白蛾幼虫不能在茄子、番茄、菜豆叶片上存活;在各蔬菜处理中,美国白蛾幼虫可在白菜和黄瓜叶片上正常化蛹.[结论]美国白蛾对常见蔬菜黄瓜和白菜的潜在危害风险性最大
