中文摘要：棉田烟粉虱是许多作物上最重要的害虫之一，是100多种植物病毒的介体，可导致全球范围内作物重大损失。控制烟粉虱和抑制主要病毒如番茄黄化曲叶病毒（TYLCV）一样，对稳定产量具有极大的重要性。本文研究了一种新的系统性丁烯酸内酯杀虫剂氟吡呋喃酮对抗烟粉虱和病毒传播的功效。研究结果表明，氟吡呋喃酮是作物综合管理中一个非常有用的、快速的化学工具，可同时控制烟粉虱、抑制病毒侵染。
外文摘要：BACKGROUND：The cotton whitefly Bemisia tabaci (Gennadius) is among the most important pests of numerous crops and a vector of more than 100 plant viruses, causing significant crop losses worldwide. Managing this pest as well as inhibiting the transmission of major viruses such as tomato yellow leaf curl virus (TYLCV) are of utmost importance for sustainable yields. The efficacy against both whitefly and virus transmission of the novel systemic butenolide insecticide flupyradifurone was investigated in this study.
RESULTS：The inhibition of TYLCV transmission by flupyradifurone was compared to that by thiamethoxam, a neonicotinoid insecticide reported to inhibit virus transmission. The experiment was performed under high virus pressure conditions (10 viruliferous insects per plant for 48 h) using a fully characterized field strain of B. tabaci. The insecticides were foliarly applied at recommended label rates under greenhouse conditions. Flupyradifurone suppressed virus transmission by 85% while levels of suppression after thiamethoxam treatments were just 25% and significantly lower. In untreated control plots, 100% of plants were infected by TYLCV. The observed difference in the potential to suppress virus transmission is linked to a strong knockdown effect as well as prolonged feeding inhibition in flupyradifurone treatments. CONCLUSION：Flupyradifurone is shown to be an extremely useful, fast-acting, new chemical tool in integrated crop management offering simultaneous control of whiteflies and strong suppression of viral infections via its rapid knockdown action and good residual activity.
