Abstract The whitefly, Bemisia tabaci Gennadius, is a major phloem-feeding pest of agricultural crops that is also an important vector of many plant diseases. The B. tabaci Mediterranean (‘MED') biotype is a particularly effective vector of Tomato yellow leaf curl virus (TYLCV), a devastating plant pathogen. Although insecticides play an important role in the control of MED and TYLCV, little is known about how TYLCV infection affects MED susceptibility to insecticides. We conducted research addressing how MED susceptibility to flupyradifurone, the first commercially available systemic control agent derived from the butenolide class of insecticides, was affected by TYLCV infection. We first conducted bioassays determining the LC15 and LC50 for control and viruliferous MED feeding on either water- or insecticide-treated plants. We next measured several demographic parameters of control and viruliferous MED exposed to either insecticide- or water-treated plants. TYLCV infection increased MED tolerance of flupyradifurone: the LC15 and LC50 of viruliferous MED were double that of uninfected MED. Viral infection also altered MED demographic responses to flupyradifurone, but in an inconsistent manner. Although the ability of TYLCV and other persistently transmitted viruses to benefit Bemisia via manipulation of host plant defense is well known, this appears to be the first example of virally mediated changes in vector susceptibility to an insecticide.

番茄黄叶卷曲病毒感染改变烟粉虱 MED(半翅目:粉虱科)对氟啶酮的脆弱性

摘要 粉虱 Bemisia tabaci Gennadius 是农作物的主要韧皮部害虫,也是许多植物病害的重要媒介。烟粉虱地中海 ('MED') 生物型是一种特别有效的番茄黄叶卷曲病毒 (TYLCV) 载体,这种病毒是一种毁灭性的植物病原体。尽管杀虫剂在控制 MED 和 TYLCV 方面发挥着重要作用,但关于 TYLCV 感染如何影响 MED 对杀虫剂的敏感性知之甚少。我们进行了研究,以解决 MED 对氟吡呋酮的敏感性如何受到 TYLCV 感染的影响,氟吡呋酮是第一种市售的衍生自丁烯内酯类杀虫剂的全身控制剂。我们首先进行了生物测定,确定了 LC15 和 LC50,用于以水处理或杀虫剂处理的植物为食的对照和带病毒的 MED。我们接下来测量了暴露于杀虫剂或水处理植物的对照和含病毒 MED 的几个人口统计学参数。TYLCV 感染增加了氟吡呋酮的 MED 耐受性:病毒性 MED 的 LC15 和 LC50 是未感染 MED 的两倍。病毒感染也改变了 MED 人口对氟吡呋酮的反应,但方式不一致。虽然 TYLCV 和其他持续传播的病毒通过操纵宿主植物防御使 Bemisia 受益的能力是众所周知的,但这似乎是病毒介导的载体对杀虫剂敏感性变化的第一个例子。有病毒的 MED 的 LC15 和 LC50 是未感染 MED 的两倍。病毒感染也改变了 MED 人口对氟吡呋酮的反应,但方式不一致。虽然 TYLCV 和其他持续传播的病毒通过操纵宿主植物防御使 Bemisia 受益的能力是众所周知的,但这似乎是病毒介导的载体对杀虫剂敏感性变化的第一个例子。有病毒的 MED 的 LC15 和 LC50 是未感染 MED 的两倍。病毒感染也改变了 MED 人口对氟吡呋酮的反应,但方式不一致。虽然 TYLCV 和其他持续传播的病毒通过操纵宿主植物防御使 Bemisia 受益的能力是众所周知的,但这似乎是病毒介导的载体对杀虫剂敏感性变化的第一个例子。
