Abstract

Tobacco thrips (Frankliniella fusca Hinds) feeding can reduce peanut (Arachis hypogaea L.) yield and vector Tomato spotted wilt orthotospovirus (family Tospoviridae, genus Orthotospovirus). Visible injury caused by tobacco thrips feeding was recorded from 2013 to 2022 at one location in North Carolina when peanut was not treated with insecticide, when imidacloprid or phorate was applied in the seed furrow at planting, and when acephate was applied to peanut approximately 21 days after peanut emergence. A positive linear response for peanut injury caused by tobacco thrips was observed from 2013 through 2022 for non-treated peanut and peanut treated with imidacloprid and phorate. No difference in injury caused by tobacco thrips was noted for acephate. In a survey of farmers in 2022 cropping cycle, the most popular systemic insecticide applied at planting for this pest in North Carolina and Virginia was imidacloprid. The majority of farmers in these states indicated that control of tobacco thrips was more difficult now than in previous years, and that they made routine applications of acephate to control this pest.

杀虫剂对烟草蓟马的防治及花生种植户防治措施的调查

烟草蓟马（Frankliniella fusca Hinds）的摄食会降低花生（Arachis hypogaea L.）的产量，其传播媒介为番茄斑点枯萎病正形孢子病毒（Tospoviridae, genus orthotospovirus）。2013年至2022年，在北卡罗来纳州的一个地点，记录了烟草蓟马在不施用杀虫剂、播种时在种沟施用吡虫啉或磷酸酯以及在花生出苗后约21天施用甲胺磷时摄食花生造成的可见伤害。2013 ~ 2022年，未处理花生和吡虫啉加磷酸处理花生对烟草蓟马危害呈线性正响应。甲胺磷对烟蓟马的伤害无显著影响。在对2022年种植周期的农民进行的一项调查中，北卡罗来纳州和弗吉尼亚州种植这种害虫时最常用的系统杀虫剂是吡虫啉。这些州的大多数农民表示，现在控制烟草蓟马比前几年更加困难，他们经常使用乙酰甲胺磷来控制这种害虫。
