在过去的10年里，我们的温室番茄遭受了含病毒烟粉虱（Gennadius）（半翅目：粉虱科）的攻击。根本的对策是在温室窗户上安装电场屏蔽，以防止它们进入。然而，虽然保护是有效的，但它是不完整的，因为在温室入口区域缺乏警卫;事实上，当工人进出时，害虫从入口门进入。为了解决这个问题，我们开发了一种便携式静电昆虫清扫器作为屏幕的补充技术。在该清扫器中，八根绝缘导线（ICW）沿聚氯乙烯（PVC）管以恒定间隔沿着排列，并覆盖有圆柱形不锈钢网。ICW和金属网连接到握把内的直流电压发生器（由3V碱性电池操作），并反向通电以在它们之间产生电场。植物上的粉虱被吸引到沿着叶子轻轻沿着的清扫器上。该装置易于在温室中现场操作，并且能够捕获在番茄植物的常规护理期间检测到的粉虱。使用这种装置，我们抓住了所有侵入无防护入口门的粉虱，并最大限度地减少了温室番茄植物中病毒性疾病的出现和传播。
Our greenhouse tomatoes have suffered from attacks by viruliferous whiteflies Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) over the last 10 years. The fundamental countermeasure was the application of an electric field screen to the greenhouse windows to prevent their entry. However, while the protection was effective, it was incomplete, because of the lack of a guard at the greenhouse entrance area; in fact, the pests entered from the entrance door when workers entered and exited. To address this, we developed a portable electrostatic insect sweeper as a supplementary technique to the screen. In this sweeper, eight insulated conductor wires (ICWs) were arranged at constant intervals along a polyvinylchloride (PVC) pipe and covered with a cylindrical stainless net. The ICWs and metal net were linked to a DC voltage generator (operated by 3-V alkaline batteries) inside the grip and oppositely electrified to generate an electric field between them. Whiteflies on the plants were attracted to the sweeper that was gently slid along the leaves. This apparatus was easy to operate on-site in a greenhouse and enabled capture of the whiteflies detected during the routine care of the tomato plants. Using this apparatus, we caught all whiteflies that invaded the non-guarded entrance door and minimized the appearance and spread of the viral disease in tomato plants in the greenhouse.
