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.
