Control of greenhouse whitefly, Trialeurodes vaporariorum using visually attractive targets impregnated with pyriproxyfen

The chemosterilant effect of a photo-stable juvenoid, pyriproxyfen, was investigated on greenhouse whitefly. Yellow fabric lures coated with 1 mg of pyriproxyfen per cm2 drastically suppressed whitefly populations on bean plants in laboratory and glasshouse experiments. Numbers of eggs and larvae were reduced practically to zero over a period of several weeks. The success of such treated rectangular targets (25 cm×5 cm) placed among bean plants in a glasshouse prompted the development of Lano®-Tape, a roll of yellow tape treated with pyriproxyfen. It provides a labor saving method of whitefly control in commercial glasshouses as a substitute for conventional insecticide application techniques. © Pesticide Science Society of Japan
