The purpose of this study was to determine the wavelengths of reflected light that attract and repel the greenhouse whitefly, Trialeurodes vaporariorum (Westwood). The authors made 12 kinds of colored sticky board traps using Tyvek® sheets to reflect light and sharp-cut filters as optical filters and tested them in a greenhouse in which tomatoes were cultivated. By analyzing the number of whitefly catches on each sticky trap, we determined that the most attractive wavelengths were from 464 to 587 nm, and that wavelengths less than 464 nm repelled the insects.
