Responses by adults of Plutella xylostella to various colored sticky vinyl chloride plates showed that more adults were caught on yellow than the other colors tested, including clear, blue and red. Based on percent reflectance, the attractive range was in the 400-600 nm region but the moth preferred around the 550 nm region. The higher intensity of reflectance in the 550 nm region might be responsible for the greater attraction to saturated yellow compared with clear and blue plates. For tinted yellows, both reflection in the 550 nm region and in the ultraviolet region might be important. A greater number of males than females were caught on the traps, irrespective of color. The significant correlation (r=0.83) obtained between the estimated number of adults caught per day and the mean number of emerged moths per day, suggested that the trap could be used for forecasting adult population density in the field.
