Abstract
The attraction of melon thrips, Thrips palmi Karny(Thysanoptera: Thripidae), to reflective-type traps combined with blue sticky board and a blue light emitting diode(LED)array was investigated in July 2011 in an eggplant greenhouse. The peak wavelength of the blue LED array was 470 nm. The LED array was placed close to the plants and directed toward the sticky board. The number of adult thrips caught by the reflective-type trap at a light intensity of 3×1017 photons/(m2·s)was significantly greater than the number caught by the control, a non-illuminated trap. Furthermore, the number of adult thrips caught by the reflective-type trap was significantly greater than that for the control during 18:00–21:00 and 21:00–0:00. Additionally, significantly more female adult thrips were caught by the reflective-type trap than by the non-illuminated trap, especially during the 18:00–21:00 time period.
