Abstract
To evaluate high-power light-emitting diodes (HPLEDs) as potential attractants for Spodoptera Exigua adults, attractiveness of specific wavelengths, illuminance intensity, and light-exposure times were investigated and compared to that of fluorescent light. The white light (40 lux treatment) attracted significantly more S. exigua than other attractants. The optimal lightexposure time, based on the highest attraction rate, was 60 min. Evaluation of attraction and repellent rates under optimal conditions showed the white HPLED had the highest attraction rate (91.1%), and the red HPLED had the highest repellence rate (33.3%). Based on relative efficiency values, the white HPLED was about 9.14 times as efficient as the fluorescent light. These data clearly showed that S. exigua showed the greatest attraction to the white HPLED at 40 lux intensity and 60 min light-exposure time.
