Attraction Effects of LED Trap to Spodoptera exigua Adults in the Greenhouse

Abstract

The attraction effects of light emitting diode (LED) trap to Spodoptera exigua adults were evaluated in greenhouse and compared with those of no light trap and black-light trap, which is typical used in commercial trap. 7 days later, white LED trap (83.0±0.7) was 2.4 times more attractive than black-light trap (34.0±2.6), whereas the no light trap was little attractive to S. exigua. These results suggest that white LED traps could be used for environmental insect control.
