Phototactic behavior 6: behavioral responses of Myzus persicae (Hemiptera: Aphididae) to light-emitting diodes

Abstract

The behavioral responses of Myzus persicae adults to light-emitting diodes (LEDs) were evaluated under optimal conditions (luminance intensities, light exposure times, and specific wavelengths). Based on the attraction rate (%) of M. persicae adults under optimal conditions, the green LED (520 ± 5 nm) showed the highest potential attraction rate (85.3 %), followed by the blue (470 ± 10 nm, 75.0 %), yellow (590 ± 5 nm, 73.7 %), and red LED (625 ± 10 nm, 69.7 %). The green LED (520 ± 5 nm) was approximately 1.4 times (61.7 %) more attractive than that of a black light bulb, which served as the positive control. In conclusion, the green LED (520 ± 5 nm) was suitable for attracting M. persicae adults under optimal conditions (40 lx and 120 min).
