Abstract

This study evaluated the attraction responses of adult gypsy moths (Lymantria dispar Linnaeus) to different ultraviolet (UV) light-emitting diode (LED) wavelengths under field conditions. Five UV wavelengths (345, 365, 375, 385, and 395 nm) were tested using six replicated light traps per wavelength in a defoliated forest area in Gunpo, Republic of Korea, over a 4-d period in July 2020. A total of 7,030 adults were captured, of which 90.7% were males and 9.3% were females. Female captures did not differ significantly between wavelengths (F(4, 25) = 2.71, P = 0.0530), indicating limited wavelength-specific attraction. In contrast, male captures differed significantly among treatments (F(4, 25) = 8.69, P = 0.0002), with 385 nm showing the highest attraction efficacy and 345 nm showing the lowest. These results revealed that wavelength selection within the UV range significantly influenced the attraction of male gypsy moths. Overall, these findings provide practical guidance for optimizing UV LED-based monitoring and management strategies for this species.

매미나방(Lymantria dispar Linnaeus)은 돌발적으로 대발생하여 활엽수 및 침엽수에 피해를 주는 주요 산림해충이다. 본 연구는 자외선(UV) LED의 세부 파장에 따른 매미나방 성충의 유인 반응을 비교하기 위해 수행되었다. 345, 365, 375, 385, 395 nm의 5개 파장별 LED 유인 트랩을 각 6반복으로 산림 내에 설치하고 4일간 포획 개체를 조사하였다. 총 7,030개체가 포획되었으며, 수컷이 90% 이상을 차지하였다. 암컷에서는 파장 간 유의한 차이가 나타나지 않았으나(F(4, 25) = 2.71, P = 0.0530), 수컷에서는 파장에 따른 유의한 차이가 나타났으며(F(4, 25) = 8.69, P = 0.0002), 385 nm에서 가장 높은 유인 효과가 확인되었다. 본 연구는 자외선 영역 내에서도 세부 파장 선택이 매미나방 수컷의 유인 효율에 중요한 영향을 미침을 제시하며, LED 기반 모니터링 및 방제 전략 수립에 기초자료를 제공한다.
