Abstract

The attraction effects of light emitting diode (LED) trap to Spodoptera exigua and Spodoptera litura adults were evaluated in greenhouse and compared with those of no light trap, which is typical used in commercial trap. At this time, in order to attract these two species of moths, sex pheromone traps were installed at the top side according to the degree of tomato growth inside the tomato cultivation greenhouse around the LED trap. In addition, two types of light-emitting traps (420 nm, 470 nm) were installed in the greenhouse at 1/40 m2, respectively. Also two sex pheromone were installed inside of the greenhouse according to the height of the tomato plants. 10 days later, Blue-light trap(BLB, 470 nm wavelength) was 3.1-3.5 times more attractive than Violet-light trap(VLB, 420 nm wavelength) in S. exigua (105.6 ± 7.3) and S. litura (42.0 ± 3.1) respectively, whereas the no-light trap was little attractive to S. exigua (33.7 ± 2.8) and S. litura (12.0 ± 1.5). On the other hand, after the installation of the sex pheromone trap and the LED trap, there was no damage to S. litura (Fabricius) and S. exigua in the pesticide-free area, indicating a high possibility of control. At this time, the operating cost of the two types of LED traps was 80 won/m2 per unit area, and it was confirmed that both types of moths could be controlled. In addition, as a result of confirming the number of two types of moths caught in the sexual pheromone trap and two types of LED traps after 4 months, it was judged that eco-friendly control was possible as more than 373 moths/trap were attracted to the two types of moths.

토마토 재배지에서 다발생하는 파밤나방(S. exigua)과 담배거세미나방(S. litura) 유인살충을 위해 두 종류의 LED 트랩을 온실 외부에 설치하고 no light 트랩을 대조구로 하여 트랩내 유인력을 상호 비교하였다. 이때 이들 두 종의 나방류 유인을 위해 LED 트랩 주위 토마토 재배온실 안쪽에 토마토의 생장 정도에 따라 상부에 성페로몬 트랩을 각각 설치하였다. 설치 10일 후 LED 트랩에서 두 종의 나방이 다량 유인되었으나 no light 트랩에서는 두 종의 나방류 유인력이 매우 낮았다. 또한, 두 종의 나방이 유인된 LED 트랩 간 유인량 비교 결과 Violet-light 트랩(VLB trap, 파장범위 420nm)에서는 담배거세미나방 12마리, 파밤나방 34마리가 유인된 반면, Blue-light 트랩(BLB trap, 파장범위 470nm)에서는 42마리와 105마리가 유인되어 3.1-3.5배 높게 유인되었다. 한편, 성페로몬 트랩과 LED 유인 트랩 설치 후 살충제 무처리구에서 파밤나방과 담배거세미나방 피해가 발생하지 않아 방제 가능성이 높은 것으로 나타났다. 이때 2종의 LED 트랩의 운용비용은 단위 면적당 80won/m2으로 나타났으며, 두 종의 나방 모두 방제가 가능한 것으로 나타났다. 또한 성페로몬 트랩과 2종의 LED 트랩에서 포획된 토마토 가해 두 종의 나방 수를 4개월 후 확인해 본 결과, 두 종의 나방이 373마리/트랩 이상 유인되어 친환경적인 방제가 가능한 것으로 판단되었다.
