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.

톱다리개미허리노린재(Riptortus pedestris)는 콩을 비롯하여 단감, 사과 등의 과수에도 피해를 주는 주요 해충이다. 톱다리개미허리노린재의 방제를 위해 페로몬을 이용한 유인 트랩-통발트랩이 사용되고 있다. 통발트랩의 경우 좋은 유인-포획률을 보이지만, 페로몬에 유인된 톱다리개미허리노린재가 트랩안에 들어가기 까지 시간이 걸리고, 일부는 트랩 안으로 들어가지 않는 단점이 있다. 이에 이러한 단점을 극복하고 포획 효율을 높이기 위해, 새로운 형태의 트랩-피라밋 트랩과 윙트랩(대칭트랩)을 개발하여 그 효율을 확인하였다. 단감원에서의 3주간 포획실험 결과, 기존의 통발트랩보다 피라밋 트랩은 6배, 윙트랩(대칭트랩)은 28배 이상의 톱다리개미허리노린재가 포획되었다. 이에 본 발표에서는 높은 포획 효율을 보인 피라밋 트랩과 윙트랩(대칭트랩)의 소개 및 이용법에 관하여 고찰하고자 한다.

Without pesticide applications, mass-trapping by sex pheromone was successful to control Spodoptera litura (Fabricius) in a large scale tomato glasshouse (10,000 ㎡) at a low cost of 60 won/㎡. Pheromone traps were placed both inside and outside of the glasshouse. Inside the glasshouse traps were installed in a regular space, one trap per 500 ㎡, to catch the moths that were present in the glasshouse, and traps were also set outside of the glasshouse, at intervals of ca. 20 m, to prevent the moths from invading the glasshouse. In the experiment, more than 400 S. litura were captured per trap.
