솔나방의 light-trap에 의한 유인력 비교와 시간별 유인효과, 유인되는 성간비교 및 유아등종의 개발과 trap형에 고나한 실험에서 다음과 같은 결과를 얻었다. 1. 솔나방의 인인성은 U.V. 파장 에서 가장 유인효과가 좋았다. 2. 솔나방의 유인 최성시각은 20:00-22:00시로서 그때의 유인수는 전체 유인수의 가 이 시각에 유인되었다. 3. 적색, 황색등에서는 유인효과를 볼수 없었다. 4. Blacklight-trap의 경우 20:00-22:00시까지 유인되는 성비는 로서 female의 유인수가 더 많았다. 5. 기상조건과 솔나방의 유인효과와는 상관관계가 없었다.

This experiment was conducted to determine the most effective type of Bight·trap for pine catepillar moths (Dendrolimus spectabilis B.) and to investigate the environmental factors affecting the attractiveness of the moths.. The various types of light traps made used of: black light, white light, fluorescent light, yellow light, and red light and the environmental factors considered were rainfall, wind velocity and collecting time. All the traps were operated from 8 in the evening to midnight. The results obtained are summarized as follows, The most effective attraction of moths ( of total number attracted) was observed with blacklight-lamp and the most abundant attraction of the moths was found from 8 to 10 in the evening. Attractiveness in terms of sex ratio attracted from 8 to 10 in the evening was found to the .approximately 7 female to 1 male, Environmental factors considered were found to have no influences in attractiveness of the moths in this experiment.
