합성페로몬에 대한 솔껍질깍지벌레 수컷의 반응에 관여하는 생물적 , 기상적 요인 = Biological and Meteorological Factors Affecting the Responsiveness of Matsucoccus thunbergianae Males to Synthetic Pheromone

다국어 초록 (Multilingual Abstract)

Behavior of Matsucoccus thunbergianae Miller and Park males immediately after emergence from their cocooning site, and meteorological factors affecting the responsiveness of the flying males to synthetic pheromone were studied. On Pinus thunbergii saplings, newly emerged males walked around to locate females. The males lanuched themselves into flight after up to three times of copulation. Without the presence of females, the males took off within five minutes whereas when the females were placed nearby but copulation was artifically prohibited the males did not take off. In a wind tunnel, the presence of female pheromone discouraged male take off. More males were flying in sunny area than in shade, but light intensity had no effect on the responsiveness of males toward the pheromone source. Wind speed was the main meteorological factor that affected the male responsiveness. Most males, after hitting the substrate near pheromone source with various posture, stood on their feet and approached the source.
