摘　　要：利用不同波长的灯具对阜新市赤松毛虫成虫开展灯诱筛选试验,结果表明,21:30时所有供试诱虫灯诱杀到的松毛虫雌虫数量和雌雄成虫总量最多,22:30时诱杀到的赤松毛虫雄虫数量最多。诱集总量由多至少的波长序号为:2号>19号>4号=5号>7号。灯诱赤松毛虫成虫的最佳上灯时间为21:00～23:00时,从而为生产防治提供了最佳波长和上灯时段。Proved by light wap experiments of Dendrolimus spectabilis adults by using lights with different wavelengths, the greatest number of male Dendrolimus spectabilis and female Dendrolimus spectabilis was trapped at nine thirty p.m.; the greatest number of male Dendrolimus spectabilis was Wapped at ten thirty p.m.; and based on the total amount of Wapped Dendrolimus spectabilis adults, the serial numbers of wavelengths were ranked as follows： No.2〉No. 19〉 No. 4=N0.5〉No.7. It concluded that the optimal light trap time inter- val of Dendrolimus spectabilis adults was from nine p.m. to eleven p.m.; and therefore, the optimal wavelength and the optimal light Wap time interval are discovered for production and prevention of Dendrolimus spectabilis adults.
