摘　　要：为研究海拔高度对松褐天牛羽化规律的影响,利用ZM-60型诱捕器监测松褐天牛羽化规律,并进行了诱捕试验。结果表明,松褐天牛羽化始见期、始盛期、高峰期、盛末期和终见期随海拔高度的升高而向后延迟。海拔100 m与900 m的始见期和终见期分别相差16 d和12 d;随着海拔高度的上升,始盛期羽化数量增加,高峰期和盛末期数量减少。不同海拔高度松褐天牛羽化均出现两个高峰。其中海拔100m的第一个高峰高于第二个高峰;海拔300 m、500 m、700 m和900 m的第一个高峰均低于第二个高峰。In this paper,in order to study the effects of altitudes on the eclosion regularities of Monochamus alternatus,Model ZM-60 Trapper was used to monitor the eclosion regularities of the species and a trapping experiment was carried out.The results showed that the beginning,pre-prime stage,prime stage,post-prime stage and end of the eclosion were delayed along with the increase of the altitude.The beginning and end of the eclosion at Altitude 100 m were 16 d and 12 d earlier respectively than those at Altitude 900 m;with the increase of the altitude,the eclosion number increased at pre-prime stage,and decreased at both the prime stage and post-prime stage.2 peaks appeared in the eclosion of the species at all the altitudes,and the first peak was higher than the second peak at Altitude 100 m,but lower than the second peak at Altitudes 300 m,500 m,700 m and 900 m.
