【摘要】 报道了黄山风景区松蛀虫种类、主要松蛀虫成虫活动期、种间种群数量比率和种内种群数量垂直分布比率 ,2 0 0 1年 5种松蛀虫成虫种群数量变动规律、不同监测期松墨天牛雌成虫孕卵量及比率。研究结果表明 ,黄山风景区繁衍着 14种松蛀虫 ,主要松蛀虫有 5种 :马尾松角胫象、松墨天牛、短角幽天牛、褐幽天牛、松树皮象。其种群数量比率分别为 6 1.6 %、2 7.0 %、5 .5 %、3.8%和 2 .2 %。松墨天牛成虫最高分布区为海拔 16 5 8m的天海景点 ,海拔 318m的白亭景点种群数量分布比率最高 ,达80 .9% ,诱获的松墨天牛雌成虫平均孕卵量为 2 5 .3粒更多还原

【Abstract】 The pine borer species, action duration of main pine borer, interspecific population density, vertical distribution rate of population density, change law of the population density of 5 pine borer in 2001 , and egg breeding of female pine sawyer, Monochamus alternatus in different trapped duration are described. The results showed that 14 species of pine borer are breeded in Huangshan Scenic Area, of which 5 species are important pine borer, i.e. Shirahoshizo patruelis , M. alternatus , Spondylis buprestoides , Arhopalus rusticus and Hylobius abietis haroldi , occupying 61.6% , 27.0%,5.5%,3.8% and 2.2% of the total species population density respectively. The Tianhai scenic spot (1 658 m above sea level) is the highest zone of the vertical distribution of M. alternatus adult, and the Baiting scenic spot (318 m above sea level) is the distribution zone of the highest population density, occupying 80.9% of the total number trapped. The mean amount of egg developed in ovary of the female M. alternatus trapped is 25.3.更多还原
