中国龟象亚科分布概况(鞘翅目,象虫科)

THE DISTRIBUTION OF CEUTORHYNCHINAE IN CHINA (COLEOPTERA, CURCULIONIDAE)

基于对中国龟象亚科标本信息的系统整理,得出龟象在中国各省均有分布,但分布的多少很不均衡,其中福建省最丰富,达到标本总数的36.6%。分布范围为18.6～51.7°N,最南端到海南省的保亭,最北为黑龙江省的大兴安岭,从热带、亚热带到温带均分布,其中26～30°N最丰富,占总数的47.7%。中国龟象生存的海拔范围记录为10～4400m,最低海拔采集点位于海南省万宁,最高海拔位于四川省乡城中热乌,500～1000m海拔范围的龟象标本数量最多,随着海拔高度的上升,数量逐步减少。多数龟象标本采集于5月到8月,随着纬度的上升,采集时间逐渐从4月到9月缩减为6月到8月。

We studied on the distribution of subfamily Ceutorhynchinae collected from China with the GIS software （Arcview 3.2）. The latitudinal, altitudinal, seasonal and chronological distribution characters are studied throughout China. Ceutorhynchinae distributes in every province of China. The abundance of different provinces is varied, while the most abundant area is Fujian Province which shows the relative occupying ratio as 36.6%. The latitudinal distribution range of Ceutorhynchinae in China is 18.6-51.7°N, from Baoting in Hainan Province to Daxinganling in Heilongjiang Province, including the tropics,subtropics and temperate zone. The range of 26° N- 30°N is the most abundant area, occupying ratio as 47.7%, The altitudinal distribution range is 10- 4 400 m, the lowest record is at Wanning in Hainan Province and the highest record is at Xiangcheng in Sichuan Province. The most abundant range is 500- 1 000 m. The abundance decreases gradually as the altitude rises. Most of the specimens were collected from May to August. The active season is from April to September in low altitude area, while from June to August in high altitude area.
