福建省武夷山自然保护区竹林的白纹伊蚊垂直分布及蚊种组成(双翅目:蚊科)

VERTICAL DISTRIBUTION OF AEDES ALPOPICTUS AND COMPOSITION OF MOSQUITO POPULATIONS IN BAMBOO FOREST OF WUYISHAN NATURE RESERVE,FUJIAN PROVINCE (DIPTERA:CULICIDAE)

白纹伊蚊(Aedes albopictus)是我国登革热及多种蚊媒病毒的重要潜在媒介。为了进一步了解该蚊在武夷山区的垂直分布特点及其与人居的关系,以便为蚊媒综合防制提供生态学依据,我们于1984年7—8月在武夷山自然保护区中心三港一带,对不同海拔高度竹林区的孳生蚊类进行调查。现将调查结果,报道于下。

Four bamboo forests at different altitudes in Wuyi mountain were sur veyed for the presence of Aedes albopictus from July to August in 1984.This mosquito was found in residential area from low altitude up to 800m above sea level.It was not found in bamboo forest in inhabited region at higher altitude(950-1250m). Larvae of 6 genera and 16 species of mosquitoes had been collected from bamboo-holes,among which Aedes fengi was the dominant one.It occurred in 602 out of 828 bamboo-holes examined,with a frequency of 72.71%.
