我国15种蚊虫雌蚊尾器的形态特征观察

Taxonomic study on fifteen species female mosquito terminalia of China(Diptera: Culicidae)

目的对我国广东省野外采集的15种蚊虫雌蚊尾器进行形态和分类学观察并探讨其分类学意义。方法自雌蚊腹部剪下腹节最后两节,经KOH浸泡过夜后,酒精脱水、二甲苯透明,加拿大树胶封片后显微镜下观察。结果上述15种蚊虫形态分类学特征不同。结论利用雌蚊尾器区分蚊虫种类是一种有效的分类学手段,在蚊虫调查研究中有分类学实用价值。

Objective To observe the terminalia of adult female mosquito and explore taxonomic method for mosquito identification. Methods The last two abdomen segments of mosquitoes were cut down and treated with KOH, alcohol and xylene. Then the samples were observed under Nikon light microscope after sealed with neutral balsam on slides. Results The female terminalia of fifteen species mosquitoes can be identified according to different morphological characters. Conclusion Morphological characteristics female terminalia can be used on mosquito taxonomic study as a useful complementary method especially when male mosquito is not available in field.
