在某部营区利用CO2诱蚊器采样的物种优势度与多样性分析

目的了解在部队营区室外环境的不同场所、不同时间使用CO2诱蚊器采样的物种优势度与多样性方法使用CO2诱蚊器采集昆虫,统计昆虫种类与个体数,计算物种优势度、Shannon-Weiner多样性指数和均匀度结果采集到的吸血双翅目昆虫有蚊、蠓和虻蚊、蠓的物种优势度较高吸血双翅目昆虫的优势度可达最高值1.00,最低也达0.57环境复杂性程度高,则物种多样性丰富人为因素和气候因素对物种的优势度、多样性和均匀度均有重要影响结论 CO2诱蚊器采集昆虫对蚊和蠓有较高的特异度,物种多样性与环境关系密切。

Dominance and diversity of species collected using carbon dioxide mosquito traps in a military camp

Objective To identify the dominance and diversity of species collected outdoors using CO2 mosquito traps at different places and times in a military camp. Methods Insects captured using CO2 mosquito traps were analyzed for the species and individual statistics to calculate the dominance, Shannon-Weiner diversity index and evenness. Results Among the collected blood-sucking dipteran insects there were mosquitoes, midges and horseflies. Mosquitoes and midges had higher degrees of dominance. The highest dominance of blood-sucking dipteran insects was up to 1.00, and the lowest 0.57. The higher degree of the environmental complexity, the richer diversity of species was seen. Human and climatic factors also exerted noticeable impact on the dominance, diversity and evenness. Conclusion CO2 mosquito traps have high specificity for mosquitoes and midges. Species diversity is closely related to the environment.
