Abstract:

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.
