[Method of determination of population density of the Aedes (Culicidae)]
Abstract:
For 6 years 16 species of the genus Aedes were recorded from the territory of Leningrad. To judge by the per cent ratio between mosquitoes and their larvae, such species as A. caspius dorsalic and A. flavescens such blood of man unwillingly and A. cantans and A. cinereus attack man in general. The abundance of Aedes population within the territory of Leningrad was estimated on the number of pupae per 1 m2 in various types of water bodies for the whole reproduction season by means of multiplication of the number of papae per 1 m2 by the whole area where aquatic stages of mosquitoes were observed.
Insights
Sixteen Aedes mosquito species were found in Leningrad over six years. Key species like Aedes caspius dorsalis and Aedes flavescens rarely bite humans, while Aedes cantans and Aedes cinereus frequently do.
Area of Science:
- Entomology
- Medical Zoology
- Ecology
Context:
- The study was conducted in Leningrad over a six-year period.
- Sixteen species of the genus Aedes were identified.
- Mosquito population dynamics are crucial for public health in urban environments.
Purpose:
- To document the species diversity of Aedes mosquitoes in Leningrad.
- To assess the biting behavior of different Aedes species towards humans.
- To establish a method for estimating Aedes mosquito population abundance.
Summary:
- A six-year survey in Leningrad identified 16 Aedes mosquito species.
- Analysis of larval and adult ratios indicated that Aedes caspius dorsalis and Aedes flavescens infrequently bite humans, whereas Aedes cantans and Aedes cinereus readily attack humans.
- Aedes mosquito population abundance was estimated by multiplying pupal density per square meter by the total area of aquatic habitats.
Impact:
- Provides baseline data on Aedes mosquito species distribution in Leningrad.
- Informs public health strategies for mosquito-borne disease prevention.
- Offers a standardized methodology for Aedes population assessment in urban ecosystems.
