County Records for Aedes japonicus in Georgia

Area of Science:

• Entomology
• Vector-borne disease ecology

Background:

• Accurate mosquito species distribution data is crucial for public health and research.
• The invasive mosquito Aedes japonicus (Ae. japonicus) was previously reported in only 7 Georgia counties (2002-2006).
• Limited recent data necessitates an update on Ae. japonicus distribution in Georgia.

Purpose of the Study:

• To consolidate and update the known distribution of Aedes japonicus in Georgia.
• To provide current distributional data for public health use and scientific research.
• To assess the expansion of Ae. japonicus presence across Georgia counties.

Main Methods:

• Compiled existing peer-reviewed records of Ae. japonicus in Georgia.
• Integrated 73 new county records from Georgia Department of Public Health surveillance data.
• Documented the presence of Ae. japonicus in 80 out of 159 Georgia counties.

Main Results:

• Aedes japonicus presence confirmed in 80 Georgia counties, a significant increase from 7.
• Surveillance data revealed a broader distribution than previously documented in peer-reviewed literature.
• The study provides a comprehensive, updated distribution map for Ae. japonicus in Georgia.

Conclusions:

• Ae. japonicus is established in a substantial portion of Georgia, exceeding previous records.
• Updated distributional data is vital for effective mosquito surveillance and control strategies.
• This research serves as a critical resource for understanding invasive species spread in the region.
