Ticks (Acari: Ixodidae) in Bulloch County, Georgia

Area of Science:

• Veterinary Entomology
• Parasitology
• Wildlife Ecology

Background:

• Tick-borne diseases pose significant risks to animal and human health.
• Understanding local tick populations and their hosts is crucial for effective disease surveillance and control.

Purpose of the Study:

• To comprehensively assess tick species composition in Bulloch County, Georgia.
• To investigate the seasonal activity patterns of various tick species.
• To identify and analyze host-tick associations within the study area.

Main Methods:

• An 18-month study employed seven diverse tick collection methods, including live trapping, drag sampling, and CO2 attraction.
• Ticks were collected from a wide array of sources: wild game, livestock, road kills, nests, burrows, and submissions from veterinarians and residents.
• A total of 55 animal species were examined for tick parasitism.

Main Results:

• Twelve tick species (family Ixodidae) were identified.
• The blacklegged tick (Ixodes scapularis) and American dog tick (Dermacentor variabilis) were the most abundant and exhibited the broadest host ranges.
• White-tailed deer (Odocoileus virginianus) were found to support the highest number of tick species (five).
• Ticks parasitized 16 mammal, 5 bird, and 3 reptile species.

Conclusions:

• The study provides a detailed ecological profile of ticks in Bulloch County, Georgia.
• Ixodes scapularis and Dermacentor variabilis are key species in this region due to their prevalence and host associations.
• Findings underscore the importance of wildlife, particularly white-tailed deer, in supporting diverse tick populations.
