A self-medicating applicator for control of ticks on deer

Area of Science:

• Veterinary Entomology
• Wildlife Management
• Pest Control Technology

Background:

• Tick-borne diseases pose significant threats to wildlife and domestic animals.
• Current tick control methods often involve direct application, which can be challenging for wild populations.
• Developing passive, self-medicating delivery systems for acaricides is crucial for effective tick management.

Purpose of the Study:

• To describe and evaluate a novel self-medicating applicator for passive acaricide transfer to control ticks on ungulates.
• To assess the efficacy of the applicator in reducing tick loads on white-tailed deer and penned goats.
• To confirm animal utilization and acaricide transfer via hair sample analysis.

Main Methods:

• The applicator features a food bin and a sealed acaricide reservoir with a ceramic column for passive transfer.
• Field studies involved hunter-killed deer from treated and control sites to compare Ixodes scapularis infestation.
• Laboratory studies used penned goats infested with Amblyomma americanum to determine treatment efficacy and permethrin presence in hair samples.

Main Results:

• Hunter-killed deer from treated sites had significantly fewer Ixodes scapularis (3.4 +/- 1.1) compared to control sites (10.8 +/- 3.0).
• Permethrin was detected in the hair of treated deer and goats, confirming acaricide uptake.
• In goats, treatment efficacy reached 86.4% within 4 days, with all animals observed using the applicators.

Conclusions:

• The self-medicating applicator is a viable tool for passive tick control in white-tailed deer and domestic ungulates.
• The device demonstrates significant potential for reducing tick burdens in wildlife and livestock.
• Further research can optimize this technology for broader application in animal health and disease prevention.
