A detector dog for screwworms (Diptera: Calliphoridae)

Area of Science:

• Veterinary Entomology
• Animal Behavior
• Pest Detection

Background:

• The screwworm (Cochliomyia hominivorax) is a significant economic and agricultural pest.
• Effective detection methods are crucial for preventing the reintroduction of screwworms into previously eradicated areas.

Purpose of the Study:

• To train a German wirehaired pointer to detect screwworm pupae and infested animals.
• To evaluate the efficacy and success rate of a trained detector dog in identifying screwworms.

Main Methods:

• A German wirehaired pointer was trained using specific commands to locate screwworm-infested animals and pupae.
• The dog's detection abilities were assessed over several months using training dummies and live infested animals.

Main Results:

• The dog achieved a 100% success rate in detecting screwworm-infested animals after 5 months of training.
• After an additional 3 months, the dog could also detect screwworm pupae with high accuracy.
• The overall success rate reached 99.7% across 286 tests.

Conclusions:

• Detector dogs represent a highly efficient and accurate tool for identifying screwworms.
• Implementing detector dogs at quarantine stations can enhance efficiency, reduce costs, and prevent screwworm reintroduction.
