The fleas (Siphonaptera) of Tennessee

Area of Science:

• Entomology
• Parasitology
• Zoology

Background:

• Fleas (Siphonaptera) are important ectoparasites and disease vectors.
• Previous documentation of flea fauna in southeastern states is limited.
• Tennessee's diverse habitats may support a rich flea diversity.

Purpose of the Study:

• To document the flea species present in Tennessee.
• To identify new state records for flea species.
• To assess the abundance and distribution of common flea species.

Main Methods:

• Field surveys and specimen collection across Tennessee.
• Species identification using taxonomic keys.
• Comparison of Tennessee's flea fauna with other southeastern states.

Main Results:

• A total of 33 flea species were recorded in Tennessee.
• New state records were established for Euhoplopsyllus glacialis affinis and Pulex simulans.
• Ctenocephalides felis and Ctenophthalmus pseudagyrtes were found to be widespread and abundant.

Conclusions:

• Tennessee possesses a relatively rich flea fauna compared to surrounding southeastern states.
• Boreal flea species are present in higher elevations of the Appalachian Mountains.
• Common flea vectors, including Ctenocephalides felis, inhabit Tennessee and pose a nuisance to companion animals and humans.
