Amazonian Tree Residue Shows Potential as Natural Tick Control Alternative

SANTARÉM, Brazil - Sept. 5, 2025 - PRLog -- Researchers at the Federal University of Western Pará (UFOPA) have discovered that industrial residue from the Amazonian tree Carapa sp. (commonly known as andiroba) demonstrates strong acaricidal activity against the tick Dermacentor nitens. The findings, recently published in the international journal Veterinary Sciences, highlight the potential of natural plant-derived compounds to replace synthetic chemicals in veterinary parasite control.

The study, led by Professor Antonio Humberto Hamad Minervino of UFOPA's Laboratory of Animal Health (LARSANA), evaluated extracts obtained from the industrial byproducts of andiroba oil production. Results showed significant larvicidal activity, particularly at concentrations of 5% and 10%.

Although higher concentrations demand large amounts of plant material, Minervino emphasizes that the research underscores the importance of Amazonian biodiversity as a source of bioactive molecules with potential applications in animal health and sustainable agriculture. The study also points to the need for isolating and characterizing active compounds to enable the development of effective formulations at lower, more viable doses.

"Industrial residues of andiroba, traditionally discarded, could become a valuable resource for sustainable parasite control, reducing environmental impacts while supporting Amazonian livestock production," said Professor Antonio Minervino.
