Title : Coffee industry by-products extracts: Evaluation of the repellent effect against the R (B.) microplus tick
Abstract:
Livestock plays a crucial role in the Brazilian economy, however, the ubiquitous presence of the Rhipicephalus (Boophilus) microplus tick represents a significant challenge, resulting in considerable economic losses. Additionally, ticks stand out as vectors of different microorganisms for humans and animals, such as Lyme disease, Babesiosis, Anaplasmosis, Tularemia, and Rocky Mountain spotted fever. This parasite not only impacts animal production, but also increases veterinary care costs, and excessive use of commercial acaricides leads to the development of resistance.
The coffee industry generates by-products that offer an opportunity to explore new repellents. These by-products offer a unique opportunity to explore new tick repellents. In the phytotherapeutic scenario, herbal medicine emerges as a promising alternative for tick repellence. The objective of this study was to evaluate hydroethanolic extracts from by-products of the coffee industry, such as defective roasted beans, defective green beans and leaves, for their repellent effects against R. (B.) microplus. To obtain the extracts, the sonication process was carried out with EtOHH2O 7:3 (v/v), using 500mg of sample for 5mL (plant material/solvent). The repellent activity was evaluated according to the methodology described in the literature.
The extracts were solubilized in Milli-Q water and Tween 2%, at a concentration of 25 mg/mL, and were tested at three-time intervals: 4, 12, and 24 hours of the extracts against ticks. The green grain and leaf extract only showed effects within 4 hours, with 0.6% and 0.7% repellence, respectively. The green grain extract demonstrated effects at intervals of 4 and 12 hours, with 7.8% and 0.6% repellence, respectively. The repellent effects of coffee by-product extracts provide insights for future research at different concentrations, methods of obtaining plant extracts, and tested time intervals, as well as potential associations with biotechnological products. This approach aims to enhance the repellent percentage, enabling its use in tick control in cattle farming.
