Identificación taxonómica de garrapatas en ganado bovino del cantón Gonzanamá

Ticks are ectoparasites that affect the profitability of livestock production units in tropical, subtropical and temperate regions of Ecuador, not only because of the direct damage they cause to animals, but also because of the diseases they transmit, affecting public and veterinary health. The objective of this research was to taxonomically identify the ticks present in cattle in the canton of Gonzanamá. We collected 400 tick samples directly from cattle (parasitic phase) and 107 samples from pastures through transects (non-parasitic phase). A total of 507 ticks were morphologically identified using taxonomic keys and a stereomicroscope, of which 78.9 % (400) were in the parasitic phase and 21.1 % (107) in the non-parasitic phase. According to the species, Rhipicephalus Boophilus microplus was identified in 19/20 (95 %) farms and Amblyomma maculatum in 1/20 (5 %) farms. On the other hand, of the 107 ticks collected in the pasture, 75.7 % (81) were in the nymph stage and 24.3 % (26) were larvae. In both evolutionary stages, the species identified was Rhipicephalus (B) microplus in 100 % (20/20) of the farms sampled. Spatial distribution maps were also prepared, which showed that these tick species were found at temperatures ranging from 16 to 24 °C, with a rainfall of 600 mm to 1100 mm, and at altitudes ranging from 1500 to 3000 m a.s.l., especially in the parishes of Nambacola, Purunuma and Gonzanamá. Finally, and considering this problem, it is important to emphasize that tick control in livestock farms is essential to guarantee the health and welfare of livestock, prevent economic losses, protect human health and avoid resistance to anti-parasitic treatments.
