In recent decades, the resistance of ticks to acaricides was exacerbated by incorrect use of products, compromising the effectiveness of treatments. This study aimed to determine in vitro effectiveness of commercial acaricides in six populations of Rhipicephalus ( Boophilus ) microplus in northern region of Mato Grosso. On average 100 engorged females were collected from each herd, which were selected and separated into homogeneous groups, sanitized, and immersed to acaricide diluted according to the manufacturer's statement, on sequence there was incubated. After the incubation was obtained from female reproductive efficiency and effectiveness of the tested acaricides. The association cypermethrin+ chlorpyrifos + citronellal showed satisfactory efficiency (> 95%) in all the properties (mean 99.86% in properties), followed by trichlorfon (83.45%), amitraz (72.33%), neem oil (67.23%) and cypermethrin (22.97%), which was not effective in any property. It indicates the use of the association cypermethrin +chlorpyrifos+ citronellal on evaluated properties for control of cattle tick effectively.Read More
