Artigo recente: Susceptibility of Rhipicephalus (Boophilus) microplus to fluazuron (2.5 mg/kg) and a combination of novaluron (2.0 mg/kg) + eprinomectin (0.36 mg/kg) in field studies in Brazil

Este artigo foi recentemente publicado na Preventive Veterinary Medicine Volume 135, 1 December 2016, Pages 74–86, e traz os seguintes Highlights:
