The parasitism of cattle by <em>Rhipicephalus microplus</em>, causes great economic losses to the producers in the area. The resistance of <em>R. microplus</em> to macrocyclic lactones class has been detected in Rio Grande do Sul, Brazil since 2001. Side-resistance (i.e. resistance to one compound accompanied by resistance to other members of the chemical group) among the drugs of this class is an important condition, considering its implications in resistance management and cattle tick control strategies using these acaricides. The aim of this study was to evaluate the occurrence of side-resistance among ivermectin (IVM), doramectin (DOR), and moxidectin (MOX) in <em>R. microplus</em> from different locations of Rio Grande do Sul state, southern Brazil. Engorged female ticks were sampled in 30 different premises and their larval progeny were tested with the larval immersion test. A macrocyclic lactone resistant reference strain (IPVDF strain) was also submitted to the assays. Mortality data was submitted to probit analysis to calculate the median lethal concentrations (LC₅₀) for each acaricide. Resistance ratios (RR) were calculated in relation to the Porto Alegre strain, being considered resistant the populations with RR ≥ 2. Fisher's test was used to determine the correlation of resistance among the drugs tested. Among the 30 isolates tested, 57 % (<em>n</em> = 17) were resistant to ivermectin (RR: 2.06 to 17.81); 47 % (<em>n</em> = 14) resistant to doramectin (RR: 2.07 to 19.03) and 30 % (<em>n</em> = 9) resistant to moxidectin (RR: 2.00 to 17.28). Nine samples were susceptible to all three acaricides. There was association of the occurrence of resistance between IVM and DOR (<em>p</em> = 0.02), between IVM and MOX (<em>p</em> = 0.015) and between DOR x MOX (<em>p</em> = 0.019). This is the first study to demonstrate side-resistance among drugs of the macrocyclic lactones family of anti-parasitic drugs in <em>R. microplus</em> from south Brazil. The results obtained reinforce the importance of acaricide resistance detection with laboratory bioassays and have an impact on cattle tick control strategies, since side-resistance among the macrocyclic lactones limits the availability of drugs to be used.</div></div>","PeriodicalId":23600,"journal":{"name":"Veterinary parasitology, regional studies and reports","volume":"67 ","pages":"Article 101405"},"PeriodicalIF":1.4,"publicationDate":"2025-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145798598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
