dc.descriptionThe tropical climate of Brazil favors the presence of the cattle tick Rhipicephalus (Boophilus) microplus throughout the year, especially in the country’s southeastern region. This parasite causes damage to Brazilian livestock through decreasing milk and meat yields and losses relating to leather production and the spread of pathogens of the genera Babesia and Anaplasma. The total economic losses are approximately US$ 3.24 billion per year in Brazil (MELO et al., 2006; GRISI et al., 2014). Rhipicephalus microplus is traditionally controlled through the use of chemical products, often without any technical guidance. This lack of guidance accelerates the selection of resistant strains, and impacts food safety through the presence of chemical residues in products of animal origin (ANDREOTTI et al., 2019).pt_BR
dc.description.abstractThe importance of in-vitro tests using larvae and adults of the tick Rhipicephalus (Boophilus) microplus in investigating new inputs for its biological control serves as a basis for continuation of field experiments. This article presents in-vitro efficacy data on the fungus Purpureocillium lilacinum (IBCB 130) tested using larvae and engorged females of the tick R. microplus according to modified techniques of SHAW (1966) and MONTEIRO (2014). The efficacy results from the tests on engorged females ranged from 99.6 at the highest concentration used (2x109 conidia/mL) to 51% at the lowest concentration (1x107 conidia/mL). The 50, 90 and 99% lethal concentrations found in the tests on larvae were, respectively, 5.1x108, 5.2x109, and 3.3x1011 conidia/mL. The results from this investigation have enabled field experiments to control the tick R. microplus using the IBCB 130 isolate of the fungus P. lilacinum.pt_BR
