Resumo: Rhipicephalus (Boophilus) microplus infestation is responsible for significant economic losses in cattle industry. The use of acaricides at strategic times and selection of resistant animals can minimize economic losses. This study aimed to determine the anatomical distribution and population dynamics of R. microplus in the municipality of Óleo, state of São Paulo. This study was conducted using eight male cattle, crossbred zebu-taurine (in accordance with the regional herd). Female R. (B.) microplus, greater than 4 mm, present in the right side of the animals were counted between April 2012 and March 2013. The highest tick number per animal was noted in October (128.25), and the lowest in April (35.5), with three infestation peaks during the study, in May, October, and December, which were influenced by the minimum and maximum mean temperature and rainfall. Among the cranio-caudal regions (anterior, median, and posterior), the posterior had the highest mean tick number, and the anterior had the lowest. The minimum temperature, rainfall, and solar radiation interfered with infestation of dorsoventral regions: in cold months, the lowest infestations were found in the mixed area (ear and tail); in the warm months, in the high region (head, neck, upper ribs, flank, and rump). The lower region (dewlap, cranial limb, lower ribs, abdomen, prepuce, scrotum, and lower limb) always had the highest mean tick number. The tick numbers of the caudal limb and crotch showed strong correlation with the total tick number (+0.88 and +0.70, respectively). These data, grouped according to median, posterior, and crotch regions, showed a stronger correlation with the total tick number (+0.96, +0.90, and +0.70, respectively).

O uso de acaricidas de forma estratégica e a seleção de animais mais resistentes podem minimizar os prejuízos econômicos. O objetivo deste estudo foi determinar a distribuição anatômica e a dinâmica populacional do carrapato em bovinos do município de Óleo, SP. O estudo foi conduzido com 08 bovinos machos, mestiços zebu-taurino (conforme rebanho regional). Foram contadas as fêmeas de R. (B.) microplus, maiores que 4 mm, existentes no lado direito do animal, a cada 4 semanas, no período entre abril de 2012 e março de 2013. Obteve-se o maior número de carrapatos por animal em outubro (128,25), e o menor em abril (35,5), com a existência de três picos de infestação, sendo eles nos meses de maio, outubro e dezembro. Verificou-se a existência de três gerações anuais de carrapatos, que foram influenciadas pela precipitação pluviométrica e temperatura média, mínima e máxima. Das regiões Crânio-caudal (anterior, mediana e posterior), a posterior obteve o maior número médio de carrapatos e a anterior o menor. A temperatura mínima, a pluviosidade e a radiação solar interferiram nas infestações das regiões Dorso-ventral, nos meses frios, as menores infestações foram encontradas na área mista (orelha e cauda) e nos meses quentes na alta (cabeça, pescoço, costado alto, flanco e garupa). A região baixa (barbela, membro cranial, costado baixo, ventre, prepúcio, membro caudal e bolsa escrotal) se manteve sempre com a maior média. Das diferentes regiões anatômicas estabelecidas, o número de carrapatos do membro caudal e entrepernas mostraram ter forte correlação com o total, +0,88 e +0,70, respectivamente. Esses mesmos dados, agrupados segundo regiões previamente estabelecidas, obtiveram correlação mais forte com o total de carrapatos, sendo +0,96 (mediana), +0,90 (posterior) e +0,70 (entrepernas).UEL2018-05-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2991610.5433/1679-0359.2018v39n3p1077Semina: Ciências Agrárias; Vol. 39 No. 3 (2018); 1077-1090Semina: Ciências Agrárias; v. 39 n. 3 (2018); 1077-10901679-03591676-546Xreponame:Semina.
