          Abstract

          Los objetivos del presente estudio fueron determinar las especies, el número y distribución de garrapatas en regiones corporales y su relación con el total presente en bovinos Criollo Lechero Tropical (CLT). Se utilizaron 28 vaquillas y 16 toretes (655±35 y 741 ±89 d de edad) de un hato experimental ubicado en la región central del estado de Veracruz, México. Las garrapatas saturadas (>4.5 mm) del cuerpo de los bovinos fueron recolectadas, contadas e identificadas por especie. Los datos fueron transformados logarítmicamente y analizados usando un modelo lineal mixto que incluyó los efectos de sexo del animal, especie de garrapata, región corporal y sus interacciones, considerando mediciones repetidas por región corporal. El número de garrapatas de las diferentes regiones corporales se correlacionó con el total mediante la prueba de correlación de Pearson. Las especies de garrapata identificadas fueron Amblyomma cajennense (Ac) y Boophilus microplus (Bm). El total de garrapatas fue 10.6±0.8 Ac, 3.5±0.8 Bm y 14.5±1.15 (Ac+Bm). Aunque las ingles (5.6±0.5) y las axilas (4.4±0.5) fueron las regiones más infestadas, el número de garrapatas del lado izquierdo del cuerpo resultó más correlacionado (R = 0.94) con el número total (p<0.01), por lo que fue identificado como la región corporal más relacionada con la infestación total.

          The objectives of this study were to determine the species, number and distribution on body regions, and their relationship to the total number of ticks on Tropical Milking Criollo cattle. Twenty-eight heifers and 16 young bulls (655±35 and 741±89 d old) from an experimental herd located in the central region of the state of Veracruz, Mexico, were used. Ticks (>4.5 mm) adhered to the body of the cattle were collected, counted and identified by species. The data were transformed logarithmically and analyzed using a mixed linear model that included the effects of animal sex, tick species, body region, and their interactions, considering repeated measurements by body region. The number of ticks on different body regions was correlated with the total number of ticks with a Pearson correlation test. The tick species identified were Amblyomma cajennense (Ac) and Boophilus microplus (Bm). The total number of ticks was 10.6±0.8 Ac, 3.5±0.8 Bm, and 14.5±1.15 (Ac+Bm). Although the most infested body regions were the groin (5.6±0.5) and axilla (4.4±0.5), the number of ticks on the left side of the body correlated more highly (R=0.94) with the total number (p<0.01). Thus, the left side was identified as the body region most related to total infestation.
