  Para cuantificar la influencia de la presencia animal en la recuperación de larvas de pastos infestados experimentalmente, se realizó un ensayo en otoño 1999 e invierno 1999-2000. Para ello se compararon 4 formas de muestreo y 3 tipos de pastos. No hubo diferencias en la recuperación de larvas entre las 4 formas, pero si, entre los tipos de pastos (p < 0,05)

  To quantify the influence of the animal presence on the percentage of Boophilus microplus larvae recovery from plots experimentally infested with this tick, it was carried out a trial in Jiutepec, Morelos, Mexico, during autumn 1999 and winter 1999-2000. For this purpose there were compared four sampling methods: human walking with chaps, bovine dressed walking, double walking flagging and double walking with baited flagging. The comparison was made on tree grasses: Andropogun gayanus(gamba), Cenchrus ciliaris (buffel) and Melinis minutiflora (molasses). It was observed the same recovery efficiency of B. microplus larvae in the four sampling methods studied in the two seasons. There were no statistical differences, although, there were differences (P < 0.05) among the grass species. The higher number of larvae recovered was recorded in the low third of the chaps, in the head and front legs of the bovine dressed, from the buffel grass and on the ventral region and legs in the other two grasses
