    • Abstract:
      A study following the development and migration of Cyathostominae infective larvae was conducted from July 2003 to November 2004 in tropical climate, Baixada Fluminense, RJ, Brazil. Samples of naturally infected feces were placed on 12 m2 plot each month on a cyathostomin-free "Bermuda grass" pasture (Cynodon dactylon). After Seven days, samples of feces and grass were collected every week at 8 a.m, 1 and 5 p.m., weighed and processed by Baermann technique. Higher survival of L3 was found at dry season, 15 and 12 weeks on feces and sward respectively, at rainy season the survival was smaller. The multivariable analysis of main components was evident the influence of time and environment variables on L3 recovery from feces and grass. Close relationship between time and the number of L3 in feces could be noted, in contrast with L3 in sward. The climatic conditions influenced directly the number of infective larvae. The infective larvae were recovered during three times and the Kruskal-Wallis test did not present significance among them.
