Resumo: Survival and migration of infective larvae of cattle parasite gastrintestinal nematodes observed on a pangola grass (Digitaria decumbens) pasture exclosure, where dung pats were monthly placed. At 25 to 35 days intervals the dung pat and the surrounding vegetation were analysed for presence and quantity of infective larvae. It was concluded that, in the studied region, the dung pat offers survival conditions to free living forms during the dry season. Infective larvae migration increased with rainfall, proportionally to intensity and frequency of rains. From the total of pasture recovered larvae, 66% belonged to the genus Cooperia, 17,3% to Haemonchus and 16,5% were identified as Oesophagostomum sp. larvae of Trichostrongylus occurred in inexpressive numbers.

A partir da deposição, em intervalos de 25 a 35 dias, o bolo fecal e a vegetação ao seu redor foram analisados quanto à presença e quantidade de larvas infectantes. Concluiu-se que, na região estudada, durante a estação seca, o bolo fecal oferece condições à sobrevivência das formas de vida livre. A migração das larvas infectantes dos bolos fecais para o pasto aumentou quando houve precipitação pluviométrica e o aumento foi proporcional à intensidade e frequência das chuvas. Do total de larvas recuperadas no pasto, 66% foram do gênero Cooperia, 17,3% de Haemonchus e 16,5% identificadas como Oesophagostomum sp. larvas de Trichostrongylus ocorreram em números inexpressivos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCatto, João Batista2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15948Pesquisa Agropecuaria Brasileira; v.17, n.6, jun. 1982; 923-927Pesquisa Agropecuária Brasileira; v.17, n.6, jun. 1982; 923-9271678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/15948/10062info:eu-repo/semantics/openAccess2014-04-16T13:42:01Zoai:ojs.seer.sct.embrapa.br:article/15948Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T13:42:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
