Resumo: Aiming to determine development and longevity of infective larvae of nematodes of cattle, dung pads were placed on Digitaria decumbens and on native pasture during two years, in the Pantanal region. After placement the dung pad and the pasture were regularly analysed for presence of L3. It was observed that during the dry season, mainly at the start, the dung pads and the surrounding forage stayed positive for presence of infective larvae for up to six months, while the ones placed during the most raining months remained with L3 no longer than two months. The results were similar for the forage. It is concluded that in the Pantanal region the free life form finds conditions for development and survival within the dung pad. Larvae migration from the dung pad to the pasture is intermittent, mainly during the dry season. During the raining season, the liberation to the pasture is faster, due to high humidity and direct action of dung beetles and heavy rains.

Após a deposição, regularmente, o bolo fecal e a pastagem foram analisados quanto à presença de L3. Observou-se, durante e principalmente no início da estação seca, que os bolos fecais e a pastagem ao seu redor permaneceram positivos à presença de larvas infectantes, por até seis meses, ao passo que os depositados na estação chuvosa durante os meses de máxima precipitação mantiveram-se com L3 no máximo por dois meses. No pasto, os resultados foram semelhantes. Conclui-se que na região do Pantanal, durante todo o ano, as formas de vida livre encontram condições para se desenvolver e sobreviver no bolo fecal. A migração das larvas do bolo fecal para o pasto é fracionada, principalmente durante a estação seca. Na estação chuvosa, graças à umidade alta e à ação direta de coleópteros coprófagos e precipitações elevadas, a liberação para o pasto é mais rápida.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCatto, João Batista2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14889Pesquisa Agropecuaria Brasileira; v.22, n.8, ago. 1987; 847-854Pesquisa Agropecuária Brasileira; v.22, n.8, ago. 1987; 847-8541678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14889/8599info:eu-repo/semantics/openAccess2014-10-08T20:00:19Zoai:ojs.seer.sct.embrapa.br:article/14889Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-08T20:00:19Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
