Resumo: | The objective of this work was to determine the population fluctuation of reniform nematodes (Rotylenchulus reniformis) in a cotton production area as affected by soil and climate conditions. A grid of 30 sampling sites, equidistant in 50 m from each other, was established in a field naturally infested – with an average of 680 reniform nematodes per 200 cm3 soil, in Aral Moreira county, Mato Grosso do Sul, Brazil. Soil samples at 0.0–0.2 and 0.2–0.4 m depths were collected monthly on each sampling site, between October 2004 and June 2006, for the evaluation of nematode abundance and population composition. Measurements of soil temperature and moisture at 0.15 and 0.30 m depth and rainfall were made in each sampling site. It was observed that cotton plants play important roles in the abundance and composition of reniform nematode populations. The abundance of R. reniformis was higher at 0.2–0.4 m depth. Rainfall and soil moisture contents had little influence on reniform nematode population. Soil temperatures at both 0.15 and 0.30 m were correlated to R. reniformis population density at 0.2–0.4 m depth. |

Em uma área naturalmente infestada – com média de 680 nematoides por 200 cm3 de solo, em Aral Moreira, MS – foi estabelecida uma grade de amostragem com 30 pontos, equidistantes em 50 m. No período de outubro de 2004 a junho de 2006, amostras de solo (0,0–0,2 m e 0,2–0,4 m) foram coletadas mensalmente, para avaliação da abundância e composição dos diferentes estágios da população do nematoide. Foram também mensuradas a precipitação, a temperatura e a umidade do solo a 0,15 e 0,30 m. Foi possível observar que a densidade e a composição populacional de R. reniformis são influenciadas pela presença de plantas de algodoeiro. Maior abundância desse nematoide foi encontrada à profundidade de 0,2–0,4 m. A precipitação e a umidade do solo pouco influenciaram a população de R. reniformis. A temperatura do solo, a 0,15 e 0,30 m de profundidade, correlaciona-se com a população de R. reniformis a 0,2–0,4 m de profundidade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFUNDECT e CNPqAsmus, Guilherme LafourcadeIshimi, Cassiana Miki2009-03-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/1417Pesquisa Agropecuaria Brasileira; v.44, n.1, jan. 2009; 51-57Pesquisa Agropecuária Brasileira; v.44, n.1, jan. 2009; 51-571678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/1417/5628https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1417/972https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/1417/973info:eu-repo/semantics/openAccess2014-11-18T17:36:01Zoai:ojs.seer.sct.embrapa.br:article/1417Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-11-18T17:36:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
