Resumo: The objectives of this work were to assess phosphine resistance in insect populations (Tribolium castaneum, Rhyzopertha dominica, Sitophilus zeamais and Oryzaephilus surinamensis) from different regions of Brazil and to verify if the prevailing mechanism of phosphine resistance in these populations involves reduced respiration rates. Sixteen populations of T. castaneum, 15 of R. dominica, 27 of S. zeamais and eight of O. surinamensis were collected from 36 locations over seven Brazilian states. Each population was tested for resistance to phosphine, based on the response of adults to discriminating concentrations, according to FAO standard method. For each insect species, the production of carbon dioxide of the most resistant and of the most susceptible populations was inversely related to their phosphine resistance. The screening tests identified possible phosphine resistant populations. R. dominica and O. surinamensis were less susceptible to phosphine than the other two species. The populations with lower respiration rate showed a lower mortality at discriminating concentration, possibly related to a phosphine resistance mechanism. Phosphine resistance occurs in stored-product insects, in different regions of Brazil, and the resistance mechanism involves reduced respiration rate.

Dezesseis populações de T. castaneum, 15 de R. dominica, 27 de S. zeamais e oito de O. surinamensis foram coletadas em 36 locais de sete estados brasileiros. Cada população foi testada quanto à resistência à fosfina, com base na resposta dos adultos à concentração discriminante, de acordo com o método padrão da FAO. Para cada espécie de insetos, as produções de dióxido de carbono da população mais resistente e a da mais suscetível foram inversamente relacionadas à resistência à fosfina. Os testes de detecção identificaram possíveis populações resistentes à fosfina. R. dominica e O. surinamensis foram menos suscetíveis à fosfina do que as outras duas espécies. As populações com menor taxa respiratória apresentaram menor mortalidade à concentração discriminante, o que está possivelmente relacionado ao mecanismo de resistência à fosfina. A resistência à fosfina ocorre em insetos de produtos armazenados, em diferentes regiões do Brasil, e o mecanismo de resistência envolve a redução da taxa respiratória.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraCNPq, FAPEMIGPimentel, Marco Aurélio GuerraFaroni, Lêda Rita D'AntoninoBatista, Maurílio DuarteSilva, Felipe Humberto da2009-01-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/706Pesquisa Agropecuaria Brasileira; v.43, n.12, dez. 2008; 1671-1676Pesquisa Agropecuária Brasileira; v.43, n.12, dez. 2008; 1671-16761678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/706/5573info:eu-repo/semantics/openAccess2012-06-17T11:45:36Zoai:ojs.seer.sct.embrapa.br:article/706Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2012-06-17T11:45:36Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
