Resumo: The objective of this work was to determine the biological and morphological parameters of Dysdercus maurus fed with cotton (Gossypium hirsutum) seeds with a high or low oil content, as well as to identify genotypes to be used in breeding programs as sources of resistance to this stink bug. The development, survival, and reproduction of the cotton stainer bug were determined in a completely randomized experimental design. The treatments consisted of the insect nymphs being feed with cotton seeds of the CNPA 2001-5581 (high oil content) or CNPA 2001-5087 (low content) genetic line. Survival, weight, and morphological parameters of the bug were determined. The survival of second- and third-instar nymphs and of the total nymph stage of D. maurus was lower with cotton seeds with a low oil content. The body length and head width of D. maurus adults were greater, but pronotum length and width were smaller and the females heavier with cotton seeds with a high oil content. Low-oil cotton genotypes can reduce populations of the stainer bug.

O desenvolvimento, a sobrevivência e a reprodução do percevejo manchador de algodão foram determinados em delineamento experimental inteiramente casualizado. Os tratamentos consistiram de ninfas do inseto alimentadas com sementes de algodão da linhagem genética CNPA 2001-5581 (alto teor de óleo) ou CNPA 2001-5087 (baixo teor). Foram determinados a sobrevivência, o peso e os parâmetros morfológicos do percevejo. A sobrevivência das ninfas de segundo e terceiro ínstars e do estágio total de ninfas de D. maurus foi menor com sementes de algodão com baixo teor de óleo. O comprimento do corpo e a largura da cabeça dos adultos de D. maurus foram maiores, mas o comprimento e a largura do pronoto menores e as fêmeas mais pesadas com sementes de algodão com alto teor de óleo. Genótipos de algodão com baixo teor de óleo podem reduzir as populações do percevejo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmpresa Brasileira de Pesquisa AgropecuáriaEmpresa Brasileira de Pesquisa AgropecuáriaSilva, Carlos Alberto Domingues daGaldino, Josivaldo da SilvaCarvalho, Thiele da SilvaZanuncio, José Cola2021-02-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/26885Pesquisa Agropecuaria Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e02052Pesquisa Agropecuária Brasileira; V.56, Jan./Dec., 2021: Publicação contínua em volume anual; e020521678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/26885/14844Direitos autorais 2021 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2022-05-18T18:27:35Zoai:ojs.seer.sct.embrapa.br:article/26885Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2022-05-18T18:27:35Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
