Resumo: The objective of this work was to assess the boll weevil, Anthonomus grandis Boheman, 1843 (Coleoptera: Curculionidae) feeding preference for fruits of two cotton cultivars at different ages. The number of feeding holes was assessed in four laboratory experiments. Cotton bolls from cultivars IAC-20 and Reba P288, at the age of 2, 8 and 12 days were offered to the insects, confined in recipients, with (first experiment) and without (second experiment) possibilities of choice both age and cultivar; without possibilities of choice concerning cultivar and with possibilities of choice concerning age (third experiment); without possibility of choice concerning age and with possibility of choice concerning cultivar (fourth experiment). Boll weevil showed preference for the fruits of IAC-20 cultivar. Insect fed more frequently on fruits at the age of two days, with damage reduction of 23.53% and 78.43% on fruits at the age of 8 and 12 days, respectively.

Foram realizados quatro experimentos em laboratório, avaliando-se o número de orifícios de alimentação. Maçãs de 2, 8 e 12 dias de idade, das cultivares IAC-20 e Reba P288, foram oferecidas aos insetos, confinados em recipientes, com opção de escolha quanto à idade e cultivar (primeiro experimento), sem opção de escolha quanto à idade e cultivar (segundo experimento), sem opção de escolha quanto à cultivar e com opção quanto a idade (terceiro experimento) e sem opção quanto à idade e com opção de escolha quanto à cultivar (quarto experimento). Observou-se preferência por maçãs da cultivar IAC-20 com dois dias de idade, com uma redução de danos de 23,53% e 78,43%, respectivamente, aos oito e aos doze dias de idade.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBusoli, Antonio CarlosPereira, Francisco FernandesLopéz, Victor Adolfo GómezSoares, José JanduíMelo, Rachel de Souzade Almeida, Cleandro Alves2004-02-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6743Pesquisa Agropecuaria Brasileira; v.39, n.2, fev. 2004; 101-104Pesquisa Agropecuária Brasileira; v.39, n.2, fev. 2004; 101-1041678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6743/3799info:eu-repo/semantics/openAccess2014-07-02T17:13:59Zoai:ojs.seer.sct.embrapa.br:article/6743Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-07-02T17:13:59Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
