Resumo: The boll weevil (Anthonomus grandis Boheman) causes high levels of bud abscission in cotton plants due to feeding or oviposition punctures. It has been reported that abscission is mainly due to enzymes present in the insect's saliva, but mechanical damage could also contribute to square abscission. The objective of this paper was to undertake an analysis of the morphological damages caused by the insect in cotton squares using microscopy. Anthers and ovules are the main target of boll weevil feeding. The process initiates by perforation of young sepal and petal tissues and proceeds with subsequent alimentation on stamen and ovary leading to abscission of floral structures.

Embora a abscisão ocorra em virtude principalmente da ação de enzimas presentes na saliva do inseto, o dano mecânico também poderia contribuir para a queda dos frutos. O objetivo desse trabalho foi avaliar danos morfológicos causados pelo inseto nos botões florais com auxílio da microscopia. O principal alvo de alimentação do bicudo são as anteras e os óvulos. Esse processo, preferencialmente iniciado nas sépalas e pétalas mais novas, inclui a perfuração dos tecidos e posterior mastigação dos estames e ovário levando a abscisão da estrutura floral.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSantos, Roseane CavalcantiMarcellino, Lucília HelenaMonnerat, Rose GomesGander, Eugen Silvano2003-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6711Pesquisa Agropecuaria Brasileira; v.38, n.11, nov. 2003; 1351-1356Pesquisa Agropecuária Brasileira; v.38, n.11, nov. 2003; 1351-13561678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6711/3768info:eu-repo/semantics/openAccess2014-08-11T19:47:24Zoai:ojs.seer.sct.embrapa.br:article/6711Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:47:24Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
