Resumo: | Oviposition and feeding preferences of the bollworm, Heliothis zea (Boddie) on cotton, Gossypium hirsutum L., cultivar 'Tamcot CAMD-E', were studied. A highly significant number of eggs on terminal and leaves indicated clearly that bollworm moths exibit a high degree of preference for egg placement on these parts. Feeding sites for bollworm larvae were quite variable among instars and plant parts, except for white flowers and red flowers which were the most preferred feeding sites for all larval instars. Terminals and leaves were the second most damaged plant parts by the first instars. Large boll preferences increased from fourth to sixth instars, with a peak of damage in the fifth instar. It was concluded that egg placement may vary among plant parts. Feeding preference sites varied from instar to instar within the various cotton plant parts. Consequently, caution should be taken in common scoring practices. |

Os terminais e as folhas do algodoeiro foram as duas partes preferidas para oviposição. Houve uma variação muito grande entre o estádio da larva e a parte da planta preferida para a alimentação, embora as flores novas e velhas fossem as preferidas para alimentação por todos os estádios larvais. Os terminais e as folhas constituíram a segunda parte da planta em grau de dano por larvas de primeiro instar. Maçãs grandes tiveram a preferência de larvas do quarto ao sexto estádios com um maior dano causado por larvas do quinto estádio. Pode-se concluir que a preferência para oviposição variou entre as diferentes partes da planta. Preferência para alimentação variou entre instares dentro das diferentes partes da planta. Deste modo, cuidados devem ser tomados nas amostragem de campo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraBraga Sobrinho, RaimundoYoung, Jerry HarrisYoung, Linda Johnson1991-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3534Pesquisa Agropecuaria Brasileira; v.26, n.11/12, nov./dez. 1991; 1851-1857Pesquisa Agropecuária Brasileira; v.26, n.11/12, nov./dez. 1991; 1851-18571678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3534/867info:eu-repo/semantics/openAccess2010-08-17T18:39:01Zoai:ojs.seer.sct.embrapa.br:article/3534Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-08-17T18:39:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
