Resumo: The mealybugs Planococcus citri and Planococcus minor (Hemiptera: Pseudococcidae) have increased their importance in brazilian coffee and cause similar damage to plants. Our objective was to determine the characteristics related to the development of these species, testing the hypothesis that, despite of considered cryptic, they have different biological characteristics. Mealybugs crawlers were individually isolated inside Petri dishes containing coffee leaf discs on an agar layer. Its development was monitored until adult emergence when females were enclosed with a male. We evaluated fertility parameters and by means of a life table, we estimated the mean generation time (T), the reproduction net rate (Ro), the increasing net rate (Rm), the finite increasing rate (λ) and the time needed to double the number of individuals (TD). Generally, the reproductive and fertility parameters did not differ between both species. These results show that females of both species produce similar number of descendents rejecting the tested hypothesis.

Assim, objetivou-se determinar as características relacionadas ao desenvolvimento dessas espécies, testando-se a hipótese de que, embora consideradas crípticas, essas cochonilhas apresentem aspectos biológicos diferentes. Ninfas recém-eclodidas foram individualizadas em placas de Petri contendo discos foliares de cafeeiro dispostos sobre uma lâmina de ágar-água. O desenvolvimento dos insetos foi acompanhado até a emergência dos adultos, quando se procedeu à formação dos casais. Avaliaram-se as características reprodutivas e, por meio da tabela de vida, foram estimados: duração média de uma geração (T), taxa líquida de reprodução (Ro), taxa intrínseca de aumento (Rm), razão finita de aumento (λ) e tempo necessário para duplicar em número de indivíduos (TD). De uma maneira geral, as características reprodutivas, bem como aquelas avaliadas na tabela de vida de fertilidade, não diferiram entre as espécies. As fêmeas de ambas as espécies produziram número similar de descendentes, rejeitando-se a hipótese testada.Editora UFLA2016-05-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/ziphttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1048Coffee Science - ISSN 1984-3909; Vol. 11 No. 2 (2016); 204 - 210Coffee Science; Vol. 11 Núm. 2 (2016); 204 - 210Coffee Science; v. 11 n. 2 (2016); 204 - 2101984-3909reponame:Coffee Science (Online)instname:Universidade Federal de Lavras (UFLA)instacron:UFLAporhttps://coffeescience.ufla.br/index.php/Coffeescience/article/view/1048/pdf_1048https://coffeescience.ufla.br/index.php/Coffeescience/article/view/1048/1560Copyright (c) 2016 Coffee Science - ISSN 1984-3909https://creativecommons.org/info:eu-repo/semantics/openAccessCosta, Marlice BotelhoSouza, BrigidaPrado, ErnestoSanta-Cecília, Lenira Viana Costa2016-05-13T03:36:21Zoai:coffeescience.ufla.br:article/1048Revistahttps://coffeescience.ufla.br/index.php/CoffeesciencePUBhttps://coffeescience.ufla.br/index.php/Coffeescience/oaicoffeescience@dag.ufla.br||coffeescience@dag.ufla.br|| alvaro-cozadi@hotmail.com1984-39091809-6875opendoar:2024-05-21T19:53:55.723995Coffee Science (Online) - Universidade Federal de Lavras (UFLA)true
