Resumo: Triploidy due to meiotic nondisjunction is a rare event in Diptera. Cytogenetic analyses performed in a population of fruit flies Anastrepha obliqua from the state of Rio Grande do Norte, northeast of Brazil, identified the occurrence of one triployd individual. This is the first case of triploidy described in the Anastrepha genus.  Samples of A. obliqua larvae were obtained from Spondias purpurea (red mombin) fruits.  A. obliqua presents a diploid value of 2n=12 observed in 29 specimens, whereas a triploid individual presented 3n=18. The triploid specimen showed three AgNOR sites and a variation from one to three nucleoli in interphase nuclei, in contrast to the two sites in the diploids. In  Anastrepha, natural triploidy is proving to be a rare event and apparently holds no evolutionary significance to the species A. obliqua.Keywords: Tephritidae; insect cytogenetics; polyploidy; northeastern Brazil.

Triploidia decorrente da não disjunção meiótica são eventos incomuns em Diptera. Análises citogenéticas desenvolvidas em uma população da mosca-das-frutas Anastrepha obliqua, oriunda do Estado do Rio Grande do Norte, nordeste do Brasil identificaram a ocorrência de um indivíduo triploide. Este é o primeiro caso descrito de triploidia no gênero Anastrepha. Larvas de A. obliqua foram obtidas a partir de frutos de Spondias purpurea (ciriguela). A. obliqua apresenta um valor diploide 2n=12, presente em 29 espécimes, enquanto o indivíduo triploide apresentou 3n=18. O espécime apresenta três sítios Ag-RONs e uma variação de um a três nucléolos em núcleos interfásicos, ao contrário dos dois sítios nos diploides. No gênero Anastrepha, triploidia natural demonstra ser um evento raro e aparentemente sem significado evolutivo para a espécie A. obliqua.Palavras-chave: Tephritidae, citogenética de insetos, poliploidia, nordeste do Brasil Universidade Federal do AmapáCNPqCAPESFINEPCunha, Inês de Araújo MouraMolina, Wagner FrancoMacedo, Francisco Pepino de2014-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/63810.18561/2179-5746/biotaamazonia.v4n2p169-171Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 4, n. 2 (2014); 169-1712179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/638/v4n2p169-171.pdfhttps://periodicos.unifap.br/index.php/biota/article/downloadSuppFile/638/66https://periodicos.unifap.br/index.php/biota/article/downloadSuppFile/638/67Nordeste do BrasilContemporâneapopulação naturalDireitos autorais 2014 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2016-04-13T17:58:54Zoai:ojs.pkp.sfu.ca:article/638Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2016-04-13T17:58:54Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
