Resumo: | It is known that Ecuador is a megadiverse country, favored by the ecosystems it has. It is to be expected that this is also reflected in the mite populations. In what refers to those present in the soil and litter, this group has different habits, among which are the regulation of soil conditions and their role as biological controllers of pests. The current study aimed at measuring this diversity, concentrating on the Mesostigmata order, in the three continental Ecuadorian regions: Amazon, Coast and Highland, in cultivated and non-cultivated environments, in soil substrate and litter, which in turn made it possible to make supplementary descriptions of species from Ecuador and others already described with little detail. For this, samples were taken in the wet season between 2018 and 2019. The mites were extracted using the modified Berlese-Tullgren method. First, a differentiation of the mite orders was made and later mesostigmatid mites were identified. In Chapter 2, the diversity and abundance of the mesostigmatid mites collected from the three regions are shown, relating to the environments where they were collected. In some cases, identification of species was possible. But in in most cases the mites were identified to morphospecies, within the 16 families identified. Chapter 3 refers specifically to selected species of the family Ologamasidae, including the description of a new species (Gamasiphis n. sp.) and supplementary descriptions of G. plenosetosus Karg and G. salvadori Castilho, Narita & Moraes, with new reports from Ecuador. |

É de se esperar que isso também se reflita nas populações de ácaros. No que se refere aos ácaros presentes no solo e no folhedo, esse grupo possui hábitos diversos, entre os quais se destacam a regulação das condições do solo e o controle biológico de pragas. O presente estudo teve como objetivo mensurar essa diversidade, concentrando-se na ordem Mesostigmata, nas três regiões continentais: Amazônia, Litoral e Serra, em ambientes cultivados e não cultivados; em substrato de solo e folhedo, o que por sua vez possibilitou fazer descrições complementares de espécies do Equador e outras já descritas com poucos detalhes. Para isso, as coletas foram realizadas no período chuvoso entre 2018 e 2019. Os ácaros foram extraídos pelo método de Berlese-Tullgren modificado. Primeiramente, foi feita uma diferenciação das ordens dos ácaros e, posteriormente, os ácaros mesostigmatídeos foram identificados. No Capítulo 2, são apresentadas as medidas de diversidade e abundância dos ácaros mesostigmatídeos identificados nas três regiões, relacionando os ambientes onde foram coletados. Em alguns casos, foi possível identificar as espécies, mas na maioria dos casos os gêneros foram identificados, e em cada um destes, as morfoespécies, dentro das 16 famílias identificadas. O Capítulo 3 trata especificamente de espécies selecionadas da família Ologamasidae, incluindo a descrição de uma nova espécie (Gamasiphis n. sp.) e descrições suplementares de G. plenosetosus Karg e G. salvadori Castilho, Narita & Moraes, com novos relatos para Equador.Biblioteca Digitais de Teses e Dissertações da USPMoraes, Gilberto José deMelo-Molina, Elsa Liliana 2022-02-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/11/11146/tde-10052022-153044/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2022-05-10T20:38:40Zoai:teses.usp.br:tde-10052022-153044Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212022-05-10T20:38:40Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
