Previous issue date: 2006-12-15 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / The species psaroniocompsa incrustata (Lutz, 1910) was studied in relation to its abundance in different and seasonal periods, the physico-chemical of the breending ground and the fauna predation added to the immature of the species. The study was developed during eight months, from April to July, 2005 (rainy season) and from October, 2005 to January, 2006 (drought season), in one natural breending ground situated in the Pium river, that is part of the hydrographical basin of the Pirangi river in Rio Grande do Norte. The immature of Simuliidae were collected manually in vegetal substrate. At the same place, it was made one sampling of the associated fauna using Suber collectors and the measurement of the environment variants. It was also made one analysis of the stomach content of possible enemies of the simul?deos, to observe the predation of the associated fauna. It was collected 7.713 samples, all from de species P. Incrustata, it was observed a bigger abundance in the drought season, and the entomologic fauna associated totalizing 20.1314 species, distributed in the kinds: Diptera, Ephemeroptera, Odonata, Trichoptera, e Hemiptera, with a bigger representativity of Dipteros. The analysis of the stomach content of the species from the families Libellulidae and Hydropsychidae showed the presence of the simul?deos in only 4% of the material analysed, therefore it was not confirmed the presence of one efficient biological control of the simul?deos in this breending ground / A esp?cie Psaroniocompsa incrustata (Lutz, 1910) foi estudada quanto a abund?ncia em per?odos sazonais diferentes, a f?sico-qu?mica do criadouro e a preda??o da fauna associada sobre os imaturos desta esp?cie. O estudo foi realizado durante oito meses, abril ? julho de 2005 (esta??o de chuvas) e outubro/2005 ? janeiro/2006 (esta??o de seca), em um criadouro natural localizado no rio Pium, pertencente a Bacia Hidrogr?fica do rio Pirangi, no Rio Grande do Norte. Os imaturos de Simuliidae foram coletados manualmente em substrato vegetal. Nesse mesmo local, foi realizada a amostragem da fauna associada utilizando-se coletor do tipo Surber, e as medi??es das vari?veis ambientais. Para observar a preda??o da fauna associada, foi realizada a an?lise do conte?do estomacal de poss?veis inimigos naturais dos simul?deos. A coleta dos imaturos resultou em 7.713 exemplares, todos da esp?cie P. incrustata, sendo a sua maior abund?ncia observada na estac?o de seca, e a entomofauna associada, totalizou 20.314 esp?cimes, distribu?dos nas Ordens: Diptera, Ephemeroptera, Odonata, Trichoptera e Hemiptera, com maior representatividade dos d?pteros. A an?lise do conte?do estomacal dos esp?cimes das fam?lias Libellulidae e Hydropsychidae revelou a presen?a de simul?deos em apenas 4% do material examinado, n?o sendo constatado a realiza??o de um eficiente controle biol?gico por parte destes, sobre os simul?deos, nesse criadouro
