CONTRERAS RIVERO, Gilberto; NAVARRETE SALGADO, Norma Angélica; FERNANDEZ, Guillermo Elías  e  ROJAS BUSTAMANTE, Margarita Laura. Aspectos ecológicos de los Corixidae (Hemiptera, Heteroptera) en el estanque piscícola "GL" de Soyaniquilpan de Juárez, Estado de México. Hidrobiológica [online]. 2001, vol.11, n.1, pp.53-60. ISSN 0188-8897.

In this work, the species of the Corixidae family in the piscicole pond "GL" in Soyaniquilpan de Juárez (State of Mexico) are analized, as well as their density and the relationship with some environmental parameters recording during October of 1995 to August of 1996. Four species were recorded: Trichocorixella mexicana Hungerford, 1942; Graptocorixa sp. Hungerford, 1930; Krizousacorixa femorata Guerín-Meneville, 1847 and Corisella edulis Champion, 1901. T. mexicana was more abundant in November. K. femorata was more abundant in January and less abundant in May. C. edullis only was recorded in October with low density. The Principal Components Analysis, signal that the parameters with the most influence in the system, as well as on the density of the Corixidae family, were the hardness, the alkalinity and the pH.
