Hemipteros acuáticos en dos estanques piscícolas del Estado de México

the species of aquatic hemiptera in the piscicole ponds gl and jc of soyaniquilpan de juárez, estado de méxico are analyzed during october of 1995 to august 1996. were recorded environmental parameters in the two systems as well as the abundance and diversity of hemiptera. the gl pond presented eight species: buenoa uhleri truxal, 1953; b. margaritacea bueno, 1908; trichocorixella mexicana hungerford, 1927; notonecta shooterii uhler, 1849; krizousacorixa femorata guerín, 1857; graptocorixa abdominalis (say), 1832; n. undulata say, 1832 and corisella edulis (champion), 1901 and seven in jc pond: t. mexicana, b. margaritacea, g. abdominalis, n. shooterii, k. femorata, b. uhleri and c. edulis.the diversity was major in gl pond and minor in jc pond. the pca remarks to the conductivity, depth, oxygen and ph in gl pond (84.3 % of variability), and jc pond the conductivity, transparence and ph were the most important (83.5 %). is concluded that the enviromental variations registered in two systems are not considerables, but their influence on the diversity and abundance are notably as well as the environmental heterogeneity of the two systems.
