Hemiptera: Heteroptera in the different environments present in the Municipal Reserve “Laguna Don Tomas: La Malvina”, Santa Rosa, Argentina

Abstract :

The action of man upon nature generally reduces the richness of species in ecosystems, causing loss of biodiversity. The urban reserve “Las Malvinas” (36º 18' 18.31 '' S and 64º 18' 49.02 '' W), is located near a hyperopic lagoon, surrounded by lacustrine vegetation, eucalyptus forest, dunes, grasslands and caldenal. The reserve was divided into three sampling zones, in each zone 6 random samples were taken, the method used to capture the heteroptera was the Beating sheet. A components analysis was performed to find a projection showing the relationship between different sites and species. A total of 613 specimens were obtained, corresponding to 10 families (Coreidae, Largidae, Lygaeidae, Miridae, Nabidae, Pentatomidae, Reduviidae, Rhopalidae, Rhyparochromidae and Thaumastocoridae), the Grassland and Eucalyptus environments presented the highest percentages of species, 47% and 44% respectively, while the Caldenal environment presented only 9% of the total species. The PCA respect to the first two components explained 93.40% of the variability. The data obtained in this work constitute the first records of Heteroptera in the Urban Nature Reserve: La Malvina, Argentina.
