Aquatic/semi-aquatic   Heteroptera (Hemiptera) Diversity of Kızıl Lake (Tomarza: Kayseri) and Some Physicochemical Conditions

ABSTRACT: This study was conducted to identify the aquatic and semi-aquatic heteroptera fauna of Kızıl Lake, a natural lake in Türkiye, and to provide information about the habitats of these aquatic insects by determining their current water quality. For this aim, samplings in water and sediment were done in the August of 2025  . Some physicochemical parameters (pH, temperature, dissolved oxygen, salinity, and electrical conductivity) of water were       measured simultaneously with collection of insect samples.  A total of 10 aquatic/semi-aquatic Heteropteran species were identified in the research area. The species Gerris lacustris (Linnaeus, 1758) and Sigara nigrolineata (Fieber, 1848) were recorded first time in Kayseri Province. Also, according the measured physicochemical parameters, water quality level was evaluated.
