Fauna of aquatic insects in Kashan

Aquatic insects are able to transit the pathogens and disturb human beings. So, this study was performed to determine the type and distribution of insects in Kashan during 2001-2002. This is a descriptive study, in which 2222 larva and mature insects were collected from pools and stream habitats. After transporting to laboratory, they were diagnosed using morphologic diagnostic clues. The frequency of different types of insects was as following: Diptera 55%, Trichoptera 24%, Heteroptera 8%, Ephemeroptera 7%, Coleoptera 3% and Odonata 3%. Considering the role of insects in transmitting pathogens and their disturbance for human beings, it is recommended further specific studies using molecular methods.
