Abstract

Chagas disease (also known as American trypanosomiasis) is a zoonosis caused by the flagellate protozoa trypanosomiasis, and the transmission of this disease depends on the blood-sucking insects belonging to Triatominae, Reduviidae, Hemiptera. This subfamily currently contains 154 species, which are widely distributed in various countries around the world. Triatominae species with different living habits and tolerance levels have different distribution ranges, and correct taxonomy can construct the global distribution range of different species, so that targeted measures can be taken to control Chagas disease to the greatest extent. Traditional taxonomic identification mainly relies on morphological observation, but for some species with great similarity in morphological characteristics, the dependence on morphological identification alone often leads to some errors, and in this case, genetic methods with higher accuracy are needed for confirmation. Genetic methods include cytogenetics and molecular genetics, and with the advantages of convenience, low costs, and accuracy, cytogenetics has become the most commonly used method for the taxonomic identification of Triatominae species.

Key words： Chagas disease; Triatominae; Cytogenetics
