New Records of Triatomine: Triatoma rubida1 and T. sinaloensis1 at Sonora, Northwestern Mexico

Abstract

To update a list of arthropod group-species, including triatomines, in the State of Sonora, northwestern Mexico, entomological surveys were done during the spring of 2022 in conserved areas of the state. Triatomines Triatoma rubida (Uhler) and T. sinaloensis Ryckman (Hemiptera: Reduviidae) were found living in nests of woodrats, Neotoma sp., and California roadrunners, Geococcyx californianus (Lesson). Because T. rubida is one of the main vectors of Chagas disease in North America, and T. sinaloensis has been found naturally infected with Trypanosoma cruzi Chagas, surveillance of the species should be essential for Chagas disease control programs in northwestern Mexico.
