Sandfly Fauna And Behavior (Diptera: Psychodidae) In Municipalities Of The Mesoregion North Pioneer Of Parana, Brazil

The occurrence of cutaneous leishmaniasis (CL) in the municipalities of Jaboti, Japira, Pinhalao, and Tomazina in the North Pioneer of the State of Parana, where this disease is endemic, prompted the investigation of sandfly fauna, their population changes throughout the year, and their behavior in and around human accommodation. In these municipalities, the collection of sandflies was conducted using Falcao traps from 7 pm to 6 am once a month. 32,994 sandflies, 18,442 males and 14,552 females, were collected and represented by the species Brumptomyia brumpti, Brumptomyia cunhai, Evandromyia correalimai, Evandromyia cortelezzii, Expapillata firmatoi, Micropygomyia ferreirana, Migonemyia migonei, Nyssomyia neivai, Nyssomyia whitmani, Pintomyia fischeri, Pintomyia monticola, Pintomyia pessoai, and Psathyromyia bigeniculata. Ny. neivai (SISA = 0.9808) predominated in Japira (46.9%), Pinhalao (53.1%), and Tomazina (38.9%), while Ny. whitmani (SISA = 0.9423) predominated in Jaboti (53.8%). Most sandflies were captured in domestic animal shelters, with a peak in September. The high number of sandflies collected in domestic animal shelters, species richness, and presence of species involved in the epidemiology of CL reveal the need for permanent entomological surveillance in the municipalities mentioned. The use of phlebotomine control measures in these municipalities should be considered in conjunction with the anthropogenic actions that have resulted in changes to sandfly fauna and behavior.
