[Preliminary study on feeding preference of Nyssomyia neivai (Pinto) and Nyssomyia whitmani (Antunes & Coutinho) (Diptera: Psychodidae) in a rural area of the State of Paraná, South Brazil].

Due to the importance of sandflies in the American cutaneous leishmaniasis epidemiology, we investigated the feeding preference of sandflies related to domestic animals common in domiciliary environments in endemic rural areas, where this disease occurs. The sandflies were collected with Falcão light traps, installed in cages, each one containing one domestic animal kind (pig, dog, rabbit or chicken), in Recanto Marista, in Doutor Camargo municipality. Forty five collections were made, totaling 135h of collections per trap. A total of 2,854 sandflies of the following species were collected: Brumptomyia brumpti (Larousse), Evandromyia correalimai (Martins, Coutinho & Luz), Evandromyia cortelezzii (Brèthes), Expapillata firmatoi (Barreto, Martins & Pellegrino), Micropygomyia ferreirana (Barreto, Martins & Pellegrino), Migonemyia migonei (França), Nyssomyia neivai (Pinto), Nyssomyia whitmani (Antunes & Coutinho), Pintomyia fischeri (Pinto), Pintomyia monticola (Costa Lima), Pintomyia pessoai (Coutinho & Barreto), Psathyromyia lanei (Barreto & Coutinho) and Psathyromyia shannoni (Dyar). The dominant species was N. neivai. N. neivai and N. whitmani did not show any feeding preference towards the animals used as bait. It was concluded that N. neivai and N. whitmani are opportunist and, probably, the females adjust their feeding habits to the availability of hosts, suggesting their feeding eclecticism in the anthropic environments.
