Estudo preliminar da preferência alimentar de Nyssomyia neivai (Pinto) e Nyssomyia whitmani (Antunes & Coutinho) (Diptera: Psychodidae) em área rural do Paraná

Abstract

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.

Leishmania (Viannia) braziliensis is the main species causing cutaneous leishmaniasis in the Federal District of Brazil

“…The high frequency of these species corroborates the findings of other endemic regions of Brazil (2). The high frequency of L. (V.) braziliensis coincides with the frequent finding of L. whitmani, a sand fly that can transmit this parasite to humans and domestic mammals (12,13). In contrast, the low frequency of L. (L).…”

Leishmania in synanthropic rodents (Rattus rattus): new evidence for the urbanization of Leishmania (Leishmania) amazonensis

“…In other words, the presence of animal species different from rats was a protection factor against leishmaniosis in rats (OR= 0.01273 to 0.8341). A study on Nyssomyia neivai species broadly found in Paraná State (MEMBRIVE et al, 2004;DIAS-SVERSUTTI et al, 2007;SILVA et al, 2008;CERINO et al, 2009;CRUZ et al, 2013;MELO et al, 2013), performed in Ribeira Valley São Paulo State, examined 988 engorged females, and no rat blood was detected in the phlebotomines (MARASSÁ et al, 2013). According to Dias-Sversutti et al (2007), N. neivai and N. whitmani are opportunists and probably adjust their feeding habits based on the availability of hosts.…”

Description of the female of Evandromyia rupicola (Martins, Godoy & Silva) with a review of the rupicola series (Diptera: Psychodidae: Phlebotominae)

“…Spermatheca width less than twice that of the individual sperm duct, this being as long as the common duct (Fig 12) ……………….……………............…… E. rupicola Width of spermatheca at least three times that of the individual duct, this being shorter than the common duct (Fig 19) So far, we have information that the rupicola series is restricted to Brazil and is limited to the Atlantic forest domain. Evandromyia correalimai is the species with the widest known distribution, including interior areas of the Southeastern (Forattini et al 1976, Galati et al 2010 and Southern regions (Martins et al 1970, 1978, Gomes & Galati 1977, Aguiar et al 1989, Dias et al 1997, Silva & Grunewald 1999, Luz et al 2000, Massafera et al 2005, Dias-Sversutti et al 2007, Silva et al 2008. Evandromyia rupicola is restricted to the Southeastern region, in the mountainous region of eastern Minas Gerais state (Mayrink et al 1979), Rio de Janeiro state (Martins et al 1962, 1978, Aguiar et al 1985, Afonso et al 2007 and in the coastal area of São Paulo state (Condino 2007).…”
