INTRODUCTION: Besides mosquito species adapted to urban environments (Culex quinquefasciatusAedes aegypti and Aedes albopictus), only 15 species of Anopheles had been recorded in the State of Pernambuco.
METHODS: Human-landing mosquitoes were collected in Dois Irmãos Park, in Recife.
RESULTS: The first report for the state of Haemagogus janthinomys, an important vector of yellow fever virus, and 14 other species, including Trichoprosopon lampropus, a first reported for Brazil.
CONCLUSIONS: The mosquito fauna in the area is diversified and has potential medical and veterinary importance.

The mosquito fauna of the north-eastern Brazilian state of Pernambuco has been poorly studied. In fact, besides several reports confirming Culex quinquefasciatusAedes aegypti and Aedes albopictus, other species from the state have rarely been reported.

Pernambuco is situated in a tropical region, has a diversified climate and vegetation and knowledge of its mosquito fauna is very important. Besides studies concerning mosquitoes related to filariasis and dengue, very frequent diseases in several cities, data on other mosquitoes in the state is very scarce. Dirofilariasis was shown to occur in Recife1 and malaria transmission has occurred in the past. Although the state is currently outside the distribution of the sylvan cycle of yellow fever2, many cities are highly infested by Aedes aegypti, with many cases of dengue.

Collections were developed in a reservation (Dois Irmãos Park), in Recife, State of Pernambuco, Brazil. The park (http://www.parquedoisirmaos.pe.gov.br/; headquarter: 8º00’32.7″S 34º56’42.5″W, ca. 40m a.s.l.) was described previously3. Briefly, it includes two lagoons, surrounded by secondary Atlantic forest; it is very humid, mostly in winter, with diversified vegetation, including bromeliads and non-native bamboos. There is a zoo in the reservation and besides visitors to this zoo, many people from the densely populated neighborhood enter the forest.

Plastic suction tubes and collection boxes were used for mosquitoes landing on collectors, from 8am to 1pm, from July 27 2009 to November 28 2009. Mosquitoes were identified by keys4-6, checking original and complementary descriptions of each species. Genera were abbreviated as proposed by Reinert7.

The first reports for the State of Pernambuco of the following collected species, with the number of female specimens between parentheses: Coquillettidia hermanoi (17), Cq shannoni (9), Haemagogus janthinomys (5), Limatus durhamii (=Limatus durhami) (8), Mansonia wilsoni (3), Ochlerotatus hastatus/oligopistus/serratus (1), Oc scapularis (8), Sabethes tarsopus (1), Trichoprosopon lampropus (4), Wyeomyia arthrostigma (1), Wy coenonus/tarsata (1), Wy medioalbipes (5), Wy moerbista/cesari (1), Wy negrensis (1), Wy serratoria (1). This is the firstly report of Tr lampropus for Brazil.

At least 15 species not previously reported in Pernambuco were added to the known mosquito fauna of this state, which included, besides the urban species cited above, 15 of AnophelesAn albitarsis, An argyritarsis, An aquasalis (Plasmodium-infected), An bellator, An braziliensis, An cruziiAn darlingi, An eiseni, An fluminensis, An intermedius, An lutzi, An parvus, An peryassui, An strodei and An triannulatus.

Haemagogus janthinomys is an important vector of sylvan yellow feverand Mayaro virus8 and more thorough studies should be developed in Recife. Since it is still difficult to differentiate it from Hg capricornii9 and Hg leucocelaenus was recently reported in Natal10, Haemagogus mosquitoes from the north-east region of Brazil need to be carefully studied. Maraú (14º06’57″S 38º59’37″W)11 and Caravelas (17º42’48″S 39º59’55″W)9, both in the State of Bahia, are the most northern localities where Hg. janthinomys had previously been reported in Atlantic forest area.

Ochlerotatus scapularis has been incriminated as vector of Dirofilaria immitis in southeastern Brazil12. This mosquito has also been artificially infected by Rocio13 and yellow fever14 viruses and naturally infected by yellow fever virus in an outbreak in the State of Bahia15.

Females of mosquitoes of some Wyeomyia species (see above) and of Oc serratus and similar species occasionally still cannot be differentiated. Future collections mostly using light traps, in order to capture males, and examining breeding places, to capture immature forms, need to be developed for a more complete and secure identification.

The presence of Hg janthinomys and so many species of sylvan mosquitoes in an area where animals of several species (exotic and local) are present and many people circulate may induce the transmission of pathogens.

Ochlerotatus scapularis had been reported from the United States (Texas) to North Argentina, Sa tarsopus from Mexico to Peru and French Guiana, and in Brazil, it had been reported in the States of Amapá, Bahia, Rio de Janeiro and São Paulo. Tr lampropus, is first reported here for Brazil, had previously been reported only from Colombia. Wy negrensis had been reported only from Brazil and Wy arthrostigma, Wy serratoria and Wy medioalbipes from Brazil and other countries.

The high number of new reports of mosquito species for the State of Pernambuco, one of them new for Brazil, emphasizes the need to develop studies in forested areas in this huge country. The finding of a diversified Phlebotomine sandfly fauna exists in this reservation3, some of them potential vectors of Leishmania, including several species previously reported only in the Amazon region, reinforces the need of studies on the insect fauna in the area.
