Abstract

SANTOS, Demilson Rodrigues dos et al. Observing diurnal habits of Nyssomyia whitmani (Diptera: Psychodidae) in the urban area of Maringá, Paraná, Brazil. Epidemiol. Serv. Saúde [online]. 2009, vol.18, n.3, pp.227-236. ISSN 1679-4974.  http://dx.doi.org/10.5123/S1679-49742009000300005.

The diurnal habits of six species of phlebotomine in the urban area of Maringá, in the State of Paraná, Brazil are described in this study. The specimen were collected during yellow fever surveillance activities, in a forest and at its fringe using an insect net and a glass tube containing cotton and chloroform for a total twelve hours monthly from June 2000 to May 2001, as well as on residences and henhouse walls on December 18th, 2003. A total of 323 females were captured in the forest and anthropic environments, where Ny. whitmani accounted for 93.7 % and 92.0%, respectively. In the forest, the frequency of phlebotomines was higher from 6 a.m. to 12 a.m. (97.0%), with a peak between 9 a.m. and 11 a.m. (59,1%), mainly in collections with the presence of non-human primates (September 2000 and May 2001). In the anthropic environment, the highest frequency was from 6 a.m. to 8 a.m. (96.0%). Considering the role of Ny. whitmani as an important vector of cutaneous leishmaniasis (CL) in Brazil and the overwhelming predominance of that sandfly in the urban area of Maringá, where a cutaneous leishmaniasis (CL) outbreak has been reported, new cases of CL may occur and the Leishmania spp may be transmitted even during the day.

Keywords : urbanization; leishmaniasis; vectors.
