TEODORO, Ueslei; KUHL, João B.; SANTOS, Demilson R. dos  and  SANTOS, Élcio S. dos. Impact of environmental changes on sand fly ecology in southern Brazil . Cad. Saúde Pública [online]. 1999, vol.15, n.4, pp. 901-906. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X1999000400025.

Tree felling around a chicken coop and periodic insecticide spraying at the Palmital farm in the county of Terra Boa in southern Brazil impacted the ecology of sand fly species. The most prevalent species (51.6%) before clearing the trees and insecticide spraying was Lutzomyia migonei (França, 1920), and it is now Lutzomyia (Nyssomyia) whitmani (Antunes & Coutinho, 1939) (89.8%). There was a highly significant difference between the proportions of L. whitmani reported by this paper (89.8%) and another publication before the tree felling and insecticide spraying (32.6%).
