| analysis of its2 dna sequences from brazilian anopheles darlingi (diptera: culicidae). | specimens of anopheles darlingi root, the major vector of malaria in brazil, were collected from several states in brazil: sao paulo (dourado), bahia (itabela), rondônia (porto velho), roraima (boa vista), and acre (plácido de castro). sequence divergence in the 2nd internal transcribed spacer (its2) was examined. the its2 sequences of mosquitoes captured in the amazon region (porto velho, boa vista and plácido de castro) and in the northeast of brazil (itabela) were almost identical; however, a ... | 1999 | 10534960 |
| man biting rate seasonal variation of malaria vectors in roraima, brazil. | malaria control has been directed towards regional actions where more detailed knowledge of local determinants of transmission is of primary importance. this is a short report on range distribution and biting indices for anopheles darlingi and an. albitarsis during the dry and rainy season that follows river level variation in a savanna/alluvial forest malaria system area in the northern amazon basin. distribution range and adult biting indices were at their highest during the rainy season for b ... | 2007 | 17568934 |
| distribution summaries of malaria vectors in the northern brazilian amazon. | knowledge of vector distribution is important for the design of effective local malaria control programs. here we apply ecological niche modeling to analyze and predict the distributions of malaria vectors based on entomological collection points in the state of roraima in the northern brazilian amazon basin. anopheline collections were conducted from 1999 to 2003 at 76 localities, all with active malaria transmission. a total of 13 anopheline species was identified from 17,074 adult females col ... | 2007 | 18260503 |
