| [mass production of romanomermis iyengari (nematoda: mermithidae) applied to anopheline breeding sites in boa vista (roraima), brazil]. | in order to begin mass producing the nematode romanomermis iyengari welch, a bioprocessing plant was designed and set up on the grounds of universidad federal in the state of roraima, brazil, after reaching an agreement with the state's health department. the objective of this paper was to establish the basic process for mass breeding the parasite in order to apply it to anopheline breeding sites. cultures were obtained at a rate of 68 during every seven-day cycle, making for a total of 272 cult ... | 2000 | 10808748 |
| 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 |
| affinity and diversity indices for anopheline immature forms. | as for the entire amazon region, malaria continues to be a major health public problem in roraima that presented an annual parasitic index of 85.4 in 2005, the highest in brazil. information on anopheline breeding sites is an essential component in malaria control strategies. aiming to contribute to the limited knowledge on anopheline immature forms in roraima, collections and breeding site observations were performed in 10 breeding sites around the capital city boa vista. collections were carri ... | 2007 | 18026638 |
| the importance of anopheles albitarsis e and an. darlingi in human malaria transmission in boa vista, state of roraima, brazil. | in several districts of boa vista, state of roraima, brazil we found anopheles (nyssorhynchus) albitarsis e to be the primary vector of human malaria parasites, and during 2001-2002 it was significantly more abundant than an. darlingi (p < 0.001). other species sampled were an. (nys.) braziliensis, an. (ano.) peryassui, an. (nys.) nuneztovari, an. (nys.) oswaldoi s.l., and an. (nys.) triannulatus. as determined by the elisa technique an. darlingi had a higher overall infection rate (2.1%) compar ... | 2006 | 16830709 |
