| description and bionomics of anopheles (cellia) ovengensis (diptera: culicidae), a new malaria vector species of the anopheles nili group from south cameroon. | mosquito species of the anopheles nili group (diptera: culicidae) transmit malaria to humans along rivers in africa. to date, the an. nili group includes the species anopheles nili s.s. and its pale-winged variant known as the "congo form," anopheles somalicus and anopheles carnevalei. larval and adult mosquito collections in the forest region of campo, in southern cameroon, uncovered an additional morphological variant provisionally called "oveng form" that was subsequently found to be genetica ... | 2004 | 15311444 |
| complexity of the malaria vectorial system in cameroon: contribution of secondary vectors to malaria transmission. | malaria transmission in africa is a dynamic and complex system that is so far superficially understood. further knowledge is required to improve control of the disease. in the present report, we highlight the contribution of the so-called "secondary" malaria vectors to the overall parasite transmission intensity in several sites across cameroon, through a retrospective analysis of surveys from the organisation de coordination pour la lutte contre les endémies en afrique centrale database. in tot ... | 2006 | 17162956 |
| a pre-intervention study of malaria vector abundance in rio muni, equatorial guinea: their role in malaria transmission and the incidence of insecticide resistance alleles. | following the success of the malaria control intervention on the island of bioko, malaria control by the use of indoor residual spraying (irs) and long-lasting insecticide-treated nets (llitn) was extended to rio muni, on the mainland part of equatorial guinea. this manuscript reports on the malaria vectors present and the incidence of insecticide resistant alleles prior to the onset of the programme. | 2008 | 18823554 |
| distribution and larval habitat characterization of anopheles moucheti, anopheles nili, and other malaria vectors in river networks of southern cameroon. | despite their importance as malaria vectors, little is known of the bionomic of anopheles nili and anopheles moucheti. larval collections from 24 sites situated along the dense hydrographic network of south cameroon were examined to assess key ecological factors associated with these mosquitoes distribution in river networks. morphological identification of the iii and iv instar larvae by the use of microscopy revealed that 47.6% of the larvae belong to an. nili and 22.6% to an. moucheti. five v ... | 2009 | 19682965 |
| cytogenetic analysis of anopheles ovengensis revealed high structural divergence of chromosomes in the anopheles nili group. | cytogenetic analysis is an informative classical approach to understanding the relationships among members in a group of closely related species of mosquitoes. anopheles ovengensis is a recently discovered species of the anopheles nili group and is one of the important malaria vectors in the african equatorial forest. this study characterized polytene chromosomes of an. ovengensis and compared them with polytene chromosomes of an. nili. using fluorescent in situ hybridization and chromosome band ... | 2013 | 23523820 |
