Cross-sectional entomological surveys were carried out during the 2006 dry and rainy seasons in Lagdo, Cameroon to measure the impact of rice cultivation on malaria transmission and to monitor vector susceptibility to insecticides. Adult anopheline mosquitoes were captured on human volunteers and by pyrethrum spray collections. A total of 4740 mosquitoes was collected during the study. Anophele...

Human malaria is known to be transmitted strictly by anopheline mosquitoes. Culicine mosquitoes such as Aedes spp. and Culex spp. are important vectors of other human pathogens including viruses and filarial worms, but have never been observed to transmit mammalian malarias. Culicines do transmit avian malarias and, interestingly, allow partial development of mammalian-infectious Plasmodium par...

We investigated the seasonality of Anopheles mosquitoes, including its species composition, density, parity, and population densities of mosquitoes infected with the parasite in Ganghwa-do (Island), a vivax malaria endemic area in the Republic of Korea. Mosquitoes were collected periodically with a dry-ice-tent trap and a blacklight trap during the mosquito season (April-October) in 2008. Anoph...

The introduction of genes that impair Plasmodium development into mosquito populations is a strategy being considered for malaria control. The effect of the transgene on mosquito fitness is a crucial parameter influencing the success of this approach. We have previously shown that anopheline mosquitoes expressing the SM1 peptide in the midgut lumen are impaired for transmission of Plasmodium be...

To date, no polymerase chain reaction diagnostic technique exists to directly identify mammalian blood meals from mosquitoes by sized DNA fragments following agarose gel electrophoresis. We have developed a vertebrate-specific multiplexed primer set based on mitochondrial cytochrome b to identify the mammalian blood hosts of field-collected mosquitoes. Although designed for the study of African...

During the past 7 years, 24 species of Nearctic mosquitoes have had extensions to their known distribution in the form of 32 new state and province records in the United States and Canada. They are included in this report along with relevant references. Additionally, 3 new United States country records have been established, 3 species have had name changes, a new species of Anopheles and siblin...

Morphological analysis of anopheline mosquitoes from Kasane, Botswana, revealed a new species, Anopheles seretsei, that is closely related to Anopheles azevedoi and Anopheles listeri. A description of the type locality and biological characteristics of An. seretsei is given. Comparisons are made with An. listeri and An. azevedoi. The banding patterns of the giant polytene chromosomes of An. ser...
