Malaria risk and endemicity is often associated with the nature of human habitation and living environment. The disappearance of malaria from regions where it had been endemic for centuries, such as coastal areas of southern England, has been attributed, at least in part, to improvement in the quality of housing. Moreover, indigenous malaria transmission ceased throughout England without the necessity to eliminate the vector mosquitoes.
Malaria-causing parasites are transmitted from humans to mosquitoes when developmentally arrested gametocytes are taken up by a female Anopheles during a bloodmeal. The changes in environment from human to mosquito activate gametogenesis, including a drop in temperature, a rise in pH and a mosquito-derived molecule, xanthurenic acid. Signalling receptors have not been identified in malaria parasites but mounting evidence indicates that cGMP homeostasis is key to sensing extracellular cues in gametocytes.
The impact of large dams on malaria has received widespread attention. However, understanding how dam topography and transmission endemicity influence malaria incidences is limited.
The aim of this study was to evaluate the larvicidal activity of a genetically engineered cyanobacterium, Anabaena PCC 7120#11, against five African Anopheles species in laboratory bioassays.

Turkey is located in the middle of Asia, Africa and Europe, close to Caucasia, Balkans and Middle East in subtropical climate zone.
Biovision, in support of the implementation of the Global Alliance for Alternatives to DDT, has organised a series of posters to present alternatives to DDT. The posters on innovative products, methods and alternative strategies for malaria vector control have been displayed alongside the Fifth Meeting of the Conference of the Parties to the Stockholm Convention.
