Malaria prevention in Africa is mainly through the use of long-lasting insecticide treated nets (LLINs). The objective of the study was to assess the effect of supplementing LLINs with either larviciding with Bacillus thuringiensis israelensis (Bti) or community education and mobilization (CEM), or with both interventions in the context of integrated vector management (IVM).
Despite historical and contemporary evidence of its effectiveness, larval source management with insecticides remains little used by most malaria control programs worldwide. Here we show that environmentally safe biological larvicides under field conditions can significantly reduce anopheline larval density in fish farming ponds that have became major larval habitats across the Amazon Basin.
Last week, WHO published a statement regarding the potential of larviciding for malaria control in Africa. This followed the circulation of a draft version of the statement in August 2011. That draft was sent to a limited group of people (how many I don't know) for comments (including myself). I attach the official version to this editorial.
