Large-scale use of mosquito larval source management for malaria control in Africa: a cost analysis Eve Worrall, Ulrike Fillinger Malaria Journal 2011, 10:338 (8 November 2011) Despite its enormous historical successes, mosquito larval source management (LSM) remains a largely forgotten and often dismissed intervention for malaria control in Africa, in large part because of the perceived cost of such interventions. The paper shows that costs for LSM compare favourably with costs for IRS and LLINs, especially in areas with moderate and focal malaria transmission where mosquito larval habitats are accessible and well defined.

Spatial targeted vector control in the highlands of Burundi and its impact on malaria transmission Natacha Protopopoff, Wim Van Bortel, Tanguy Marcotty, Michel Van Herp, Peter Maes, Dismas Baza, Umberto D'Alessandro, Marc Coosemans Malaria Journal 2007, 6:158 (3 December 2007) A targeted and focalized strategy combining IRS and LLTNs to reduce malaria transmission in valleys. This approach would reduce the cost of the programme and enhance sustainability. While the intervention was highly successful in the treated areas, the impact failed to spread to the hilltops.
