Short report
Sheila B Ogoma, Hassan Ngonyani, Emmanuel T Simfukwe, Anthony Mseka, Jason Moore, Gerry F Killeen Parasites & Vectors 2012, 5:54 (20 March 2012) The protective efficacy of transfluthrin-treated hessian strips, made from sisal fibers, in terms of reduced exposure to mosquito bites whilst outdoors, was measured. The treated strip reduced mosquito attack by >90% for 6 months. Image: Measuring the protective efficacy of transfluthrin-treated hessian strip against outdoor biting mosquitoes.

Research
Target product profiles for protecting against outdoor malaria transmission Gerry F Killeen, Sarah J Moore Malaria Journal 2012, 11:17 (11 January 2012) The authors extend a previously published mathematical model to investigate the combined use of outdoor and indoor malaria vector control tools. These tools consist of a contact toxicant and a spatial repellent.

Impact of insecticide-treated bed nets on malaria transmission indices on the south coast of Kenya Francis M Mutuku, Charles H King, Peter Mungai, Charles Mbogo, Joseph Mwangangi, Eric M Muchiri, Edward D Walker, Uriel Kitron Malaria Journal 2011, 10:356 (13 December 2011) Entomological indices indicate a much reduced human biting rate and a diminishing role of An. gambiae s.s. in malaria transmission following high bed net coverage. While increasing bed net coverage beyond the current levels may not significantly reduce the transmission potential of An. arabiensis, it is anticipated that increasing or at least sustaining high bed net coverage will result in a diminished role for An. funestus in malaria transmission.

Larval source management for malaria control in Africa: myths and reality Ulrike Fillinger, Steven W Lindsay Malaria Journal 2011, 10:353 (13 December 2011) The manuscript presents a compelling argument for the potential value of larval control of malaria vectors in Africa.

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.

While several previous studies had reported the vectors as mainly endophilic, it appears that the mixed molecular forms of the population may have changed to only M-form during the period of the intervention.
