Innocent Djègbè, Olayidé Boussari, Aboubakar Sidick, Thibaud Martin, Hilary Ranson, Fabrice Chandre, Martin Akogbéto, Vincent Corbel Malaria Journal 2011, 10:261 (12 September 2011) Pyrethroid and DDT resistance is widespread in malaria vector in Benin and both metabolic and target site resistance are implicated. Resistance was not correlated with a change of malaria species and/or molecular forms. The L1014S kdr allele was first identified in wild population of An. gambiae s.s and An. arabiensis hence confirming the expansion of pyrethroid resistance alleles in Africa.

Federica Santolamazza, Beniamino Caputo, Maria Calzetta, José L Vicente, Emiliano Mancini, Vincenzo Petrarca, João Pinto, Alessandra della Torre Malaria Journal 2011, 10:215 (2 August 2011) The results reveal that the PCR and PCR-RFLP approaches most commonly utilized to identify A. gambiae M and S forms are not fully interchangeable, as usually assumed. There are operational suggestions on the choice of the most convenient method for large-scale M- and S-form identification.

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.

Raphael N'Guessan, Pelagie Boko, Abibathou Odjo, Joseph Chabi, Martin Akogbeto, Mark Rowland Malaria Journal 2010, 9:44 (8 February 2010) The study indicates that chlorpyrifos methyl outperformed DDT and lambdacyhalothrin. In IRS campaigns, it should provode improved levels of transmission control compared to conventional formulations of DDT or pyrethroids, always assuming that the product is available for such use.

Although the results of the paper do not provide overwhelming support for the deltamethrin and piperonyl butoxide combination bednet, it is an important negative result.

Wim Van Bortel, Vu Chinh, Dirk Berkvens, Niko Speybroeck, Ho Trung, Marc Coosemans Malaria Journal 2009, 8:248 (29 October 2009) This paper describes the results of experimental hut trials to investigate the efficacy of a variety of insecticide-treated nets. The local vector population is partially resistant to multiple pyrethroid insecticides and so the rational behind the study was to determine whether the nets were still effective against resistant mosquitoes.

Methodology
A new tent trap for sampling exophagic and endophagic members of the Anopheles gambiae complex Nicodemus J Govella, Prosper P Chaki, Yvonne Geissbuhler, Khadija Kannady, Fredros Okumu, J Derek Charlwood, Robert A Anderson, Gerry F Killeen Malaria Journal 2009, 8:157 (14 July 2009) There have been numerous malaria studies published, which mostly depend on human landing catch or CDC-LT collections, but only few studies have looked at alternative sampling tools, which are needed in resource-poor areas where even batteries are often not available. A tent trap requires only one human person sleeping in it, while all mosquito sampling tools to-date depend on human (volatiles), which vary significantly and hence, sampling is strongly dependent on the odour characteristics of the human host.

Insecticide resistance may jeopardize the success of such programmes.

The demonstration of a high frequency of kdr alleles in mosquito populations before the onset of a malaria control programme shows the importance of continuous entomological surveillance.

Sonia LR Casimiro, Janet Hemingway, Brian L Sharp, Michael Coleman Malaria Journal 2007, 6:142 (31 October 2007) The development of insecticide resistance is a potential threat to any insecticide-based malaria vector control programme. The re-introduction of DDT into Mozambique’s IRS programme in 2005 poses interesting questions. Is monitoring insecticide resistance feasible for a malaria control programme and what the impact of monitoring would this have on policy ?
