In this article, pyrethroid metabolite measurements were reported to be specific gravity-corrected. However, the statistical analyses were completed with uncorrected pyrethroid metabolite measurements. The results using specific gravity-corrected metabolite measurements are largely consistent with the uncorrected analyses.

Pyrethroid-impregnated bed nets have driven considerable reductions in malaria-associated morbidity and mortality in Africa since the beginning of the century1. The intense selection pressure exerted by bed nets has precipitated widespread and escalating resistance to pyrethroids in African Anopheles populations, threatening to reverse the gains that been made by malaria control2. Here we show that expression of a sensory appendage protein (SAP2), which is enriched in the legs, confers pyrethroid resistance to Anopheles gambiae.

Adult susceptibility tests were performed using World Health Organization (WHO) test tube kits for F1 progenies of field-collected An. gambiae s.s., An. arabiensis, and An. funestus s.s., and laboratory colonies of An. gambiae s.s. and An. arabiensis.

An experimental hut study to quantify the effect of DDT and airborne pyrethroids on entomological parameters of malaria transmission

This study highlights that airborne pyrethroids and DDT affect a range of anopheline mosquito behaviours that are important parameters in malaria transmission, namely deterrence, irritancy/excito-repellency and blood-feeding inhibition.

Is the bednet era coming to an end?

June 22, 2012 - 12:47 -- Bart G.J. Knols

Whenever I teach on the history of malaria, I talk about the different time periods when certain ideas were fashionable and implemented, and then disappeared, and sometimes came back much later.

Take the 'chloroquine era'. Discovered by Bayer scientists in the early 1930s and saved millions of lives around the globe, followed by resistance popping up in SE Asia and Colombia in the late 1950s. Resistance spreading to Africa in the late 1970s, and its use now largely reduced. End of the 'chloroquine era'.

Waking up in the face of resistance?

Sometimes you come across articles that blow your mind. You read them and feel your heartbeat increasing. Each sentence you finish makes you wonder more what is going on here. What the politics are, who's really behind it, and what the goal of it is....
