Update on resistance status of Anopheles gambiae s.s. to conventional insecticides at a previous WHOPES field site, "Yaokoffikro", 6 years after the political crisis in Côte d'Ivoire

Alphonsine A Koffi, Ludovic Alou, Maurice A Adja, Moussa Koné, Fabrice Chandre, Raphael N'Guessan Parasites & Vectors 2012, 5:68 (2 April 2012)

The results presented here show that insecticide resistance in the S form of An. gambiae s.s. is multifactorial at this locality and includes, in addition to target site mutations, enhanced metabolic mechanism components never identified before. At least four resistance mechanisms were found: high frequency of the L1014F kdr, ace-1R and increased activity of NSE and GSTs.

Combining indoor residual spraying with chlorfenapyr and long-lasting insecticidal bed nets for improved control of pyrethroid-resistant Anopheles gambiae: an experimental hut trial in Benin

Corine Ngufor, Raphael N'Guessan, Pelagie Boko, Abibatou Odjo, Estelle Vigninou, Alex Asidi, Martin Akogbeto, Mark Rowland Malaria Journal 2011, 10:343 (16 November 2011)

A very relevant paper given the prevailing malaria vector control landscape where there are emerging reports of pyrethroid insecticide resistance among malaria vectors across Africa at a rate never experienced before.

Dynamics of insecticide resistance in malaria vectors in Benin: first evidence of the presence of L1014S kdr mutation in Anopheles gambiae from West Africa

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.

Managing insecticide resistance in malaria vectors by combining carbamate-treated plastic wall sheeting and pyrethroid-treated bed nets

Armel Djènontin, Joseph Chabi, Thierry Baldet, Seth Irish, Cédric Pennetier, Jean-Marc Hougard, Vincent Corbel, Martin Akogbéto, Fabrice Chandre Malaria Journal 2009, 8:233 (20 October 2009)

This paper addresses a topic of major importance in the control not only of malaria vectors but other disease vectors. Resistance is becoming more widespread and the disease control community looks for ways to combat resistance, either through development of new technologies or novel ways in which to deliver insecticides.
