Ashley Peery, Maria V Sharakhova, Christophe Antonio-Nkondjio, Cyrille Ndo, Mylene Weill, Frederic Simard, Igor V Sharakhov Parasites & Vectors 2011, 4:202 (19 October 2011) We developed a chromosome map of microsatellite markers for Anopheles nili, a major malaria vector in the humid savannas and forested areas of sub-Saharan Africa. This map allows genome-wide inferences about the population structure of An. nili.

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.

Seasonal distribution of Anopheles funestus chromosomal forms from Burkina Faso Wamdaogo M Guelbeogo, N'Fale Sagnon, Olga Grushko, Malgaouende A Yameogo, Daniela Boccolini, Nora J Besansky, Carlo Costantini Malaria Journal 2009, 8:239 (26 October 2009) The relative abundance of different chromosomal forms reflects different larval ecologies that are linked to varying climatic conditions. Further analysis of the bionomics of the vectors is of relevance for vector control.
