Improving the population genetics toolbox for the study of the African malaria vector Anopheles nili: microsatellite mapping to chromosomes

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. Image: Mapping of a microsatellite on An. nili chromosomes.

A malaria transmission-directed model of mosquito life cycle and ecology

Philip A Eckhoff Malaria Journal 2011, 10:303 (17 October 2011)

This paper presents a new mathematical model describing the mosquito life-cycle and ecology. The model is fairly detailed and comprehensive, and similar in its intent and scope to the Depinay model.

Comparative analyses reveal discrepancies among results of commonly used methods for Anopheles gambiae molecular form identification

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.

Habitat suitability and ecological niche profile of major malaria vectors in Cameroon

Diego Ayala, Carlo Costantini, Kenji Ose, Guy C Kamdem, Christophe Antonio-Nkondjio, Jean-Pierre Agbor, Parfait Awono-Ambene, Didier Fontenille, Frédéric Simard Malaria Journal 2009, 8:307 (23 December 2009)

Ecological niche and species distribution modelling should help improve malaria vector control interventions by targeting places and times where the impact on vector populations and disease transmission can be optimized.

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.

Inversion 2La is associated with enhanced desiccation resistance in Anopheles gambiae

Emilie M Gray, Kyle AC Rocca, Carlo Costantini, Nora J Besansky Malaria Journal 2009, 8:215 (21 September 2009)

This paper presents a very focused analysis of adult mosquito characteristics relevant to dessication resistance. The major finding is that phenotypic characteristics of the adult female mosquitoes show an inversion-correlated resistance to dessication phenotype shortly after emergence.

2La chromosomal inversion enhances thermal tolerance of Anopheles gambiae larvae

Kyle AC Rocca, Emilie M Gray, Carlo Costantini, Nora J Besansky Malaria Journal 2009, 8:147 (2 July 2009)

The increased thermo-tolerance observed in 2La larvae following heat hardening suggests higher responsiveness of the inverted karyotype. By responding more drastically to the heat shock, 2La larvae are better equipped to resist the potentially lethal temperatures that occur in arid habitats.
