Second WIN International Conference on “integrated approaches and innovative tools for combating insecticide resistance in vectors of arboviruses”, October 2018, Singapore

  • Authors: Corbel V, Durot C, Achee NL, Chandre F, Coulibaly MB, David JP, Devine GJ, Dusfour I, Fonseca DM, Griego J, Juntarajumnong W, Lenhart A, Kasai S, Martins AJ, Moyes C, Ng LC, Pinto J, Pompon JF, Müller P, Raghavendra K, Roiz D, Vatandoost H, Vontas J, Weetman D

The past 40 years have seen a dramatic emergence of epidemic arboviral diseases transmitted primarily by mosquitoes. The frequency and magnitude of the epidemics, especially those transmitted by urban Aedes species, have progressively increased over time, accelerating in the past 10 years. To reduce the burden and threat of vector-borne diseases, the World Health Organization (WHO) has […]

Aedes Mosquitoes and Aedes-Borne Arboviruses in Africa: Current and Future Threats

The Zika crisis drew attention to the long-overlooked problem of arboviruses transmitted by Aedes mosquitoes in Africa. Yellow fever, dengue, chikungunya and Zika are poorly controlled in Africa and often go unrecognized. However, to combat these diseases, both in Africa and worldwide, it is crucial that this situation changes. Here, we review available data on […]

Remarkable diversity of intron-1 of the para voltage-gated sodium channel gene in an Anopheles gambiae/Anopheles coluzzii hybrid zone

BACKGROUND: Genomic differentiation between Anopheles gambiae and Anopheles coluzzii–the major malaria vectors in sub-Saharan Africa–is localized into large “islands” toward the centromeres of chromosome-X and the two autosomes. Linkage disequilibrium between these genomic islands was first detected between species-specific polymorphisms within ribosomal DNA genes (IGS-rDNA) on the X-chromosome and a single variant at position 702 […]

Limited genomic divergence between intraspecific forms of Culex pipiens under different ecological pressures

Divergent selection can be a major driver of ecological speciation. In insects of medical importance, understanding the speciation process is both of academic interest and public health importance. In the West Nile virus vector Culex pipiens, intraspecific pipiens and molestus forms vary in ecological and physiological traits. Populations of each form appear to share recent common […]

Massive introgression drives species radiation at the range limit of Anopheles gambiae

  • Authors: Antao T, Bottà G, Caputo B, Clarkson CS, Dinis J, Donnelly MJ, Drury E, Gomes B, Kwiatkowski DP, Mancini E, Mead D, Miles A, Petrarca V, Pinto J, Pombi M, Rodrigues A, Sousa CA, Stalker J, Torre AD, Vicente JL, Weetman D

Impacts of introgressive hybridisation may range from genomic erosion and species collapse to rapid adaptation and speciation but opportunities to study these dynamics are rare. We investigated the extent, causes and consequences of a hybrid zone between Anopheles coluzzii and Anopheles gambiae in Guinea-Bissau, where high hybridisation rates appear to be stable at least since […]
