Project description:Transcription profiles of three field collections of Anopheles gambiae M molecular form (i.e. Anopheles coluzzii) from West Africa were compared to investigate their phenotypic differences in insecticide resistance. The susceptibility status for the individual samples was unknown but known for their source populations via phenotypic assays performed concurrently with the sample collections.
Project description:We use RNA-Seq to investigate gene expression differences in response to saltwater exposure by the larval stages of the obligate freshwater mosquito Anopheles coluzzii (formerly An. gambiae "M" form), and the euryhaline An. merus.
Project description:Transcription profiles of a field collection of Anopheles gambiae M molecular form (i.e. Anopheles coluzzii) from a population from Cote d'Ivoire (West Africa) were compared to two laboratory strains and to a wild caught field strain (all carbamate insecticide susceptible) to investigate their differences in insecticide resistance. Both carbamate-exposed and carbamate-unexposed Cote d'Ivoire samples were compared to each susceptible strain, and also directly to one another (i.e. exposed vs. unexposed).
Project description:We use RNA-Seq to investigate gene expression differences in response to saltwater exposure by the larval stages of the obligate freshwater mosquito Anopheles coluzzii (formerly An. gambiae "M" form), and the euryhaline An. merus. After rearing in freshwater, both young and old larval instars of each species were briefly (6 h) exposed to either saltwater (SW) or freshwater (FW) conditions to test the impact of salinity on mRNA levels.
Project description:Field resistant Anopheles coluzzii were compared to the lab susceptible Anopheles coluzzii N'Gousso. The samples were collected in 2014 in Burkina Faso and show resistance to pyrethroid insecticides.
Project description:We use RNA-Seq to explore the reaction norm of gene expression of larval Anopheles coluzzii and An. merus to a gradient of salinity.
Project description:Gene expression was determined for Male accessory gland and testes in different members of the Anopheles gambiae complex, including An. gambiae (Savannah, MRA-762), An. coluzzii (Mopti) [2], An. arabiensis [3], An. merus [4] and An. quadriannalatus [5. All the mosquito stocks were obtained from the Malaria Research and Reference Reagent Resource Center (MR4) in Atlanta (https://www.beiresources.org/Catalog/BEIVectors/MRA-762.aspx). References: 1.
