Project description:General information_new_RNA The whole transcriptome of four Aedes aegypti lines has been studied: - IR13, an isofemale line from Ile Royale, French Guiana, showing a weak resistance to deltamethrin - IR03, another isofemale line from Ile Royale, French Guiana, showing a strong resistance to deltamethrin, -IR0Free, a derivative of IR03 free from the kdr1034 mutation, still showing a strong resistance to deltamethrin, - Bora-Bora, a laboratory strain sensitive to deltamethrin. Illumina RNAseq data was obtained from 4 pools of 25 individuals for each line

Project description:Investigation of whole genome gene expression level changes of testes in the meiotic drive system in aedes aegypti during spermatogenesis compared to non drive strain. The meiotic drive system in Aedes aegypti causes the female determining chromosome to fragment during spermatogenesis. A six chip study using total RNA from three separately extracted non driving strain testes of Aedes aegypti and three separately extracted meiotic drive strain testes of Aedes aegypti.

Project description:Insecticide resistance is a worldwide threat for vector control around the world, and Aedes aegypti , the main vector of several arboviruses, is a particular concern. To better understand the mechanisms of resistance, four isofemale strains originally from French Guiana were isolated and analysed using combined approaches. The activity of detoxification enzymes involved in insecticide resistance was assayed, and mutations located at positions 1016 and 1534 of the sodium voltage-gated channel gene, which have been associated with pyrethroid resistance in Aedes aegypti populations in Latin America, were monitored. Resistance to other insecticide families (organophosphates and carbamates) was evaluated. A large-scale proteomic analysis was performed to identify proteins involved in insecticide resistance. Our results revealed a metabolic resistance and resistance associated with a mutation of the sodium voltage-gated channel gene at position 1016. Metabolic resistance was mediated through an increase of esterase activity in most strains but also through the shifts in the abundance of several cytochrome P450 (CYP450s). Overall, resistance to deltamethrin was linked in the isofemale strains to resistance to other class of insecticides, suggesting that cross- and multiple resistance occur through selection of mechanisms of metabolic resistance. These results give some insights into resistance to deltamethrin and into multiple resistance phenomena in populations of Ae. aegypti
