Article Synopsis
- * Weekly collections using ovitraps were conducted in residential and uninhabited areas, analyzing the number of positive traps and egg counts while considering seasonal and climatic factors impacting mosquito activity.
- * Results indicated significant differences in egg presence across study sites, with a seasonal pattern of abundance peaking in February and declining in winter, influenced by temperature and rainfall variations, and showing higher productivity in residential areas.
The control of mosquito populations using insecticides is increasingly threatened by the spread of resistance mechanisms. Dieldrin resistance, conferred by point mutations in the Rdl gene encoding the γ-aminobutyric acid receptor, has been reported at high prevalence in mosquito populations in response to selective pressures. In this study, we monitored spatio-temporal dynamics of the resistance-conferring RdlR allele in Aedes (Stegomyia) albopictus (Skuse, 1895) and Culex (Culex) quinquefasciatus (Say, 1823) populations from Reunion Island.

Although Aedes albopictus can transmit ZIKV experimentally and was suspected to be a ZIKV vector in Central Africa, the potential of this species to sustain virus transmission was yet to be uncovered until the end of 2019, when several autochthonous transmissions of the virus vectored by Ae. albopictus occurred in France.

The sterile insect technique (SIT) is rapidly evolving as an additional tool for mosquito control, offering an efficient and more environment-friendly alternative to the use of insecticides. Following the devastating chikungunya outbreak, which affected 38% of the population on Reunion Island (a French overseas territory in the southwest of the Indian Ocean), there has been strong interest and political will to develop effective alternatives to the existing vector control strategies.

- * This study focused on the 'Tiger mosquito' (Aedes albopictus) in Reunion Island, using both empirical and process-based models with weather data to evaluate mosquito populations.
- * Findings showed that mosquito dynamics were influenced by rainfall and temperature, leading to the creation of a user-friendly mapping tool for public health services to monitor and manage mosquito populations effectively.
