Summary: Aedes aegypti is the main vector for dengue and chikungunya viruses, but they exhibit different genetic responses to the two viruses. Genetic variation in the mosquito contributes to the viral loads of both viruses, but the genetic mechanisms are distinct. The identification of genes involved in virus control provides potential targets for genetic modification to reduce the transmission of these diseases by mosquitoes.

Summary: This study explored the relationship between seasonal climate variability and dengue fever (DF) in Brazil using temperature-based models. The results showed that areas with higher mosquito survival probabilities and shorter extrinsic incubation periods (EIPs) were more likely to have DF case reports, but with significant intra-annual variability. The study also extrapolated the findings to the Americas, mapping the seasonal change in the range of areas suitable for dengue virus transmission and the population living in those areas using climate data from the past decade (2010-2019).

Summary: This study characterized the microbial communities associated with Aedes aegypti and Aedes albopictus larvae and adults in Thailand. There were significant changes in the representation of many bacterial taxa between the larval and adult stages. Aedes aegypti had a higher number of bacterial genera than Aedes albopictus, except for the genus Wolbachia, which was more abundant in male Aedes albopictus. The findings suggest transstadial transmission and provide important insights into mosquito microbial diversity for future disease control programs.

Summary: There are various methods to collect and assess the abundance of dengue vector mosquitoes, but the lack of long-term sampling methods may result in variability and lack of statistical significance in the results. There is no correlation between the collection methods and the presence of dengue virus in mosquitoes or the incidence of dengue, and the efficacy of a given method is inconsistent across different locations.

Summary: The study compared Aedes mosquito catch rates between passive gravitraps and active fan-traps in six urban areas of Kaohsiung City in 2019. Fan-traps consistently showed higher capture rates compared to gravitraps, with values more closely aligned with reported dengue fever cases and weekly fluctuations in temperature and rainfall. This supports the use of fan-traps for Aedes mosquito surveillance and control within broader vector management strategies, potentially aiding in early identification and prevention of disease outbreaks.

Summary: Controlling malaria involves using insecticides to kill mosquitoes, but increasing levels of insecticide resistance (IR) pose a threat to recent successes in malaria control. To mitigate this problem, insecticide resistance management (IRM) strategies are employed. Field trials of IRM strategies are costly and time-consuming, so mathematical modeling is often used to evaluate alternative options. Previous models assumed a simple genetic basis for IR, but in natural populations, IR is often a complex polygenic trait. A quantitative genetics model was developed to simulate IR as a polygenic trait and evaluate different IRM strategies. The results showed that deploying two insecticides in a full-dose mixture formulation extended the strategy lifespan, regardless of the level of cross resistance or starting level of resistance. This study highlights the importance of insecticide coverage, cross resistance, heritability, and fitness costs in selecting an appropriate IRM strategy.

Summary: Ae. aegypti is a common mosquito vector of arboviruses in urbanized areas of the tropics and subtropics, but control of this species is difficult and costly. The literature on adult Ae. aegypti biology and behavior near human homes is lacking in important details, making it unreliable for developing control interventions. Basic information sources are poor and outdated, while commonly accepted facts lack evidence. Topics such as sugar feeding, resting preferences, and blood feeding require further research to identify vulnerabilities for control efforts in different contexts.

Summary: In recent decades, several zoonotic arboviruses transmitted by mosquitoes have caused large-scale epidemics in humans. Although it is believed that these arboviruses adapt to domestic mosquito vectors for transmission, this is not usually the direct cause of their initial emergence. Secondary adaptation to domestic mosquitoes can amplify transmission, but it is more likely a consequence rather than a cause of arbovirus emergence. Recognizing that emerging arboviruses are generally preadapted for domestic mosquito vectors can improve preparedness for future arbovirus emergence events.

Summary: This study investigated the transmission of dengue virus from mildly ill individuals to mosquitoes. The researchers found that transmission risk was highest on the second day of illness, rather than on the first day as previously reported. The level of viremia and the duration of the extrinsic incubation period in mosquitoes were identified as important factors influencing transmission probability. Understanding the variation in infectiousness and contributing factors is crucial for disease surveillance and prevention strategies.
