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: This study found that blood glucose enhances DENV replication in mosquitoes, leading to increased virus transmission. The activation of AKT and TOR signaling pathways plays a crucial role in facilitating this process. This insight may contribute to understanding the relationship between dengue fever and diabetes mellitus and could potentially offer new targets for antiviral therapies.

Summary: C-type lectins can target DENV, and transgenic mosquitoes expressing human CLEC18A show potential in enhancing Toll immune pathway responses, reducing viral titers, and altering midgut microbiome composition, leading to inhibition of DENV.

Summary: In this study, we found that prohemocytes were the major type of hemocyte infected by DENV in both Ae. aegypti and Ae. albopictus. The infection rate of prohemocytes in Ae. albopictus was lower than that in Ae. aegypti, which may explain why systemic DENV infection in Ae. albopictus is less efficient than in Ae. aegypti and why Ae. albopictus is less correlated to dengue fever outbreaks.

Summary: The study reveals the negative impact of juvenile hormone on the expression of immunity-related genes in female mosquitoes. It further demonstrates the important role of juvenile hormone in regulating mosquito immune responses. The findings suggest that juvenile hormone suppresses antimicrobial peptide gene expression through its receptor Met, while PGRP-LC activates this gene, indicating dual regulation by both the juvenile hormone and IMD signaling pathways.

Summary: Aedes aegypti, the main mosquito vector for dengue and other arboviral infectious diseases, has developed high levels of pyrethroid resistance in populations collected from Vietnam and Cambodia. This resistance could pose a serious threat to the control of dengue fever and other Aedes-borne infectious diseases.

Summary: The study analyzed the mechanism by which insect-specific viruses affect mosquito vector competence to transmit dengue virus to humans. Two mosquito-specific viruses, Phasi Charoen-like virus (PCLV) and Humaita Tubiacanga virus (HTV), were found to be the most abundant in Aedes aegypti worldwide. The presence of HTV and PCLV increased the ability of mosquitoes to transmit dengue virus and Zika virus to a vertebrate host.

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.

Summary: This study demonstrates that the Malpighian tubules (MT) in mosquitoes can directly respond to Toll pathway activation and regulate gene silencing through RNA interference. The transcriptional response of the MT significantly overlaps with the changes in the proteome of the hemolymph, suggesting a potential role of the MT in mosquito humoral immunity.

Summary: This study built a mathematical model based on meteorological and mosquito vector monitoring data in Guangdong Province, China, to explore the effects of temperature and rainfall on the population dynamics of Aedes albopictus. The study found that temperature and rainfall had different effects on the developmental stages of mosquitoes in different periods and locations. It also identified rainfall as being more important than temperature distribution and evenness for mosquito population development, with peak summer rainfall being the best indicator.

Summary: Dengue is becoming an increasing global threat in rapidly growing urban areas. This study analyzes nine years of dengue case data in Medellin, Colombia and finds that changes in accessibility and usage of public transit are correlated with changes in the spread and magnitude of localized outbreaks. Locations closer to and with greater utilization of public transit have higher dengue incidence, with a stronger effect observed in lower socioeconomic status areas. These results emphasize the importance of public health services in conjunction with urban growth.

Summary: This study describes a semi-field system for studying the ability of wAlbB-Tw mosquitoes to suppress local mosquito populations. The results show that wAlbB-Tw has a significant potential for use in vector control strategies aimed at Ae. aegypti population suppression. Open field release trials are now necessary to confirm the feasibility of wAlbB-Tw mediated suppression in natural environments.

Summary: Reducing the density of mosquito vectors and preventing the spread of mosquito-borne diseases is crucial. We developed a smart mosquito trap system that utilizes computer vision technology and deep learning networks to identify live mosquitoes in real-time. The unique mechanical design successfully captures specific mosquitoes without damaging their important features. Equipped with environmental sensors, this system also detects CO2 concentration, temperature, and humidity. With high accuracy rates, this smart trap can effectively control mosquito-borne diseases and predict possible outbreaks.

Summary: Dengue fever has become a serious global public health problem, and mosquito density reduction is crucial in controlling and preventing mosquito-borne diseases. This study used unmanned ground vehicle systems to observe vector mosquito ecology in urban ditches, finding viable breeding sources in about 20.7% of inspected ditches. Insecticide application based on UGV detection yielded good control results, suggesting that this approach could effectively detect and control mosquito breeding sources in urban ditches.

Summary: In this study, researchers found that C-type lectin 5A (CLEC5A) plays a crucial role in testicular damage caused by Zika virus infection. CLEC5A enables leukocytes to infiltrate past the blood-testis barrier and induce damage to testicular and epididymal tissues, and it is associated with inflammatory responses. Therefore, CLEC5A may be a potential therapeutic target for the prevention of male reproductive organ injuries in Zika virus patients.
