Summary: During the summers of 2017-2019, there was a significant increase in Jamestown Canyon virus-associated disease cases in Wisconsin, with 60 human cases reported compared to 28 in the previous five years. The study found that Aedes provocans mosquitoes were the main vector species involved in the transmission of the virus.

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 investigates the infection response of Anopheles mosquitoes to Mayaro virus (MAYV) through transcriptomic and small RNA responses. A total of 487 unique transcripts were regulated, 78 putative novel miRNAs were identified, and an siRNA response targeting the MAYV genome was observed. Gene ontology analysis showed proteases regulated at 2 and 7 days post infection, while pathways related to autophagy and apoptosis were repressed at 14 days post infection.

Summary: This study identified several essential proteins for eggshell formation in Aedes aegypti and characterized their roles through molecular and biochemical approaches. These proteins, along with additional secreted eggshell enzymes, provide potential targets for future mosquito control strategies. Further research is needed to fully understand the mechanisms by which these proteins regulate eggshell formation and melanization.

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 investigated the use of nitrogen in the irradiation of adult Aedes albopictus and Ae. aegypti. The results showed that nitrogen treatment improved the longevity of irradiated males but slightly reduced their flight ability. Nitrogen treatment was found to be a reliable method for adult mosquito immobilization.

Summary: This review explores the correlations between temperature and dengue epidemics, including the distribution and development of Aedes mosquitoes, the structure of DENV, and the vector competence of Aedes mosquitoes. Additionally, it discusses the immune and metabolic mechanism through which temperature affects the vector competence of Aedes mosquitoes to transmit DENV.

Summary: Mosquitoes are important vectors for arboviruses, and insect-specific viruses (ISV) are also found in mosquitoes. This study investigated the infection and dissemination of the ASALV virus in Ae. aegypti mosquitoes through different routes. The virus replicated in the mosquitoes and disseminated to various tissues, with a preference for the brain. Horizontal transmission was observed, but vertical transmission was not observed. Understanding ISV infection and transmission dynamics in mosquitoes can potentially be used for arbovirus control strategies in the future.

Summary: The microbiota in mosquitoes, which is strongly influenced by the environment, plays a vital role in their behavior and vector competence. In this study, the microbiome profiles of adult female Anopheles sinensis mosquitoes from hyperendemic and hypoendemic malaria areas in Republic of Korea were compared. The analysis revealed significant differences in the alpha and beta diversity among different epidemiology groups. The most abundant bacterial phylum was Proteobacteria, with Staphylococcus, Erwinia, Serratia, and Pantoea being the dominant species in the microbiome of hyperendemic mosquitoes. Interestingly, a distinct microbiome profile dominated by Pseudomonas synxantha was identified in the hypoendemic area, suggesting a potential correlation between microbiome profiles and malaria incidence.

Summary: Palm Creek virus can interfere with mosquito-borne flavivirus replication in Culex mosquitoes, but does not have an effect on the transmission of Zika and chikungunya viruses in Aedes mosquitoes. Additionally, the interference mechanism is unlikely to be through RNA interference.

Summary: The study aimed to determine the sources and volume of tire imports in Iran and map the points of entry for entomological surveillance. The results showed that about one-third of Iran's annual tire requirements were imported from 15 countries, most of which were endemic to Aedes aegypti and Ae. albopictus. The majority of tire imports were made through southern ports and the main depot sites were located in four provinces, with special importance given to the border region with Pakistan.

Summary: The rapid increase in incidence and prevalence of dengue virus serotype 2 (DENV-2) in recent decades has necessitated a better understanding of the selective pressures driving genetic and phenotypic changes in this virus. In this study, DENV-2 was horizontally transmitted between suckling mice and Aedes aegypti mosquitoes to simulate virus transfer between human hosts and mosquito vectors. Three cycles of alternating transmission and three passages of virus population were performed, with viral titers and infectivity to mosquitoes tested. The genome of the viruses was also sequenced. Results showed similar viral titers and no significant difference in mosquito infection rates among the three passages. This in vivo model can be used to explore virus evolution and genetic variance in alternating transmission.

Summary: The study isolated 36 fungal strains from water samples collected in the state of Amazonas, Brazil, belonging to 23 different genera of fungi. Out of these, extracts from 8 fungal strains showed strong larvicidal activity against Aedes aegypti larvae, with some extracts killing over 90% of larvae within 72 hours, indicating potential for use in combating Aedes aegypti.

Summary: During pregnancy, women infected with ZIKV may have higher viral loads but show similar levels of inflammatory markers compared to nonpregnant individuals. The presence of ZIKV in pregnancy favors a regulatory profile with a systemic anti-inflammatory response, characterized by high levels of specific cytokines that are essential for antiviral response and have been correlated with congenital malformations.

Summary: The SARS-CoV-2 Lambda variant is prevalent in Latin America. Antibodies generated by CoronaVac and BNT162b2 were analyzed for their neutralizing capacity against SARS-CoV-2 Lambda in plasma samples from healthcare workers and patients in Chile. The study found that BNT162b2 elicits higher neutralizing antibody titres compared to CoronaVac. The study also identified mutations in the Lambda variant's spike protein that may contribute to immune escape.

Summary: Urbanisation alters mosquito distribution and community composition, potentially increasing the risk of vector-borne diseases due to habitat disturbance. This study analysed the presence of larvae and eco-physicochemical characteristics of water bodies in different urban and periurban areas of Villahermosa City, Tabasco, Mexico. A total of 67,528 larvae were collected, with 1366 identified species and 15 observed species. Although Culex spp. were dominant, Anopheles albimanus was the only species present in all habitats. Eco-physicochemical parameters showed variability among breeding sites, but weak correlations were found with species presence. Habitat disturbance may lead to eco-physicochemical variations and alter mosquito community composition, increasing the risk of vector-borne diseases in Villahermosa.
