Summary: The study found that Aedes albopictus mosquitoes from southern-western China have lower loads of dengue virus, which may be related to the innate immunity of mosquitoes, Wolbachia strains, and their relative densities.

Summary: This study surveyed the mitogenomes of 149 Culicidae species and found that their gene composition and order are consistent with an ancestral insect. The phylogenetic analysis based on the DNA sequences supports the monophyly of certain subfamilies and tribes within Culicidae. Additionally, the study estimated the divergence times of mosquitoes, indicating that they diverged during the Early Jurassic and experienced radiation during the Cretaceous.

Summary: This study assessed Wolbachia prevalence and genetic diversity in different mosquito species from Cape Verde. The results showed high Wolbachia prevalence and diversity in species from the Cx.pipiens complex. Wolbachia was also detected in Cx.tigripes, which may provide an additional opportunity for biocontrol initiatives.

Summary: Symbiotic bacteria in Anopheles mosquitoes can alter host biology and the transmission of diseases. A study identified a symbiont called 'Ca. Tisiphia' in Anopheles plumbeus and investigated its genome and metabolic competence. This research provides valuable insights into the symbiotic relationships in Anopheles mosquitoes and their impact on host biology and disease transmission.

Summary: The genetic identity of Wolbachia endosymbiont in wild-caught Culex quinquefasciatus in Indonesia was determined for the first time, revealing a new discovery of group A Wolbachia. Phylogenetic analysis showed that the strains from Indonesia were genetically affiliated to supergroups A and B with high sequence similarity. Group-specific infections were detected, with group A having a lower genetic distance compared to other Wolbachia strains.

Summary: The prevalence and genetic character of Wolbachia endosymbionts in field-collected Aedes aegypti mosquitoes were examined for the first time in Taiwan. A total of 665 Ae. aegypti were screened for Wolbachia infection using a PCR assay, and the prevalence of Wolbachia infection was found to be 3.3%, with strains belonging to supergroups A and B.

Summary: In the microspatial environment of Nanjing City, the urban fringe region plays an important role in the dispersion of Aedes albopictus populations between rural and urban areas, and co-infection with Wolbachia A and Wolbachia B is the most common Wolbachia infection status among different regions.

Summary: In this study, we conducted a phylogenetic reconstruction of the Drosophila saltans group using a combined analysis of morphological and molecular markers. The results identified five distinct lineages within the group and proposed a new hypothesis for the phylogenetic relationships among the subgroups. The relationships within some subgroups were well supported, while the saltans subgroup showed several polytomies. The morphological analysis also provided support for the formation of a specific clade. These findings contribute to a better understanding of the evolutionary history of the Drosophila saltans group.

Summary: In our previous studies, we have found that blue light with a wavelength similar to 420 nm is highly effective in controlling populations of the mosquito Culex pipiens form molestus. In this study, we investigated the lethal effects of blue light on the Asian tiger mosquito Aedes albopictus and found that the 417 nm blue light had a strong lethal effect on the larvae, pupae, and adults of this species. However, it had no lethal effect on the eggs.

Summary: This study demonstrates that Aedes detritus may be a competent vector for BATV at 20 degrees C, while Aedes aegypti and Culex pipiens were not competent. The extrinsic incubation period for Aedes detritus appears to be less than or equal to 7 days, potentially increasing the transmission potential of BATV in these populations.

Summary: In Drosophila, Wolbachia are endosymbiotic bacteria that were first discovered causing cytoplasmic incompatibility in the fruit fly Drosophila simulans in the late 1980s. Two models, bistable and Fisherian waves, were proposed to describe the dynamics of infection frequencies based on the prevalence of Wolbachia in American and Australian populations. However, there is limited information about Wolbachia's prevalence and effects in European populations. This study focuses on the high levels of Wolbachia infection frequencies and the potential adaptive traits in a D. simulans population from Odesa, Ukraine.

Summary: This study found that the emergence of D. suzukii decreased exponentially with an increasing proportion of chicken manure in compost treatments, with a reduction of 95% when containing 25% chicken manure. Additionally, Drosophila melanogaster demonstrated a similar response to D. suzukii in the field.

Summary: The study conducted an island-wide survey of mosquito richness on Puerto Rico and Vieques, U.S.A., documenting the occurrence of 44 species and providing information on habitat associations and medical importance. The absence of certain invasive and exotic species was noted, emphasizing the importance of obtaining a complete picture of species present in the context of frequent outbreaks of arboviruses on the islands.

Summary: Wolbachia is a bacterium that can manipulate the biology of arthropods and nematodes in various ways. The strain of Wolbachia in Drosophila melanogaster causes sperm-egg incompatibilities and protects the host against RNA viruses, making it a potential tool for vector control. Research using the Drosophila model has identified metabolic pathways affected by Wolbachia colonization and virus infection, shedding light on the mechanisms of pathogen blocking for effective vector control programs leveraging Wolbachia.

Summary: Honey bees play a crucial role as pollinators in agriculture, but recent declines in their health have raised concerns. The microbial community, specifically a bacterium called 'Parasaccharibacter apium', may influence colony health. Further research is needed to better understand the relationship between these microbes and honey bee health.

Summary: This study characterizes the bacterium Bombella apis associated with honey bee larvae and its impact on their nutritional resilience. The research shows that B. apis is the only bacterium capable of withstanding antimicrobial larval diet and can synthesize all essential amino acids. Analysis of genes reveals the recent acquisition of multiple amino acid transporters in B. apis ancestors. Moreover, honey bee larvae supplemented with B. apis experience less mass reduction under limited nutrition.
