Summary: This study analyzed the seasonal variation of midgut bacterial diversity of Culex quinquefasciatus in southern China. The results indicated that the Bacteroidetes communities were more abundant in autumn and winter, potentially playing a role in the nutritional supply of adult mosquitoes when temperatures drop. The study provides valuable insights for disease control strategies targeting Cx. quinquefasciatus.

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 southern house mosquito uses two odorant receptors, CquiOR10 and CquiOR2, to detect oviposition attractants skatole and indole. Through mutation experiments and structural modeling, it was found that a single amino acid substitution can alter the specificity of the receptors, leading to finely tuned volumetric space to accommodate specific oviposition attractants.

Summary: The study identifies an odorant receptor (OR) in the southern house mosquito that responds to both odorants and inhibitory compounds. They also discover different currents in two other receptors in response to different odorants. Additionally, they find that gamma-octalactone shows strong repellency activity.

Summary: Mosquito-borne diseases pose a significant public health issue, with vector control being crucial for reducing their spread. However, insecticide resistance is a growing concern, prompting research into alternative solutions like using rhamnolipids and clove oil emulsion. Experiments have shown that these solutions have high toxicity against Aedes aegypti and Culex quinquefasciatus, with significant mortality at higher concentrations.

Summary: The objective of this study is to determine the spatiotemporal distribution of vector mosquito species in Maricopa County, AZ from 2011 to 2021 and identify hotspot areas for West Nile virus and St. Louis Encephalitis virus transmission in 2021. The results show that vector mosquito species are widely distributed and abundant in the urban areas of Maricopa County. The findings of this study can be used to inform vector control operations.

Summary: This study investigates the transcriptomes of the Avian malaria parasite Plasmodium relictum in its vector Culex pipiens quinquefasciatus, revealing gene expression patterns at different key timepoints and highlighting the presence of highly stage-specific pathways throughout the infection. Analysis identified genes related to host-immune invasion, unknown functions, and potential multifunctionality of some proteins, shedding light on the molecular mechanisms of the parasite's development and gene regulation diversity in its vector stages.

Summary: The Southern house mosquito Culex quinquefasciatus uses its olfactory system to locate human hosts for blood meals, transmitting deadly diseases in the process. The organization of glomeruli in the antennal lobe governs the insect's odor identification and discrimination, with specific connections between receptors and glomeruli shaping behaviors. Studies on the 3D structure of the antennal lobe provide insights into mosquito odor coding and signal processing mechanisms.

Summary: The study in Yaounde, Cameroon, revealed high resistance of Culex quinquefasciatus populations to bendiocarb and malathion, as well as to permethrin and deltamethrin. Molecular analyses identified various mechanisms of insecticide resistance, including mutations and gene overexpression. The findings underscore the importance of implementing integrated vector control strategies in urban environments to combat insecticide resistance in Culex populations.

Summary: This study investigated the larvicidal effects of essential oils from the Citrus family and their major ingredient, limonene, on mosquito vectors. The efficacy was then improved by preparing nanoliposomes containing these oils. The results showed that the nanoliposomes had a stronger larvicidal effect. Nanoliposomes containing Citrus aurantium essential oil exhibited the best activity against Anopheles stephensi and Culex quinquefasciatus.

Summary: This study provides insight into the composition and diversity of fungal communities in field-collected Cx. restuans and Cx. pipiens larvae using OTUs and ASVs. The larval breeding site is the major determinant of fungal community assembly in these mosquito species. There are also distinct fungal communities in the guts and carcasses of each species, with less tissue-specific patterns in Cx. restuans larvae compared to Cx. pipiens larvae.

Summary: The study reveals that the insect repellent methyl salicylate and eucalyptol have different effects on an odorant receptor in the southern house mosquito. Variations in the receptor protein determine the strength of inhibitory responses. The findings suggest that odorants and inhibitors may bind to the same pocket and that these responses are mediated by cations.

Summary: The study investigated the effects of the biological larvicide Bacillus thuringiensis var. israelensis (Bti) on Culex oviposition and nontarget species. The results showed that Bti effectively reduced larval density and survivorship of Culex mosquitoes without affecting nontarget insects. Additionally, Bti stimulated phytoplankton density but reduced herbivore density.
