Summary: Recent studies have shown that the population growth of North American rock pool mosquito, Aedes atropalpus, is negatively impacted in colder temperatures, while it is highest at intermediate temperatures. The developmental success of A. atropalpus at intermediate temperatures suggests competition with Ae. j. japonicus in rock pools within that range may significantly impact natural Ae. atropalpus populations. This study highlights the importance of developmental temperature in affecting the population growth and fitness of Aedes atropalpus.

Summary: This study evaluated the effects of various compounds on Ae. albopictus, showing that some compounds significantly affected larval survival and development, with potential for use as bioinsecticides. Due to the mosquito's role in spreading important human diseases, the findings of this research are globally significant.

Summary: Genetic variation of Aedes japonicus japonicus populations in Belgium and Germany was investigated, showing differences before and after elimination campaigns in Natoye. Specimens collected after 2017 displayed increased genetic diversity, suggesting new introductions. A relation with the western German population was found at the Belgian border.

Summary: This study reports the diapause and seasonality of a field population of Aedes japonicus in the northeast of France, finding effective diapause ability and a 100% diapause incidence rate at the end of summer. Additionally, a positive correlation between egg size and diapause incidence was observed, but morphology alone cannot accurately predict diapause status.

Summary: The study found that the winter-spring period is crucial for the seasonal population density development of Aedes albopictus, with a temperate winter and dry/cold March, followed by a rainy and hot spring, as well as a rainy July, favoring the seasonal development of the species.

Summary: The study investigates the microbiome of Ae. albopictus populations in Germany and identifies RNA fragments of various viruses and microorganisms, with differences between male and female mosquitoes. Understanding the presence of microorganisms in mosquitoes can contribute to the development of new approaches to vector control.

Summary: Research has shown that 55% of the 20 Florida Ae. aegypti populations tested exhibit metabolic resistance, with 73% showing significantly increased mortality when exposed to a combination of DEF and permethrin, 64% with PBO and permethrin, and 55% with DM and permethrin. These findings suggest that metabolic enzyme inhibitors like DEF and DM could be effective additives in permethrin products to combat resistant Ae. aegypti mosquitoes.

Summary: Both male and female mosquitoes consume sugar meals for energy, and targeting this behavior through attractive toxic sugar baits (ATSBs) can be an effective and environmentally friendly method to control mosquito populations. The study found that Aedes j. japonicus fed on various fruit solutions and experienced mortality when exposed to a toxic sugar solution containing boric acid, indicating the efficacy of boric acid as an oral toxin against this mosquito species. Further field experiments will be conducted to assess the efficacy of ATSBs and potential impacts on non-target species.

Summary: This study presents a product profile and key trial results of a male Aedes sound trap, finding that factors such as the presence of a black base and entrance size significantly influence male capture rates, while sound lure volume and frequency do not have a significant impact on catch rates.

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: The study found that Aedes albopictus had higher susceptibility to insecticides compared to Aedes aegypti, and mosquitoes kept at different temperatures exhibited varying levels of susceptibility to insecticides. The results suggest that public health officials should consider the temperature effects when controlling mosquitoes with insecticides.

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 found that the host species and larval sampling environment are important determinants of bacterial community composition and diversity in mosquito larvae. Aedes triseriatus and Aedes japonicus harbor distinct bacterial communities that differ from water samples.

Summary: This study found that different larval rearing densities affect TAG reserves, fecundity, and size of Aedes aegypti, with higher density rearing leading to greater TAG storage, higher resistance to fasting, and more eggs laid. Insects reared in higher densities were also larger in size.
