Article Synopsis
  • Large household water storage containers are key breeding sites for Aedes aegypti mosquitoes, which spread diseases like dengue.
  • Concerns over insecticide resistance and safety are challenging effective mosquito control, leading researchers to explore RNAi-based yeast larvicides as a solution.
  • A study developed a shelf-stable, controlled-release yeast formulation that shows promise for lasting mosquito control, demonstrating effectiveness in various container sizes and remaining active for up to six months.

Dengue and other arboviruses remain a global threat, and enhanced efforts to control the mosquitoes that transmit them are urgently needed. A survey of potential manmade (L.) and (Skuse) oviposition containers was performed in four communities near the end of the typical dry season in 2018 in Trinidad, West Indies.

Background: Although whole-genome sequencing (WGS) is the preferred genotyping method for most genomic analyses, limitations are often experienced when studying genomes characterized by a high percentage of repetitive elements, high linkage, and recombination deserts. The Asian tiger mosquito (Aedes albopictus), for example, has a genome comprising up to 72% repetitive elements, and therefore we set out to develop a single-nucleotide polymorphism (SNP) chip to be more cost-effective. Aedes albopictus is an invasive species originating from Southeast Asia that has recently spread around the world and is a vector for many human diseases.

is a primary sylvan vector of yellow fever virus and the emerging Mayaro virus. However, despite its medical importance, there is a dearth of data on the molecular taxonomy of this mosquito species. In this study, DNA barcoding analysis was performed on 64 adult female mosquitoes from Trinidad morphologically identified as The mitochondrial (COI) gene and ribosomal DNA internal transcribed spacer 2 (ITS2) region of the mosquitoes were PCR amplified and sequenced, and molecular phylogenies inferred.
