Cartography of odor chemicals in the dengue vector mosquito (Aedes aegypti L., Diptera/Culicidae). | LitMetric

AI Article Synopsis

  • * Researchers compared compounds from different life stages and tissues of male and female mosquitoes, discovering significant amounts of certain esters linked to sex and age.
  • * Findings indicate that specific compounds increase during the late larval stage and in older adults, which could help identify molecules that influence mosquito behavior for targeted control strategies.

Article Abstract

This study was aimed to identify the chemical compounds of Aedes aegypti that can be potentially used to develop pheromone-based vector control methods. In this study, we compared the chemical compounds collected from the organs of mosquitoes at different developmental stages in the life cycle. We also compared the composition and amount of extracts from the different tissues of male and female adult mosquito. Interestingly, we found large amount of C17-C20 ethyl and methyl esters in the wings of female and antennae of male mosquito. We also found that isopropyl esters, dodelactone, octadecenoic acid and medium-chain fatty acid increase drastically during the late larval stage (L4). Old adult mosquitoes showed remarkable increase in production of C16:1 and C18:1 methyl esters, as a first example of chemical signatures specifically associated with aging in the animals. This knowledge may open the ground to find new behaviorally-important molecules with the ability to control Aedes specifically.

Role of Vigilin and RACK1 in dengue virus- interactions.

Vigilin is a large and evolutionary conserved RNA-binding protein (RBP), which can interact with RNA through its KH domain. Vigilin is, therefore, a multifunctional protein reported to be associated with RNA transport and metabolism, sterol metabolism, chromosome segregation, carcinogenesis, and heterochromatin-mediated gene silencing. The receptor for activated C kinase 1 (RACK1) is another highly conserved protein involved in many cellular pathways.

COMPARING DETECTIONS OF AEDES AEGYPTI FEMALES USING THREE TYPES OF AUTOCIDAL GRAVID TRAPS.

We compared the number of Aedes aegypti females per trap and the number of detections of this mosquito species per week during 8 wk in 3 types of autocidal gravid traps, the Centers for Disease Control and Prevention (CDC) Autocidal Gravid Ovitrap (AGO), Biogents Gravid Aedes Trap (GAT), and Singapore Gravitrap (SGT), in central Puerto Rico. These traps use the same principles for attracting gravid Ae. aegypti females as traditional ovitraps, such as dark colors, standing water, and decomposing plant materials.

Larval competition between the invasive Aedes aegypti (Diptera: Culicidae) and the Caribbean endemic Aedes mediovittatus (Diptera: Culicidae) from Puerto Rico, USA.

Competition between mosquito species during the larval phase is a well-established mechanism structuring container mosquito communities, with invasive species often outperforming natives. We assessed the competitive outcome between 2 species that occur on the island of Puerto Rico, the historic invasive Aedes aegypti (L.) and the endemic Aedes mediovittatus (Coquillett) (Diptera: Culicidae).

Juvenile hormones (JHs) are farnesoic acid-derived sesquiterpenoids that play a crucial role in regulating various developmental processes in insects. Based on these reported biological activities, JHs and their synthetic analogs have been utilized as insecticides with significant commercial success over the past years. Here we describe the engineering of the JH pathway of the yellow fever mosquito (Aedes aegypti) by transient gene expression in the plant Nicotiana benthamiana.
