Scientists have developed a toolkit that helps pave the way to a gene drive designed to stop Culex mosquitoes from spreading disease. Culex mosquitoes spread devastating afflictions stemming from West Nile virus, Japanese encephalitis virus and the pathogen causing avian malaria.
In a new study, researchers found that night- versus day-biting species of mosquitoes are behaviorally attracted and repelled by different colors of light at different times of day. Mosquitoes are among major disease vectors impacting humans and animals around the world and the findings have important implications for using light to control them.
Scientists have identified the chemical cues in flowers that stimulate mosquitoes’ sense of smell and draw them in. Their findings show how cues from flowers can stimulate the mosquito brain as much as a warm-blooded host — information that could help develop less toxic repellents and better traps.
Patches of standing water that are close together are more likely to be used by mosquitoes to lay eggs in than patches that are farther apart, according to a new study from the University of Georgia.
