The U.S Has Launched Genetically Modified Mosquitoes To Combat Dengue And Zika Virus The new genetically modified mosquitos will aid in killing the disease-carrying species of mosquitos. In a new technique to fight back the disease-carrying mosquitos like dengue, the U.S is working on genetically engineered mosquitos that would kill the harmful counterparts. Oxitec is the biotechnology company introducing the U.S with the new species of mosquitos, the idea of which seems a little controversial to start with, given the current pandemic situation and how it all started after a man allegedly ‘had a bat to eat’. However, the concern just stands as an assumption.
