The team, led by FIU biologist Matthew DeGennaro, identified(确认，鉴定) the guilty receptor as Ionotropic Receptor(亲离子受体) 8a, or simply(简称) IR8a, through a process of elimination that began in 2013 when DeGennaro was able to create the world's first mutant mosquito, removing(移除) a gene to investigate how its absence(缺席) affected the insect.
