Washington: Scientists have found anenvironmentally friendly way to curb the transmission ofdengue fever that affects nearly 100 million people across theglobe every year.Researchers from University of California in Irvine andUniversity of Oxford have developed a new strain of mosquitoesin which females cannot fly and males are unable to bite andwhen these genetically altered insects mate with wild ones,they pass on their genes.
The dengue virus is spread through the bite of infectedfemale Aedes aegypti mosquitoes, and there is no vaccine ortreatment.The team said, new breed of flightless females areexpected to die quickly in the wild, curtailing the number ofmosquitoes and reducing or even eliminating denguetransmission, while males of the strain can fly but do notbite or convey disease."Another attractive feature of this method is that it`segalitarian: All people in the treated areas are equallyprotected, regardless of their wealth, power or education,"they said.Using concepts developed by Alphey, the researchers madea genetic alteration in the mosquitoes that disrupts wingmuscle development in female offspring, rendering themincapable of flight.Males` ability to fly is unaffected, and they show no illeffects from carrying the gene.Bureau Report
