Document Summary
Paper for today mosquitoes were not created with a drive" motive. Drive via wolbachia symbionts that cause cytoplasmic incompatibility. Sterile insect approaches: release many males that will interfere with successful reproduction of females in the wild. Suppresses but does not cause long-term genetic changes in wild populations. Not replacing just getting rid of insect altogether. Sterile male technique: first used successfully to control screwworm fly, a serious pest of livestock. Males treated in the lab with radiation and then mass released rendered sterile but still capable of mating. Starting in florida, airplanes released 50 million sterilized male flies every week, screwworms were eliminated from the southeast us by 1959 (completely eradicated in 1991). Separating m and f in lab is costly, methods to produce only males are being developed. Other sterile male approaches: using microbes that cause cytoplasmic incompatibility. Using transgenic males with a conditional dominant lethal mutation. Release of insects carrying a dominant lethal allele (ridl).
