Zika virus’s spread adds urgency to gene editing that could allow scientists to program the insects to die off, but the idea is fraught with quandaries.
"Prof. Akbari at UC Riverside is using Crispr/Cas9 to design a gene-drive system that would inactivate a fertility gene in female Aedes aegypti mosquitoes and then pass on the inactivated gene. That would sterilize future generations of females.
He hopes to test the system within the next several months. “We’re working as fast as we can,” Prof. Akbari says."

"Omar Akbari, University of California Riverside: "If you want to destroy a biological kind in the world, for example, Aedes aegypti, the Zika supercarrier, this is now possible A new technique turns off vital genes of the mosquito and spreads itself in a way. . chain reaction Sometime breaks the whole population together - and you have eradicated this way."

"UC Riverside’s Akbari put in a plug for more research dollars in Southern California to develop and test gene drive technologies.“Developing these systems takes a lot of effort and time and they are very complex,” Akbari said. “So funding the right groups would be important, and opening up larger collaborative efforts.
“In California we have a pretty good team of people working on this goal. We have Bruce Hay at Caltech, Tony James at UC Irvine, Ethan Bier, and me. We’re all really close to each other, about an hour’s drive of each lab. So I think having a collaborative grant where we could come together and work on these technologies would be really nice, and we don’t have that yet.”

“We’re taking multiple approaches. The ideal approach would be to eradicate the pest—develop a catalytic gene drive system that you could release into a population that can spread invasively,” says Omar Akbari, a molecular biologist at UC Riverside. “And as it spreads, the population declines without the use of insecticides.”

Professor Akbari said this about Zika and the Olympics:
“It is estimated that 1/2 million visitors will travel to Brazil for the 2016 Olympics, and it is important that these travelers exercise extreme caution as related to Zika. In Brazil, Zika still poses a significant threat with a total of 166,000 suspected cases, and counting, thus far. As recommended by the CDC, pregnant women should avoid the games completely, and individuals with pregnant partners should abstain from sexual contact for the duration of the pregnancy, and upon returning home from the games. In addition, all visitors should take the necessary steps to prevent mosquito bites, both during the games and for several weeks after returning home.”

Professor Akbari said this about gene drive recommendations:
Dr. Omar Akbari, Assistant Professor of Entomology, University of California, Riverside (webpage):
Expertise: Genetics and physiology of mosquitoes, genetic control technologies for limiting mosquito-borne diseases
“The NAS report does a commendable job at overviewing the technologies and identifying the knowledge gaps and barriers that will be important to address before any gene drive approach can be tested and utilized in the environment.
“As they conclude, and I agree, the potential applications of gene drives are quite exciting, however, the science is still premature and there are far too many unanswered questions to justify the release of a gene drive beyond the laboratory or contained field trials. Therefore, the committee urges caution until we understand better the ethical, regulatory, scientific, social and environmental consequences of unleashing gene drive containing organisms freely into the environment.
“To address these issues, the committee recommends that phased field testing, robust ecological risk assessments, and public engagement will be essential components for moving any gene drive from the laboratory to the field, and I generally agree with these recommendations. The committee also points out that regulation of gene drives will likely fall under the Coordinated Framework for the Regulation of Biotechnology. However, the federal agencies included in the current Coordinated Framework (FDA, USDA, EPA), do not have clear lines of authority over the potential applications of gene drive research.
“This issue of who will govern a technology that has no boundaries and can persist in the environment long-term will be very important address as this technology develops further in various species. Overall, this is a highly complex issue and the committee’s recommendations for a cautionary, collaborative, and multi-disciplinary, approach to future research and governance of gene drives is a good one.”

"DEET is the oldest option. It was produced by the military and has been on the market since the gold standard...It has gone through the most tests."

Professor Akbari on using male-killing bacteria to control insects:
“Understanding the molecular mechanisms of how this bacterium can bias sex ratios of insects could have downstream implications in other insects and these mechanisms could potentially be exploited to control insect species in the future.”

Professor Akbari on the reasoning behind releasing GMO mosquitoes to fight Zika:
"Though small, and seemingly insignificant, mosquitos are among the most dangerous creatures on earth. They are the primary vectors for major diseases such as dengue fever, malaria, yellow fever and Zika, which infect hundreds of millions of people throughout the world, killing millions every year."

Professor Akbari on the efficiency of releasing massive amounts of genetically modified mosquitoes:
"The only limitation of that approach is that it requires what I call an inundation, continuous release, every generation, of a large number of these males, up to 20 times the population size. As you can imagine, that's a significant undertaking and requires a huge effort."
