biotech company Oxitec has developed a modified version of the diamondback moth, which could lead to the pest’s extinction. Diamondback moths, the most resistant of all insects to pesticides, can wipe out entire fields of cold weather crops including, broccoli, cabbage, canola, cauliflower, and kale, resulting in billions of dollars in lost crops each year. The Oxitec diamondback moths contain a lethality gene, which when they mate with moths in the wild, prevents the female offspring from developing, so they die as larvae, with half male offspring in each generation inheriting the “lethality” gene meaning the entire population declines over each generation. //
Oxitec’s mosquitos have been modified so when they mate with females, their offspring are incapable of surviving to adulthood. Laboratory tests and field tests have indicated widespread introduction of this mosquito could dramatically reduce the population of the disease-spreading mosquitoes.
Federal government and state regulators in Florida recently approved the introduction of Oxitec’s mosquitos into a small area of the Sunshine State. This follows the actions of the governments of Brazil, the Cayman Islands, Malaysia, and Panama, which have allowed Oxitec to release its bioengineered mosquitos at selected sites. Brazil reported mosquito populations fell by at least 90 percent in the locations Oxitec’s mosquitos were released in the year following their introduction. //
Unfortunately, environmental extremists have targeted genetically modified products for extinction, fighting to delay the approval of or suing to block the introduction of bioengineered products, saying genetic engineering is akin to “playing God.”
While caution must be exercised with the introduction of any new technology, genetic engineering carries much promise, and the crops and animals developed using it are the most intensively studied and tested technologies ever to be produced. If the search for a COVID-19 vaccine is teaching us anything, it is that too much caution can be as deadly or even deadlier than too little caution. With millions of lives on the line, research and regulatory approvals should be expedited, not delayed.
If environmental fear-mongers successfully block the use of bioengineered animals, they will be condemning millions of people to unnecessary suffering and early deaths—now that would be playing God (or the devil) with a vengeance.
