Bliotech firm behind CRISPR mosquitoes is working on other gene-hacked creatures

Brazil’s regulatory agency CTNBio gave Oxitec and Bayer the approval they needed to launch a field test of the gene-hacked armyworm ­— technically a caterpillar — on commercial crops, so there may be genetically altered bugs crawling across corn farms in the area soon. For years, Brazilian farmers have been trying to control fall armyworms with chemical pesticides. But as the pests grew to resist the sprays — which were already difficult to time in a way that actually impacted the nocturnal insect — they had to spray more and more harmful chemicals in the environment, according to Zenger‘s reporting. If Oxitec’s technology works — there’s reason to doubt that its similar mosquito tech does what the company claims — then that excessive pesticide spraying may be able to stop. “Our technology potentially reduces the need for additional pesticides in the long term,” Oxitec head of agricultural programs Neil Morrison said, according to Zenger. “Besides reducing populations of the pest, it also has the potential to slow the resistance development to insecticides and biotechnology enhanced crops.
