Some of the most acute challenges that the world faces now and in the foreseeable future are caused by insects and mites that seriously threaten human health and food security. Their control is primarily achieved by the use of insecticides: for example, malaria prevalence has halved since 2000, saving 660 million lives, with 80% of the reduction being attributable to the use of insecticides. However, both the limited availability of low risk insecticides and insecticide resistance represent a major threat, and there is an urgent need to develop new insecticides. CypTox will apply biotechnology excellence to exploit the cytochrome P450 (CYP) metabolic/detoxification pathway of target and non-target organisms, to develop novel insecticides, efficient against selected insect & mite major pests and vectors, but are highly selective and safe for mammals, pollinators and the environment.
