Abstract: | Production of molecules with toxic activity by genetically transformed symbiotic bacteria of pest insects may serve as a powerful
approach to biological control. The symbiont, Enterobacter gergoviae, isolated from the gut of the pink bollworm (PBW), has been transformed to express Cyt1A, a cytolytic protein toxin lethal
to mosquito and black fly larvae, as a model system. These transgenic bacteria might be used to spread genes encoding insecticidal
proteins to populations of agricultural insects or as replacement for chemical insecticides such as malathion used in bait
formulation to control specific insect pests, because of extreme public pressure against organophosphate pesticide spraying.
