Answer: Spinosad (a biodegradable insecticide).

DDT is non-biodegradable; it persists in the environment and accumulates in food chains. Spinosad, an insecticide produced by a soil bacterium, is effective against insects but degrades easily and is far less toxic to birds and mammals, so it is used in its place. (Other less persistent replacements such as malathion are also used.)
