Abstract:The rates at which several diarylhaloethanes structurally related to DDT were enzymatically dehydrohalogenated by homogenates of DDT-susceptible and DDT-resistant house flies (Musca domestica L.) were' determined. Diarylbromoethanes were dehydrohalogenated much more readily than similar chlorinated compounds. DDT-susceptible flies exhibited considerable dehydrobrominase activity, possibly sufficient to ac- count for the low toxicity of the bromine analogs of DDT to the insects. No evidence of enzymatic preference for either enantiomorph of a racemic mixture of an optically active substrate was found.
