Abstract
THE remarkable insecticidal powers of the compound D.D.T. (alpha alpha bis-(4-chlorphenyl)-beta beta beta trichlorethane) have attracted some attention for their theoretical interest as well as for their practical utilization. Two quite independent hypotheses concerning its outstanding toxicity have been published so far. They are alike in ascribing it to a combination of a toxic component of the molecule with a grouping conferring lipoid solubility; but there they part company. Dr. Läuger1 and his colleagues believe that the toxic component is the linked p-chlorbenzene rings, on the grounds that they have found several compounds of this type toxic to insects when ingested.
