Experiments were carried out to remove existing doubts about the toxicity (and therefore cost per unit killing power) of malathion to adults of Schistocerca gregaria (Forsk.) which have arisen from earlier field and laboratory tests. Malathion is shown to be almost as toxic to these insects as γ-BHC, but superior in speed of action. These observations are in agreement with the performance of these two compounds in the field.Subdivision of a dose of malathion with simultaneous application at two loci increased its toxicity. This, as well as other factors, brings the value of LD50 determinations into question. Recommendations for large-scale use of new insectsicides, based only on laboratory data, may not always be reliable.
