Laboratory evaluation of malathion for controlling the Desert Locust, Schistocerca gregaria (Forsk.)
Bulletin of Entomological Research 59 (1), 113-117
Abstract: Experiments were done to remove existing doubts about the toxicity (and cost-per-unit killing power) of malathion to adults of Schistocerca gregaria, which have arisen from earlier field and laboratory tests. Malathion is shown to be almost as toxic to locusts as BHC, but superior in speed of action, which is in agreement with the relative performance of these two compounds in the field. The toxicity of a dose divided into two equal drops applied simultaneously to both hind-wing bases was significantly greater than that of the same dose applied as a single drop to one hind-wing base. This, as well as other factors, brings the value of LD50 determinations into question. Recommendations for large-scale use of new insecticides, based only on laboratory data, may not always be reliable.
