Extract

Further evidence is provided to show that the head of the desert locust is the most vulnerable body region to the toxic action of malathion (and malaoxon). The circulatory system is shown to play an important part in determining the toxicity of the insecticide by taking it towards or away from the sensitive areas. The rates of absorption, distribution and excretion of 3H-malathion for different applications are given.
