title: [Effect of delta-endotoxin of Bacillus thuringiensis israëlensis on biochemical functional relationships in Diptera Aedes aegypti].
abstract: A study of the action of very low doses of the delta-endotoxin of Bacillus thuringiensis israëlensis on the larvae of Aedes aegypti (Diptera) gave evidence for peculiar properties of the dose/effect relations based on the variations of the regression slopes of functional relationships between the pairs cysteine/serine and fatty acids/histidine, by contrast with the pair fatty acids/glucose which exhibited a classical shaped relation. This indicates "crypto-toxicological" processes, not lethal by themselves and without pathological symptoms, but able to initiate "pathogen-chaining" mechanisms leading, at the end, to a lethal secondary syndrome.
