[pH variations in the midgut of Aedes aegypti in relation to Bacillus thuringiensis var. israelensis (serotype H14) crystal intoxication].
After feeding Aedes aegypti larvae with B. thuringiensis var. israelensis crystals the very alkaline pH (greater than or equal to 10) of the anterior midgut remains stable during the first twenty minutes, in spite of important cytological damage. Thereafter, the pH drops to surround the neutrality and the death occurs. These results are discussed according to the knowledge on the action of B. thuringiensis var. israelensis.
