Abstract
The alkaline and acid phosphatases were demonstrated histochemically along the whole length of the silk gland in normal and paralysed larvae of the rice mothCorcyra cephalonica. The activity of both enzymes was found to be much reduced as a result of the toxin injected in the host's body by the parasiteBracon hebetor.
In both the normal and paralysed larvae the two enzymes were found to be more intense in the nuclei than in the cytoplasm.
Both enzymes could not be detected in the cells of the productive tube region of the glands in paralyzed larvae.
Résumé
On a prouvé par histochimie la présence de phosphatases alcalines et acides tout le long de la glande sericigène des larves deCorcyra cephalonica Staint normales ou paralysées parBracon hebetor. L'activité des deux enzymes se trouve très réduite à la suite de l'injection dans le corps de l'hôte de la toxine du parasite. Dans les deux cas, les deux enzymes sont plus importants dans les noyaux que dans le cytoplasme. Les deux enzymes ne peuvent être détectés dans les cellules de la région sécrétrice des glandes des larves paralysées.
