Abstract

The mid gut of the parasitized larvae was decreased in diameter
compared with unparasitized ones. Th epithelial cells were loose, full with
vacuoles, turned to folds more thick and faintly stained. The tracheols
occupied a considerable space of the perivesceral protein of the body cavity
of the parasitized larvae. The parasitized Spodoptera littoralis larvae showed
parasitogenic degeneration in their fat bodies.
