[Ultrastructural changes in the corpora allata of the last larval instar of Choleva angustata Fab. (Catopidae). The effect of fasting, with or without ecdysterone].
Fasting experiments show striking changes at the ultrastructural level in the corpora allata of the last larval instar of Choleva angustata Fab: increase of the glandular volume and development of the smooth reticulum. These findings suggest that fasting leads to a continuous activity of the corpora allata.
