[Activity of the corpora allata of diapausing females of Tetrix undulata (SWRB) (Orthoptera-Tetrigidae)].
The implantation of one or two pairs of corpora allata of diapausing females in another diapausing females (two weeks old) induces vitellogenesis and laying of one, two or three egg-pods in a great number of females. The denervation of the corpora-allata of a diapausing female also induced vitellogenesis. These results suggeste that corpora-allata of diapausing females are not active. The denervation induces the break of the inhibition "travelling" by the corpora-allata-cardiaca nerves or stimulates the corpora-allata.
