[Allatecotomy and imaginal diapause in female Tetrix undulata (Sow.) (Orthoptera, (Tetrigidae)].
Allatectomised females (whose diapause has been broken by chilling) do not lay though sham-operated or unoperated or unoperated controls do lay: corpora allata are essential for maturation. Ovocyte size is the same for allatectomized females as for diapause females. So it seems that the lack of ovocyte development might be the result of the inactivity or inhibition of corporal allata.
