Ventral nerve cord remodeling in a stingless bee (Melipona quadrifasciata anthidioides, Hymenoptera, Apidae) depends on ecdysteroid fluctuation and programmed cell death

The reorganization of the ventral nerve cord (VNC) during metamorphosis of M. quadrifasciata was observed to be characterized by shortening of connectives and subsequent fusion of the 2nd and 3rd thoracic and the 1st abdominal ganglia. Also, the 5th to 7th abdominal ganglia came into very close cont...
