Neural control of spinning and pupation in the silkworm Bombyx mori L.

Neural control of spinning and pupation in the silkworm Bombyx mori was stu died by lesioning one or both robes of the brain. The lesions led to inabil ity of the silkworm to spin the cocoon as well as to pupate. Lesion in the brain would impair neural signals for coordinated movements of the body, an d would prevent orderly release of neurohormones and or neurohumours. Conse quently the silkworm would neither spin the cocoon nor pupate, and conseque ntly dies.
