The mechanism of compensation in juvenile hormone synthesis following unilateral allatectomy in Diploptera punctata

Following unilateral allatectomy in the viviparous cockroach, Diploptera punctata, the remaining corpus allatum (CA) can synthesize juvenile hormone (JH) at rates equal to that of a pair of control CA. A single CA undergoes changes in volume and cell number similar in magnitude to those occurring during the normal cycle of JH synthesis. There is no hyptertrophy of the CA associated with compensation in JH synthesis. Therefore, the rate of JH synthesis per cell or per unit volume of single CA following unilateral allatectomy is twice that of a single control CA.
