Abstract
Effect of hydroprene, a juvenile hormone analogue (JHA) on the hatchability, population dynamics and organic constituents of C. cephalonica were studied. A concentration of 0.002 ul IGR was found to be effective on hatchability and low dosages result in high percentage inhibition of adult emergence. A significant reduction of (biochemical) organic constituents of treated larvae resulted in formation of many morphological deformities.
