title: Effect of prostaglandin F2alpha on gonadal carbohydrate metabolism of silkworm, Bombyx mori L.
abstract: Effect of prostaglandin F2alpha (PGF2alpha) on carbohydrate accumulation in gonads of the multivoltine silkworm (hybrid: Xinhang x Keming) has been studied by means of topical application to larvae of the silkworm. Increased weights of larvae and reproduction organs, as well as carbohydrate metabolism in gonads of the silkworm, Bombyx mori L. was found after treatment with prostaglandin F2alpha. The increase in weight (larvae 21.9%, testis 28.9%, and ovary 33.3%) was associated with increases in the biomolecules (20-30%) and LDH and aldolase activity (18-25%). The results suggest that the accumulation of carbohydrates denotes a higher extent of utility of the energy sources in function of the testes and ovaries, and the routine application of prostaglandin F2alpha would be helpful in improving the reproductivity and egg quality of the silkworm.
