Résumé
Flight muscles of male moth, B. mori seem to utilize carbohydrate preferentially as a source of energy for all its acrobatic movements during the search for female moth. Depletion of triacylglycerol from flight muscles without affecting its level from fat body suggests that this lipid fraction serves as a source of energy in flight muscles during insemination processes. Significant depletion of triacylglycerol and glycogen from flight muscles of female moth after egg laying indicates that they are used to meet the energy requirement of female during oviposition activity. Depletion of proteins from flight muscles of male and female insects suggest that these proteins are transported to the accessory reproductive glands to meet their protein demand.
