Abstract：The contents in male accessory glands of Apriona germaric(Hope) were studied. The results showed that the percentage of total protein, carbohydrate, treholase, and free amino acid of fresh weight of all accessory glands was 8.39% 4.21%, 0.50%, 0.25% respectively. There were the highest contents of four materials in lowaged male beetles. With increase of male adults age, the contents were decreased gradually. The contents of male accessory glands were transferred into female during the mating. After copulation, the contents of the total carbohydrate, trehalose and free amino acid was declined, but the content of the total protein was increased first and then dropped. It took 48 h to recover the content of protein at the level of unmated male. There were deferent changes of four materials in the big and the small tube of male accessory glands during the mating.
