Abstract: The mating behavior between the female and male of Apriona germari Hope with the similar physiological status was observed. The reproductive systems of both sexes, including male reproductive system, male accessory gland and ovary, were isolated and described. The contents of the total carbohydrate and protein in reproductive systems and the hemolymph from both virgin and mated male and female were also tested by anthrone colorimetry and Folin-phenol methods. The results showed that in males one hour after mating, the contents of the total carbohydrate and protein in the reproductive system both increased, the content of protein in the hemolymph decreased by 21.38%, and the contents of the total carbohydrate and protein decreased by 81.76% and 63.76%, respectively, in the male accessory glands which secreted some special proteins used as the mating factors. As for females, the total carbohydrate and protein in haemolymph and ovary both increased during the whole mating process. The company behavior of the male, which would be an important part of its reproductive strategies, would last over 4 h.

Key words: Apriona germari, mating behavior, total carbohydrate, total protein
