中文摘要： 本文对桑天牛Apriona germari Hope产卵分泌物和各生殖器官内容物的鲜重、蛋白质、还原性糖、游离氨基酸等含量进行了测定及对比分析，结果表明，产卵分泌物鲜重与输卵管萼内容物鲜重差异显著，而与交配囊、受精囊腺内容物鲜重差异不明显；产卵分泌物的蛋白质含量显著高于输卵管萼内容物的蛋白质含量；产卵分泌物的还原性糖含量显著低于交配囊内容物的还原性糖含量；产卵分泌物的游离氨基酸含量显著高于交配囊内容物中游离氨基酸含量。产卵分泌物中蛋白质、还原性糖、游离氨基酸等的含量与受精囊腺内容物相应成分含量均无显著差异，即受精囊腺是其贮藏器官。
英文摘要： Apriona germari Hope female adults were dissected just after the oviposition secretion had been collected and samples of the contents of the bursa copulatrix,the calyx and the spermathecal gland were obtained and analysed.The fresh weight and percentage weight of protein,reducing sugar and free amino acids of the secretion and the contents of the sampled organs were determined.Significant differences were observed in the fresh weight of the oviposition secretion and the content of the calyx.However there was no significant difference in fresh weight between the oviposition secretion and the content of other reproductive organs.Percentage weight of protein in the oviposition secretion was much higher than that in the content of the calyx.Percentage weight of reducing sugar in the secretion was obviously lower than in the content of the bursa copulatrix.The oviposition secretion had a higher percentage weight of free amino acids than the content of the bursa copulatrix.There were no significant differences in the percentage weight of protein,soluble sugar and free amino acid between the oviposition secretion and the content of the spermathecal gland.These results suggest that the oviposition secretion is stored in the spermathecal gland.
