Abstract： 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.
