As to the high polarity, high boiling point resultant—trimesic acid, the analysis methods of infrared spetrum, gas chromatography-mass spectroscopy, vapour-phase chromatography, acid number titration and so on are seperately used to characterize its property. Infrared spetrum and gas chromatography-mass spectroscopy are used to have a qualitative analysis on the resultant and are compared with the stand diagram. Sulfuric acid-methanol esterification and rapid esterification are used to prepare the trimesic acid trimethyl-ester and have a FID quantitative analysis. So that we make sure the purity of trimesic acid in the resultant and also we have an acid alkali titration on the resultant to get its acid number, in order to verify the purity of trimesic acid in the resultant.

Both the proteins components contained in haemolymph, fat body and ovary and the kenetics of the vitellogenin in haemolymph and ovary were analyzed by SDS—polyacrylamid electrophoresis, Ouchterlony plate tests and Rocket—immuno—electrophoresis. The results showed that the vitellogenesis initiated in adult stage and the Vg in haemolymph was detected firstly at 48h after eclosion. The titer of Vg in haemolymph raised rapidly in following 3 days and almost at the same time the vitellin appeared in oocytes. It was taken about 4—7 days after eclosion for the first eggs to grow up to the matured statics and to be laid out.
