Abstract: Objective In order to investigate the functions of IGRs to growth and reproduction of Bllattella germanica,the sterilization of chitin synthesis inhibitors against Bllattella germanica was studied too.Methods Contacting and bait methods were used and the pathology changing of CA,fat body and reproductive system were observed under stereomicroscope and microscope.Contents of the protein in ovary,DNA and RNA in ovary and spermary were determined.Results Chitin synthesis inhibitors have some juvenile hormone effect.The two are unite efforts in Bllattella germanica.Fat body is one of the target to IGRs,the contents of DNA and RNA in spermary,RNA and protein in ovary increased all but the content of DNA in ovary decreased.Conclusion The sterilization of the Chitin synthesis inhibitors in male Bllattella germanica may be related to the chitin blocking but not to the hindering of RNA and DNA,the sterilization in female Bllattella germanica may be related to the decreasing of DNA in ovary.
