Abstract: Objective:To study the protein composition in haemolymph and ovary of the German cockroach.Methods:Polyacrylamide gel electrophoresis(PAGE).Results:(1)The compositions of female-specific haemolymph protein were S 14,Rc 15,Rp 15 and Rz 15 belts respectively.S and R strains had two identical primary belts,whose ratios of movement were 0.18,0.29 respectively.R strain was one belt more than S strain,which ratio was 0.14.(2)Those of male-specific haemolymph protein were S 9,Rc 10,Rp 10 and Rz 10 belts respectively.They had one identical primary belt,whose ratio of movement was 0.32.R strain was also one belt more than S strain,which ratio was 0.6.(3)The compositions of egg proteins all were 13 belts.The belts of R strains were lighter on colour and narrower on width than those of S strain whose ratios of movement were the same.They had one identical primary belt,whose ratio of movement was 0.27.Conclusion:The increasing belts of haemolymph protein were related to resistance probably.The belts of egg protein whose quantity were reduced caused that the ratios of the reproduction and the incubation were cut down probably.
