Ren Shaoting; Gao Qingyi ; Zhu Daoyu (Biology Department,Heze Teacher's College, Heze 274015)  
Temperature obviously affected the incubation rate and the sexual development of Trionyx sinensis . We found that the incubation rate was promoted as temperature went up,and the rate could amount to 100% at the optimum temperature. The sex rate also changed as temperature did. Within the limit of 24℃~32℃,the incubation rate of female bodies decreased as the temperature went up,but that of male bodies promoted. Incubation rate of female bodies could reach 95% at 24℃,and that of male bodies could attain 85% at 32℃
