Abstract：The life diagram of the Blattella germanica in the experimental population with fire different temperature (19°, 22°, 25°, 28°, and 31℃)shows that the optimum temperature is at 25-28℃ for nymphs. The higher or lower temperature will influences 1-3 instars survival. The 4-6 instar nymphs are affected greatly by the lower temperatare. Under 28℃ the rate of the generation survival is 56.1%. The rate of the generation development is 0.016. The nymph nuumber of the Ootheca of a female is 262 in total, but at the temperature of 19℃ is the lowest group comparing with Others. The rate of generation survival and generation growth, and hatching nymphs in total mumber revealed in the tendence of a parabola. The five different temperature and the increasing exponent in population can be shown with quadratic parabolic equation as well. This showed that within the realm of 17.52-37.44℃, the generation namber of the Blattella germanica is in the tendence of rising. The most optimum temperature is 27.48℃. At this coudition the popoalation number is increased 72 times. With the temperature below 17.52℃ or overe 37.44℃ the population number is in the tendence of lower.
