Abstract: The curve surfaces of time temperature mortality and time moisture mortality of Beauveria bassiana conidia were processed by complementary log log (CLL) model. Hosmer Lemoshow testing showed that the regression of obtained function was significant, and t test indicated that the parameters of the models reached significant level(P<0.0001). The comparisons of each correspondent LT 50 values in effective time zone showed that it was higher when estimated by single factor analysis than by CLLmodel at different bathing temperature, and at different moisture content, the values estimated by single factor analysis were higher at low moisture contents (RH<33%) or lower at high moisture contents (RH>44%). Comparing with the traditional analysis methods, CLLmodel could provide the information of functional effect affected by time, and of time effect affected by functional factors as well.
