Title: Effect of temperature on the population growth of Tetranychus urticae in laboratory
Abstract: The two-spotted spider mite,Tetranychus urticae Koch,was fed with cherry leaves in laboratory.Life tables of laboratory population were constructed at 15,20,25,30,and 35℃,respectively.The results showed that the developmental rate increased with the increasing temperature from 15℃ to 35℃,and the relationship could be simulated by Logistic model.The threshold temperatures and the effective accumulated temperatures required for the whole generation were 11.85℃ and 170.39 degree-day,respectively.According to the life tables of the laboratory population,the intrinsic rate of increase(r_m),net reproductive rate(R_0),finite rate of increase(λ),mean generation time(T),and days for population to double(t)were established at different temperature.
