Title: The Comparison on Fecundity of Tetranychus turkestani and Tetranychus truncatus
Abstract: The fecundity table of Tetranychus turkestani and Tetranychus truncatus reared with cotton leaf disk were constructed at 25 ℃. We observed survial rate and fecundity, compared fecundity parameters such as net reproduction rate(R0), intrinsic rate of increase(rm), finite rate of increase (λ), population doule time(t), trend index of population(I) .The results indicated that the fecundity and trend index of population of T. truncatus were lower than that of T. turkestani. As a result, we can estimate the factors that cause the outbreak of T. truncatus on cotton field is not its fecundity potential but others. As life time of T. truncatus wwas longer than T. turkestani, it can cause more damage once it came into cotton filed.
