| Abstract: | Based on the comparing of population dynamics of single species and mixed population and the intrin- sic rate of increase （rm） when Tetraychus urticae Koch and T. cinnabarinus Boisduval fed with cotton, the inter- species competition were studied. The results showed that it was 38th day when the amounts of active mites and mature mites of T. urticae and T. cinnabarinus reach to peak in the single population ; and it is 48th and 54th day when the amounts of active mites and mature mites of T. urticae or T. cinnabarinus reach to peak in the mixed population, and the amounts of Tetraychus urticae Koch are 1 times higher than that of T. cinnabarinus Boisdu- val. Both in the single population and mixed population, the intrinsic rm of T. cinnabarinus active mites and ma- ture mites was higher than that of T. urticae, which suggested interspecies competition of T. cinnabarinus was higher than T. urticae fed on cotton. |
