| Abstract: | Summary WhenPhytoseiulus persimilis was reared withTetranychus urticae, infesting roses propagated in a greenhouse at controlled daily temperatures of 24°C (12 hrs) and 18°C (12 hrs), prey numbers
fluctuated with peaks of increasing amplitude. Differential dispersal of prey and predator species was one factor contributing
to the inability of the natural enemy to control the pest population. |
