Abstract
We looked at the effect of the presence of pollen (Typha latifolia) on the functional response of Typhlodromus pyri (Phytoseiidae) to Panony chus ulmi (Tetranychidae) in the laboratory. We found that pollen sign ificantly reduced the predation rate but that the magnitude of the eff ect was not large. Over the lower range of prey densities the effect a ppeared to be due to a decrease in search efficiency.
