5. Oklahoma State University Insect Management Projects at OSU, 2004 Have recruited a graduate student to conduct a project looking at the role that Phyllophaga white grubs have on golf courses.

6. Oklahoma State University I have received questions over the last few years regarding zoysiagrass mites on residential lawns. We attempted to conduct an acaricide screening study at the Plant Pathology farm this past summer Eriophyiod Mites

7. Oklahoma State University We were unable to find a method to extract and count the mites from the turf. The mites “disappeared” during mid summer, then reappeared in early fall. We are going to set up some studies to further understand what is happening with these mites. Eriophyiod Mites
