This project aimed to characterize the spatial and temporal characteristics of white
grub hot spots and evaluate the utility of these areas for making IPM decisions on
golf course turf. The economic costs associated with white grub scouting and several
different white grub management alternatives was also quantified and compared.
Results indicate a potential benefit of using integrated pest management tactics against
white grubs in golf course environments and provide a basis for creating more efficient
white grub scouting and decision making programs. In the long-term, golf course
superintendents armed with the information provided by this research will be equipped
to make informed decisions about white grub management that will allow them to move
away from prophylactic insecticide treatments.
