In the eastern United States, exotic species of white grubs have replaced native species in home lawns. Japanese beetle, European chafer, and oriental beetle are capable of causing extensive turf loss at densities of 30 or more per 0.1 m2. However, healthy lawns can usually tolerate 20 grubs per 0.1 m2 without any visible symptoms of infestation. Animal foraging is an exception, and lower levels of grubs are desirable to avoid skunks and racoons. Therefore, the goal is to manage home lawns in such a way that grubs are kept to densities below 10 per 0.1 m2 . Recent studies show that this can be accomplished with with good cultural practices that enhance predators, parasites and pathogens of white grubs. Results of recent research on the impact of irrigation practices on European chafer, and turf species and cultivar tolerance to grubs will be presented. These studies suggest that grub damage to lawns can be almost entirely eliminated by growing a tolerant type of turf with good irrigation, fertility and mowing practices.
