LOTS OF BEETLES = LOTS OF GRUBS??? PDF Print E-mail
At the recent OTF Regional Seminar (July 14, 2008 at the Sylvania Country Club, Sylvania, Ohio), JAPANESE BEETLE (Popilla japonica) was a hot topic. The beetle has been emerging in large numbers in some areas of the state and has been emerging for a couple of weeks. A big problem that may be in our future from these large populations of adults is very large populations of new white grubs. A factor that is going to contribute to the success of these beetles to produce large populations of white grubs is the current soil moisture conditions. Soil moisture levels are high at the current time, which will make it easier for female Japanese beetle adults to find suitable oviposition sites in which numerous of their eggs will hatch successfully.

Turf managers need to consider having to treat many more acres of turf for white grubs than they have in the past several years. A special note to golf course superintendents, your roughs and out-of-bounds areas may suffer greatly from this new batch of white grubs. All of these areas are maintaining high soil moisture contents, making them very susceptible to attack. If these areas are not dealt with now, the raccoons and skunks will tell us with their diggings if these predictions come true.
