Japanese Beetles Eating Away at Hoosier Trees, Flowers and Crops

Japanese beetles are out in full force, munching away at trees, flowers and crops across southern Indiana. And in two more weeks, they will invade the rest of the state.

These metallic green and bronze beetles are emerging for yet another summer feast on roses, shrubs, flowering fruit trees and deciduous trees such as linden, sassafras, sycamore, Norway, maple, birch and elm.

"Every year these beetles are drawn like magnets to the same trees and bushes in home owners' yards and gardens," said Tim Gibb, Purdue University Extension entomologist. "If beetles are a nuisance now, they will be a problem for many years to come."

Japanese beetles feed on more than 300 different plant varieties, and newly transplanted trees are highly susceptible to damage, Gibb said. Adult beetles also may feed on corn and soybeans, causing serious damage.

Japanese Beetles Emerging in the Rain!
A wet spring and early summer will have little effect on grub damage this year because damage is largely controlled by the weather in August and September. If we have a relatively dry August and September, grub damage may be significant.

The Life Cycle of White Grubs
We constantly get questions about controlling white grubs. The first step to control is understanding the life cycle of the insect. White grubs in Indiana are usually the immature stages of Japanese beetles or masked chafers. These beetles are currently active and will lay eggs in turfgrass throughout July and into August.
