Japanese
Beetles Eating Away at Hoosier Trees, Flowers and Crops

Purdue
University Extension entomologist Tim Gibb expects to see
a heavy infestation of Japanese beetles in Indiana this summer.
The beetles feed on more than 300 different plant varieties,
making them difficult to control.

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.
