2011 Yellow Sticky Trap Project
• 7th year of tracking populations of adult western
corn rootworm (WCR) beetle in soybean fields of
western IL
• Variant WCR beetle lays eggs in soybean field
which allows larvae that hatch the following year
to feed on corn roots in a C-SB rotation field
• Variant WCR beetle has been found in other
areas of IL in past
• Monitoring for variant CRW to determine if
necessary to protect against pest in C-SB rotation
in western IL
