Field Crops Pests - Illinois Trapping Network

Posted by Angie Peltier - Insects

Agricultural professionals throughout the state including University of Illinois Extension Educators are working alongside Kelly Estes of the Illinois Natural History Survey to survey agricultural pests.

Through a network of traps around the state, these folks are working to get snapshots of population levels of major field crops pests throughout the 2013 growing season. These traps use sex hormones called pheromones to ultimately lure insects to their death so that trappers can identify and count them.

Along with the more typical pests such as the corn earworm, European corn borer, fall and true armyworms and Western bean cutworm, field crops pest survey participants are also trapping some recent invasive arrivals to the state.

Efforts are underway this year to gather information about the spread and population levels of the brown marmorated stink bug. This invasive insect pest and voracious feeder was first confirmed in Cook County in 2010 and has moved West and South to be found in nine counties in 2012, including in addition to Cook, Kane, McLean, Champaign, Du Page, Vermillion, Whiteside, Madison and Morgan Counties. Dr. Mike Gray, Field Crops Extension Entomology Specialist with the University of Illinois, recently wrote a Bulletin article about the brown marmorated stink bug.

Each time a member of the Illinois and Iowa field crops pest survey check his or her traps the data is uploaded to the Iowa State University IPM Pipe webpage (Figure). The University of Illinois' Northwestern Illinois Agricultural Research and Demonstration Center in Monmouth is one trapping location (Figure).

Detailed information about 2013 trap catches can be found on the webpages for the individual pests:
