Western Bean Cutworm 2010 Trap Results for the Great Lakes Region

 

 

 

 

 

 

Facts about WBC Trapping in 2010:

1.   1084 WBC traps were monitored in the Great Lakes Region in 2010.

2.   200,747 moths were captured in the region; a significant increase from 2009.

3.  Thornloe Ontario (Timiskaming region) captured the most northern moths collected on record.

4.  Moths are being captured as far east as Long Island, New York and Montmagney, Quebec

5.  The average number of moths accumulated per trap in the GLR was 185.  Michigan averaged 402 moths per trap, Indiana averaged 234 while Ontario averaged 110 moths per trap.

6.  Peak flight occured during the weeks of July 5th for Indiana and Ohio, July 19th for Michigan and Pennsylvania, July 26th for Ontario and Quebec and August 1st for New York.  The Timiskaming region traps in Ontario peaked during the week of July 12th indicating that these moths were blown in via storm fronts.

7.  The number of moths captured at each trap site does not strongly relate to infestation levels and feeding damage found in the adjacent field.  However, traps do help determine the presence of moths and when peak moth flight takes place (which indicates when peak egg laying and scouting needs to take place).

Trapping will continue in 2011.  If you are interested in participating in the Ontario trap network, please email us at:  wbctrapnetwork@gmail.com.
