Western bean cutworm survey
We continue to track WBC emergence and level after it arrived in Michigan in 2006. The 2012 field season was a low year for moth catch and larval damage, and significant biological control of egg masses (espcially parasitoids) likley contributed to the low level. In 2013, we will be trapping on a limited basis, and conduct an annual egg survey to determine % parasitism and hatch success.

Midwest suction trap network for aphids
Winged aphids, including soybean aphids, are collected weekly from May until October using 20+ ft suction traps. There are five traps in Michigan in Kalamazoo, Monroe, Ingham, Saginaw, and Sanilac counties, and over 40 traps in the Midwest. Data is posted weekly on the NC Region Aphid Suction Trap web site. Michigan traps are hosted by Ned Birkey (MSU Extension, Monroe Co), Paul Horney (MSU Saginaw Valley Research Farm), and Martin Nagelkirk (MSU Extension, Sanilac Co). Dave Voegtlin, University of Illinois, provides aphid identification.
