Aggressive tracking strategy
"It's more of a list of what it doesn't eat than what it does feed on," said Vaughn Walton, an entomologist at OSU. "Identifying where the bug is found is an ongoing effort. Unfortunately, it has been detected in many of Oregon’s major agricultural areas and the populations are increasing. It looks like it could be a problem soon in some areas based on populations we found in 2012."
OSU researchers are using this field data to plot an even more aggressive tracking strategy for 2013. In the meantime, Oregonians can assist the effort by reporting sightings.
"A lot of the finds we’ve made the past few seasons are because of the public chipping in,” said Nik Wiman, a postdoctoral scientist at OSU's research center in Hermiston, who is studying the insect. “Without it, we would not have as good a picture of how the bug has distributed through the state.”
In the winter, the brown marmorated stink bug seeks shelter indoors, often in attics, garages and dark, moist places. It can be confused with other insects, so the OSU Extension Service has published a two-page guide for the public on how to distinguish it from look-alikes at bit.ly/102dyIw. The document is also in Spanish at bit.ly/S9oHbB. More information on the bug is at bit.ly/Va0m7N.
OSU is one of 11 institutions researching the brown marmorated stink bug in an effort funded by the U.S. Department of Agriculture, the Oregon Hazelnut Commission and the Oregon Wine Board. OSU graduate student Chris Hedstrom has also contributed to the project.
