Brown Marmorated Stinkbug and Kudzu Bug Update

Posted on by

Both the brown marmorated stinkbug and kudzu bug continue to expand their territories.  Below is the latest update of this expansion.Kudzu Bug 080913

BMSB 080913A few fields have needed treatment.  We’ve been successful with edge of field treatments with the brown marmorated stinkbug, as they tend not to move into the middle of the fields.  Hopefully, this IPM strategy will continue to remain effective.

For the kudzu bug, the threshold is 1 kudzu bug nymph per sweep.  So, to trigger a spray, you’ll need to average 15 nymphs per 15 sweep sample.  Also keep in mind that insecticides vary in their effectiveness.  See the chart below for the most effective products.  Products highlighted in pink are recommended.

Corn earworm AVT results, BMSB and Kudzu bug update….nearing the end (Dr. Ames Herbert)

Posted on by

Our final batch of corn earworm moths showed only 26% survivorship, down from last week. This season results showed a 37% survival rate for the seasonal total which exceeds all previous years. We are now up to 33 counties where brown marmorated stink bugs were/are present in soybean fields. Most are at pretty low levels compared with last year, but they are much more widespread. This week n some have been found in soybean fields in north central North Carolina. We are taking as much data as we can to help with answers for next season. And, the first kudzu bug nymphs were found in Charlotte County. We are nearing the end of this season in terms of insect pests and advisories…a long summer for sure.
