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

A 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.
