Blacklight captures of stink bugs in Maryland reaching hundreds per night, 5 to 10 fold greater than this time last year, and exceeding peak values of last year.

Galen Dively from the Unviersity of Maryland reports that captures of brown marmorated stink bug adults in blacklights have skyrocketed to hundreds per night in 4 locations covering the state of Maryland.  For example, a 2-night capture was 866, compared to about 20-30 per night at this time last year.  Maryland sites have already exceeded the peak captures from last year, which occurred in mid August last year.

These are summer adults.  They will be moving into crops, feeding on many crop species.  They will feed on fruit that are ripening.  Each feeding puncture can cause damage.

If you have not already started, scout NOW for Brown Marmorated Stink Bug.  I suspect Pennsylvania populations are a bit behind Maryland, but not far behind, and insect develop fast in warm weather.
