Brown Marmorated Stink Bug Populations Patchy but Some Local
Populations are Large Posted: August 7, 2012 I found stink bugs,
but one thing became quite clear: stink bugs are present and
very active, but they are not everywhere. The picture that
emerged was that stink bugs can be found in most corn and
soybean fields in low numbers, but it is those fields that
border the woods where populations look to be the strongest. For
example, I found a few corn and soybean fields near New Danville
that had particularly large populations. These fields had woods
all along one side of the fields and stink bugs populations were
the largest by this wood line. The soybean fields were
definitely over the economic threshold (2.5 stink bugs per 15
sweeps in narrow row beans, 3.5 stink bugs per 15 sweeps in wide
row beans), but populations were only on the edge, so I would
have recommended a border treatment just along that edge of the
field adjacent to the woods. Because stink bugs are not
everywhere, scouting will be the key t
