[Dr. Scott Akin standing in a field] My name is Scott Akin, I'm Extension and Research Entomologist with the
University of Arkansas Cooperative Extension Service. [Picture of a redbanded
stink bug] One of the things I wanted
to talk about today in particular was the Redbanded stink bug. This is a pest
that a lot of folks say "well why do I need to worry about this pest?"
[Dr. Scot Akin] Well we
believe we have some data that indicates that this pest may be more damaging on
a per insect basis. And while not necessarily that much harder to kill than our
more common Green and Southern Green stink bugs but is also, it tends to come
back into a field a little bit quicker.
[Picture showing a Redbanded stink bug and a Redshouldered stink bug] Well there are two
stink bugs, a Redshouldered and a Redbanded stink bug. The Redshouldered stink
bug is the stink bug we've had here for a while. It's not to
believed to be as damaging and it doesn't show up in near the number than the Redbanded
stink bug does. [Picture showing the development stages of the Redbanded stink
bug and the Redshouldered stink bug] They're both relatively small, about half to two thirds
the size of our Green and Southern Green stink bugs that we have. [Dr. Scot
Akin] They both have
a lot of times a red strip across the shoulders, sometimes they don't have that.
[Picture of the underside of a Redbanded stink bug with an arrow pointing to the
spine.] But the Redbanded stink bug has a spine on the ventral surface of the abdomen. If
you can't see the spine for some reason, which is lack of a hand lens or
sometimes it's just hard to see on that adult, [Dr. Scot Akin] sometimes you just look at the
general shape, it's a little bit more rounded, a little bit more slender than
our Redshouldered stink bug but it's important to make sure that we know when we
have this pest and keep those intervals, scouting intervals tightened up [video
showing Dr. Akin sweeping soybean field with a net to scout for pests] simply
because the fact that it may not be that hard to kill right away it will
definitely come back into the field.
[Dr. Scot Akin] Some of the insecticides that have tended to work well for this pest,
sometimes it varies certain times of the year. Some of the bithenfrin products
have seemed to work well, particularly at the higher rates. One to twenty-five
or one to twenty. Indigo seems to be a fairly good product that's worked against
this pest. And a lot of times mixtures of acephate, either higher rates of
acephate or mixtures of acephate and pyrethroid has also tended to work fairly
well.
