[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.
