First emergence of #soybeangallmidge occurred this past week on May 31st at @NebENREEC near Mead, NE. We haven't seen adult emergence at any other sites in the network. Take a look at the checklist on soybeangallmidge.org to see if action is needed and adult emergence updates.

@true_bug We have a few weevils in South Dakota. Just a few though.

The day in review: red seed weevil season is in full swing, pollination studies are HOT, birds and squirrels are jerks.

True armyworm caterpillars spotted in wheat at the SDSU Northeast Research Farm. So far defoliation is minimal, but wheat should be scouted from now until harvest to monitor populations. extension.sdstate.edu/true-armyworm-…

@brentlarson23 @wattnemm Looks like a white grub not a rootworm larva to me.

Found corn rootworm larva for the first time this year in corn on corn field near Wood Lake, MN.

@joel_dejong Hi Joel so far the populations are around Presho, SD but it’s possible that they are more widespread. The weather this week and next will make scouting a little tougher!

@SDSUExt_Insects Thanks Adam. What part of the state? Might be of concern for NW Iowa cover crops too?

Army cutworm caterpillars are active in South Dakota.

Wondered why the winter wheat wasn’t greening up as quick in areas throughout the field. Little bastards are already at it. #cutworms

@Diversified_Ag Are you seeing any wilting associated with the soybean gall midge infestations? Also, here's the scouting recommendations for two-spotted spider mites. extension.sdstate.edu/spider-mites-r…

Zero known history of gall midge before 2021 in any of these fields. Finding them easily today… unfortunately. Did I mention spider mites??? They exploded also.

@clint_weyhrich @AgronomyBrad Unless you were seeing a lot of defoliating insect pressure, my recommendation for the future would be to save your money. Check the thresholds then spray to save money, reduce the chances of a pest population taking off, and prevent insect resistance to AIs.

@AgronomyBrad I haven't seen any feeding on my beans but I put lambda and imidicloroprid on when I sprayed glufosinate about 30 days ago. Putting another round on now while I put on fungicide.

Small isolated field in Pipestone County, but the aphids sure found it. Lots of predators (and if you look close you can see a few mummies).

@AgronomyBrad @DarrenFischer The soybean aphids would be the least of your worries with that setup!

@DarrenFischer Genius!!

The evening temperatures have been pretty low but insect activity in South Dakota is increasing. Army cutworm caterpillars have been observed in alfalfa. extension.sdstate.edu/its-time-scout…

@AgronomyBrad @CHS_Brandon1 How far into the field are you seeing the infestation? Is it adjacent to a field that was soybean last year?

Idk what the record for Gall Midge larvae is... but this field is probably close. @CHS_Brandon1 @SDSUExt_Insects

Check out the latest issue of the SDSU Extension Pest and Crop Newsletter. This particular issue covered a lot of insect pest topics. igrow.cmail19.com/t/ViewEmail/j/…

@Diversified_Ag This isn’t what I meant when I suggested speed scouting soybean...but it looks like you have some alfalfa caterpillars and green cloverworm caterpillars.

If you are ever wondering what insects are feeding on your soybeans, just look at the front of your 4 wheeler!!

@DougAndersonPal @mike_butenhoff Looks like true armyworm.

@mike_butenhoff What’s the name of the worms

This was a corn field a 1 week ago, Damage worms can do to 56 acres in 7 days! My customer said it was a beautiful field on the 5th of July.

Found some soybean aphids this afternoon on the Minnehaha/Moody county line. @SDSUExt_Insects @sdsoybean

Scouting fields on Friday for #westernbeancutworm, and some had 0% egg masses, but I still saw adult moths resting inside whorls. This one is a gravid female, meaning she is plump full of eggs to lay over the weekend. That means we’ll be scouting again on Monday!

Lots of #soybeangallmidge adults emerging from this year’s soybean fields in Saunders County, NE. We don’t have any recommendations for managing adults this late in the season. @erinwhodgson @SWMNpest @SDSUExt_Insects @LaurenBotine @CurtHoffbeck @BobWrightUNL @NebENREC

I'm quite confident this is an isolated case, but damn July 6th is too early for this shit. #soybeans
