    Erin reports back from a Extension meeting on the impact of the Derecho on agriculture in Iowa.  More details and help in recovering from the Derecho can be found here:

    Matt tries to get our minds off of the Derecho, drought and rising soybean aphid populations with a Fun (?) Insect Trivia question.

    Stay safe.

    Courage,

    (S11:E12): Post-Derecho report, part 1 (also soybean aphid population are increaseing)

    It was a terrible, horrible, no good very bad week in central Iowa.  Erin and I give a summary of the Derecho's impact. We give a brief shout-out to ISU Extension, and Meaghan Anderson's summary of the damage to corn (https://mailchi.mp/4d564a6886f2/aixk6z6qw1-5248549?e=89e709107e). Consider joining Meaghan's newsletter: https://iastate.us10.list-manage.com/subscribe?u=08f91c67b14ea5bf5a26ba3c9&id=dbef152d4f

    We also talk about the recent increase in soybean aphid populations and the occurence of sub-populations that are resistant to pyrethroids. This may result in soybean aphids remaining in fields that were sprayed with insecticide.

    No fun insect trivia this week. It was enough just to clear the yard, fields, etc and get the power back on.

    (S11:E11): Whose gonna win the race- soybean plants or aphids?

    (S11:E11): Whose gonna win the race- soybean plants or aphids?

    Erin and Matt are back after a week off of podcasting to discuss a remarkable sitatution in Iowa. Soybean plants are developing faster than normal, 1-2 weeks ahead of schedule.  Aphid populations are increasing. Are the plants going to out grow the aphids? So what should a farmer do? Erin and Matt discuss the pros and cons of a foliar insecticide application.

    Erin discusses some insects attacking the other crop grown in Iowa (hint: its corn). Corn earworms are causing injury due to the second summer migration.

    Its a drought in the wester half of Iowa and the duo discuss how that may or may not be the cause of more frequent observations of spider mites.

    Finally, Matt has a short FIT-ish question for Erin that she gets right! That's two in a row.

    (S11:E10): Breaking out, in a corn sweat.

    The heat is making field work challenging and podcasting an attractive alternative.

    Erin covers a lot of ground, recapping reports of increasing (though sub-economic) soybean aphid populations, rootworm injury and new additions to the insects found in corn and soybean fields, including skipper sightings in soybeans (https://crops.extension.iastate.edu/blog/erin-hodgson/have-you-spotted-skipper).

    The hot and dry conditions in the western half of the state is making it challnging for corn and soybeans. We've seen this issue in the past, and this article reviews how to address spider mites that may be exacerbated by these weather conditions: https://crops.extension.iastate.edu/cropnews/2018/08/you-%E2%80%9Cmite%E2%80%9D-want-scout-drought-stressed-crops

    Matt highlights some observations from a cannabis farm, in which a Eurasian Hemp Borer was observed on several plants.  A summary of this pests biology, ecology and management can be found in this factsheet from the Colorado State University: https://webdoc.agsci.colostate.edu/hempinsects/PDFs/Eurasian%20hemp%20borer%20September%202018%20rewrite(1).pdf

    On 23 July, 2020, Matt is speaking at a webinar sponsored by the Liberty Prairie Foundation.  He wil talk about how the prairie strips practive in the Conservation Reserve Program (CP-43) can conserve pollinators on farm land. Details about this webinar and others hosted by the Liberty Prairie Foundation can be found here: http://libertyprairie.org/calendar/. Please feel free to join the webinar.

    See you next week and stay safe.

    (S11:E9): Alfalfa caterpillars, not just in alfalfa! All that and more.

    (S11:E9): Alfalfa caterpillars, not just in alfalfa! All that and more.

    Erin breaks it down for us, describing the increasing the number of pest species attacking soybeans in Iowa.  This includes, but not limited to, aflafla caterpillar, soyean gall midge, soybean aphids and why not, Japanese beetles. Matt shares a mythological inspired FIT.

    Erin will be at "Essential Row Crop Managment Summer 2020" Webinar series. This is a joint venture between University of Minnesota Extension and Iowa State University Extension and Outreach, starts next week. This series of short, timely, and topic-specific webinars for farmers, ag professionals, Extension personnel and other interested parties will be held from 1:00 to 1:30 p.m. on July 14, 16, 21, and 23.

    Matt will be featured in a webinar sponsored by the Liberty Prairie Foundation's summer lecturer series:  https://libertyprairiefoundation.salsalabs.org/PrairieStripsBenefitPollinatorsandFarmers/index.html

    Stay safe out there!

    (S11:E8): Its July, and there are more than fireworks in the air.

    (S11:E8): Its July, and there are more than fireworks in the air.

    Erin and Matt talk about the growing community of insects found in soybean and cornfields.  Erin shares updates from her field staff, including observations of several species of lepidoptera that are still in caterpillar form. For more details visit, https://crops.extension.iastate.edu/blog/erin-hodgson/caterpillars-noted-soybean

    She also gives an update on the frequency and growth stage of soybean gall midges.  For more information about the Soybean gall midge, visit https://soybeangallmidge.org/

    Finally, Erin mentions her rootworm trapping network. Details can be found here: https://crops.extension.iastate.edu/blog/ashley-dean-erin-hodgson/new-trapping-network-corn-rootworm

    Matt shares a F.I.T. that was inspired by a 2019 interview of Saturday Night Live cast member Kate McKinnon, https://www.youtube.com/watch?v=63GC6z1RsQQ.

    Don't watch the clip until after you heard the clues, as Kate gives a way the name of the type of insect in her interview.  If you want a hint, names associated with this insect include, but are not limited to: biting, non-biting,  phantom, mountain, meniscus, and dung.
