Aphids, now! Aug 06, 2015

Show notes

In this podcast, Matt and Erin talk about recent aphid developments in northern Iowa and southern Minnesota. Soybean aphid numbers are steadily climbing and aphids in corn are making a rare appearance this year. Foliar insecticides are starting to happen to protect yield. Also, Matt recently attended a USDA Corn Climate Change grant meeting and summarizes recent applied and modeling data for future corn production.

Rainy days and Mondays (and aphids, mites and caterpillars) always get me down Jul 27, 2015

Show notes

“Hanging around, nothing to do but frown, Rainy days and Mondays always get me down.” Karen Carpenter sang about this deadly combination and it’s effect on her emotions. Now, Matt and Erin pile on with a list of insect pests that are active in the state of Iowa. Thankfully, it is not all bad news as we review the biology and pest status of spider mites, soybean aphids and a mix of caterpillar species. We discuss how the weather can help determine if a spider mite outbreak is likely and some tips for dealing with one if it occurs. Matt reveals an upcoming gig in which he will speak at a “Conservation Biological Control Short Course” hosted by the Xerces Society for invertebrate conservation. This all-day event is on 21 August at the ISU Field Extension Education Lab. Email us your questions at oneal@iastate.edu and ewh@iastate.edu.

Soybean aphids picking up steam in Iowa Jul 21, 2015

Show notes

Today, Matt and Erin discuss recent soybean pest activity. Of special note, soybean aphids can be more easily found in northern Iowa and scouting fields is highly recommended. Also, green cloverworm is making a special appearance in a few fields. Matt wraps up the podcast by sharing a research update that involves collecting pollen from honey bees to see where they are feeding.

Scout for what? Do it now! Jul 15, 2015

Show notes

Today, Matt and Erin talk about an old pest that is new again. European corn borer is making a comeback in some non Bt-corn. Identification and management are important for timely foliar insecticide applications. Also, Erin saw a small plot with increasing soybean aphid populations - it was also noted in other research plots compared to last week. Lastly, they talk about the potential usefulness of UAVs for making management decisions in field crops. The link Matt mentioned: http://n.pr/1GjpPBx/.

Back together again! Jul 07, 2015

Show notes

Today, Matt is back from vacation and talks with Erin about the latest insect activity in Iowa. Soybean aphids can be found in northern Iowa, but at very low numbers. Japanese beetles are feeding in corn and soybean in central counties, and a mixture of caterpillars are feeding in soybean.

Aphids and green cloverworms show up Jun 23, 2015

Show notes

Matt is on vacation, but the show must go on! Erin talks about recent soybean pest activity in Iowa, including the beginning of soybean aphid sightings in northern counties. Also, some are seeing green cloverworm starting to defoliate plants. Both are at sub-economic levels but continue to scout to make timely treatment decisions in 2015.

Apres le deluge, moi (and by moi, I mean the soybean aphid podcast) Jun 17, 2015

Show notes

“Apres moi, le deluge” is legendary quote from King Louis XV of France. Allegedly he said this with regard to what would happen to France after his death; After me, the flood. 15 years after a reign that saw the loss of wars, territory etc., the French Revolution broke out.
Today on the soybean aphid podcast, we turn this title around (after the rains, us) to discuss the consequences of the June rains that have dropped as much as 6 inches in a 72 hour period. Unlike the terrible decisions of King Louis, these rains can have a benefit to farms by limiting the impact of some pests, especially those in the soil. However, the rains have made it difficult to get into fields for herbicide applications.
We discuss the rain, its impact on pests, and the upcoming Pollinator Festival at Rieman Gardens in Ames this Saturday June, 20.
Also, help us come up with a new name for out podcast. Send your suggestions to Matt at oneal at iastate.edu and/or Erin at ewh at iastate.edu.

Armyworms: not just a corn pest Jun 10, 2015

Show notes

Today, Matt and Erin recap current soybean planting progress in Iowa. They also talk about recent armyworm activity in soybean and considerations for management. Finally, the podcast wraps up with a quick summary of a symposium organized for neonicotinoid seed treatments in field crops from last week.

Live from the Lil' Apple! Part 2 Jun 03, 2015

Show notes

This record-breaking podcast is the second of the day for Erin and Matt. We interview Dr. Jen White from the University of Kentucky to better understand how endosymbionts interact and influence insects, and ultimately how it can help with pest management.

Live from the Lil' Apple! Part 1 Jun 02, 2015

Show notes

In this episode, Matt and Erin podcast from Manhattan, KS to share highlights from the NCB-ESA meeting. We talk with Alice Vossbrinck, OSU graduate student, about her lady beetle study in the agricultural landscape.
