Drs. Matt O’Neal and Erin Hodgson created a podcast to promote IPM concepts, like identification, sampling, economic thresholds, and insecticide efficacy. They also talk about updates on invasive pests and regulatory news, and translate new research relative to insects in agriculture.

Soybean Pest Podcast
Season: 
13
Episode: 
6
Description: 

It's a low-key episode that features new intro and outro-music and a new pest noted in our round up (grasshoppers).

Erin's had a long week talking about corn rootworms. We recap the current insect species occuring in soybean fields (grasshoppers, Japanese beetles, soybean aphids, a mix of caterpillars). Some pests are no longer present on the plants as the second generation is developing as immature stages in the soil. These are gall midges and bean leaf beetles. Matt tries to bring her spirits up with two trivia question. The first is a bit silly, noting the music videos on youtube that have been viewed over one billion times. The second question is a FIT that Erin gets immediately. Erin's on a roll.

see you next week, and as always, consider scouting your fields.

(S3:E10): Bringing it home: wrapping up a season of aphids in soybeans

08/30/2011

As soybeans reach the late reproductive stages the need to manage aphids decreases. However, aphids persist in soybean fields around the midwest. We discuss a couple factors that should be considered when applying insecticides this late in the year. Also, we re-count the spread of Japanese beetles in Iowa as a new herbivore of soybeans.

(S3:E9): Rounding third: covering the bases with late season aphid management advice

08/11/2011

The growing season is coming to an end and aphids still persist in some areas.  We discuss how insecticides may cause problems with spider mites, especially with the use of pyrethroid-based insecticides.  Also look for updates regarding bean leaf beetle threshold calculator in the ICM newsletter next week. Thanks to Mike McCarville.

(S3:E8): Pull the trigger?

08/01/2011

Aphid populations continue to increase in Iowa. We discuss their trajectory and when/if insecticides will be needed. Also, new publications from Iowa State University are available for the soybean aphid and the brown marmorated stink bug. To purchase the id guide for stink bugs or the new soybean aphid field guide visit the ISU extension publication store (www.extension.iastate.edu/store). To learn where the brown marmorated stink bug is in Iowa visit www.ncipmpipe.org. 

(S3:E7): Tora tora tora

07/26/2011

Soybean aphid populations reach threshold in Iowa and japanese beetles are becoming an increasing problem for both soybean and corn. In this episode we discuss both of these pests and the need to scout now to determine the need for an insecticide.  To learn more about Japanese beetles see Dr. Hodgson's latest article in the Integrated Crop Management newsletter (http://www.extension.iastate.edu/CropNews/2011/0722hodgson.htm).

(S3:E6): When to spray for aphids

07/11/2011

We discuss the likelihood that aphid outbreaks will occur and when to spray aphid populations. Some agri-businesses are suggesting that aphids be sprayed when populations are lower than 250 aphids per plant. We discuss the value of such lower thresholds, as well as ways to detect other invasive insect pests of soybeans.

(S3:E5): Aphid populations increase! No lie.

07/07/2011

We share reports of aphid outbreaks in soybeans in MN. Numbers are up in Iowa. Also, have you noticed big, metallic green beetles? Japanese beetles are out in Iowa.

(S3:E4): Soybean aphids remain at low levels

06/29/2011

Drs. Matt O'Neal and Erin Hodgson discuss current soybean aphid activity around Iowa and the region. Numbers are remaining low with some regions declining in density. They also discuss upcoming field tours (available at www.aep.iastate.edu).

(S3:E3): Aphids establish a foothold

06/20/2011

Drs. O'Neal and Hodgson summarize reports from around the midwest and Iowa about the soybean aphid. Despite the lack of aphids in the fall, evidence so far is that they survived and are beginning to build up in the northern parts of Iowa. Numbers are still very low and do not require insecticides, but we compare 2011 to previous growing season.

(S3:E2): Soybean aphids found on soybeans

06/14/2011

Soybean aphids have been found on soybeans. We discuss what this might mean for management. We also report on yet another invasive insect pest of soybeans that has been found in the US, the kudzu bug.

(S3:E1): First soybean aphid podcast of 2011!

05/27/2011

Drs O'Neal and Hodgson are back for the 3rd year of the soybean aphid podcast. We review the status of aphids on buckthorn, introduce a new buckthorn project (buckthornwatch.org) and talk about the new invasive pest of soybeans, the brown marmorated stink bug, that has been found in Iowa.
