Aphids establish a foothold

Show: 
Soybean Pest Podcast
Season: 
3
Episode: 
3
Description: 

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.

Description: 

On a special episode of the podcast, we are visited by Dr. Donald Lewis who asks; "Will the soybean aphid outbreak bring more lady beetles". This hard-hitting question is answered, to the best of their ability by Matt and Erin. 
The lady beetle in question, is the multi-colored Asian lady beetle, Harmonia axyridis. This is a beneficial insect in soybean fields but a pest in our homes.

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

Show: 
Soybean Pest Podcast
Season: 
6
Episode: 
7
Description: 

“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.

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/.
