Description: 

Dr. Mary Gardiner, assistant professor at the Ohio State University, visited ISU and gave a seminar about her research on the ladybeetles.   Ladybeetles can play a positive role by feeding on pest like the soybean aphid.  Mary's research is focused on the exotic multi-colored asian ladybeetle. This species is a voracious predator of soybean aphids, but is also a pest in our homes and to grape growers.  Mary is documenting the role landscape plays in the establishment of this species as part of her Buckeye Lady Beetle Blitz.  To learn more about Mary's work visit http://ladybeetles.osu.edu/default.asp

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.
