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).
Drs. Hodgson and O'Neal return with weekly updates on the insect pests attacking soybeans. This week we discuss the first reports of soybean aphids in Iowa, the growing risk for spider mite outbreaks, and an alarming change in the emergence of Japanese beetles.
June is often a quiet month for insect pests but not this year as the Japanese beetle has emerged 2 to 3 weeks earlier then usual. So even though soybean aphids are uncommon right now, farmers may want to scout for this pest. We discuss what to look for and what the impact could be. To meet with Dr. Hodgson, consider joining her at the Crop Management Clinic (11-12 July) at FEEL. Visit this site for more information http://www.aep.iastate.edu/feel/cmc.html
Its Friday the 13th and farmers have much to worry about. But despite the record breaking temperatures and drought, there is some good news. We discuss the lack of soybean aphids throughout most of Iowa. However, there are other insect pests that growers should be scouting, including japanese beetles and spider mites. For more info about insects this summer, see Dr. Hodgson's blog (http://iowabuglife.blogspot.com).
Erin and Matt are back from a skipping a week. Erin shares a observations from around the state of a several different insect pest sightings, including japanese beetles, thistle caterpillars, and soybean aphids. This includes a discussion of Brian Lange's discovery of soybean aphids in north east Iowa. Erin also shares a first! Below is a link to the longer article about scouting for corn rootworm larvae.
Matt's been writing grants and a little out of it, but he took some time to challenge Erin and our listener with a Fun Insect Trivia. (Hint: its an insect).
Erin and Matt make it back for a second episode. There is a lot of soybean aphid talk in this episode, maybe, maybe too much talk. For a summary of some of that talk, check out this link (https://crops.extension.iastate.edu/blog/ashley-dean-erin-hodgson/first-...).
If you get through the first 15 minutes and are still awake there is another 12 minutes about the following:
- Pea aphids on alfalfa in northern Iowa, may be insecticide resistant.
- Japanese beetle adults have emerged, look to them feeding on corn and soybean. Erin notes that the defoliation on younger soybeans is not 'more bad' than defoliation on older soybeans, it just looks worse because the beans are so small.
- Outside of crop pests, Erin shares a finding of 'kissing bugs' in Nebraska. This is a vector of Chagas disease, which can be lethal. https://dhhs.ne.gov/Pages/Kissing-Bugs-and-Chagas-Disease-Parasite-Detec...
- Matt gives Erin a FIT that involves this picture (what is the insect, listen to the podcast to find out).
- Erin is doing field days throughout the northern part of the state and at FEEL in central Iowa. Check her twitter account for details.
- Matt and many others are sharing their interests, research some swag at the Pollinator Fest at Reiman gardens: https://www.reimangardens.com/event/pollinator-fest-7/
