In this episode, Matt and Erin talk about upcoming events, pest activity updates and research projects. Erin is organizing a Corn Insects Workshop on July 29. Learn more and register here: http://www.aep.iastate.edu/feel/insect.html. There is a 50-person cap, so register now if you want a space! Erin had several reports of pea aphid in alfalfa, but most farmers decided to cut instead of spray. Learn how to identify aphids in alfalfa here: http://crops.extension.iastate.edu/cropnews/2016/05/aphids-showing-alfalfa. Erin also saw a few aphid mummies in clover and they both experienced honeydew dripping from a tree on campus this week. Matt talked a bit about planting conditions for his wasp and bee projects, noting compaction and crusting in some commercial soybean fields.
As the tagline for the new movie, Popstar, says: Never Stop Never Stopping!
Today, Erin gives a short note to announce the new podcasting widget. It will be located on their Soybean Entomology Lab website, where other resources are available. You can still subscribe to the podcast via iTunes, Stitcher or Pocket Casts. Thanks for listening!
In this episode, Matt and Erin interview the 2016 Gunderson Memorial Seminar speaker, Dr. Ric Bessin. Ric is a professor and extension entomologist at the University of Kentucky. His areas of extension and research interests range from row crops to specialty crops, and has a focus on IPM. Their conversation starts off talking about agriculture in Kentucky compared to Iowa.
He also shares observations about early season pests, like wireworms, and moves to brown marmorated stink bug, an invasive species causing havoc in Kentucky. Ric was also a Peace Corps volunteer before graduate school, and where he spent time beekeeping. He shares an interesting story about using bees to help with pain management.
Matt's a bit under the weather in this episode, but that won't stop his awesome commentary (see connection to Michael Jordan here)! Today, Matt and Erin talk about a new research development with soybean aphid. The entire genome was recently sequenced; see journal paper here). This is only the fourth aphid genome to be sequenced so far. Colleagues, Drs. Brad Coates and Andy Michael, helped generate data for this journal article. Matt explains the reasoning for sequencing the genome of pest species like soybean aphid. Once we have a better understanding of the genetic makeup of a pest, we can try to disrupt it and make them less successful. Then, Erin shares some recent questions coming to her from around Iowa - particularly if snow cover can help insects survive the winter.
In the last episode of season 7, Matt and Erin talk about two new insecticide options for soybean aphid in Iowa. Movento and Sivanto by Bayer CropSciences are products that target fluid-feeding pests, like aphids, and are considered reduced-risk options compared to broad spectrum insecticides. Movento is a Group 23 and Sivanto is a Group 4D. To learn more about these insecticide groups, visit the IRAC website.
Today, Matt and Erin cover a lot of topics. First, Erin summarizes her recent trip to Indianapolis for the 2017 North Central Branch ESA meeting. Lots of interesting papers and posters were presented this week. Also, the first confirmation of soybean aphid in Iowa happened again this week. It is typical to find aphids during early June in vegetative soybean, so listeners shouldn't be too concerned at this time. Other pest activity updates include more black cutworm and armyworm, plus a few bean leaf beetles and slugs. Matt follows up on the slug conversation by highlighting a recent interview with Penn State entomologist, John Tooker. As a follow up to the IRAC discussion a few episodes ago, Erin reminds everyone that the organization puts out a few helpful references on insecticide modes of action and resistance management.
Two events of interest coming up:
Pollinator Fest at Reiman Gardens is on June 24. It's free this year, so bring your family for some fun hands-on activities centered around pollinators.
Today, Matt and Erin cover a wide range of topics. First, there are two entomologists interviewing for ISU president: Sonny Ramaswamy and Wendy Wintersteen. But the conversation is quickly diverted into talking about why entomologists make good leaders. Matt has another F.I.T. that includes a reference to Hogwarts. Tom Saunders named a new parasitoid wasp species after Lucius Malfoy, a character in the Harry Potter series. The new wasp was named Lusius malfoyi. Erin asks Matt about fall nuisance invaders around Ames, including multicolored Asian lady beetles, minute pirate bugs, and brown lacewings. Erin gives a shout-out to an insect-related podcast, Arthropod, from the University of Nebraska-Lincoln. This interesting series goes in-depth on insects and closely related species (e.g., painted lady butterflies and brown recluse spiders). Lastly, they are spreading the word about a fundraiser for BugGuide - help them meet their goal of $15,000!
Today, Matt and Erin bounce around a few topics of insect-related news. The black flies and mosquitoes have been especially aggressive in central Iowa this week. Erin summarizes field crop pest activity in central and southern Iowa, mainly some caterpillar feeding in corn and bean leaf beetle feeding in soybean. Matt's F.I.T. is somewhat random, but eventually ties it together with an insect.
This might be one of the best episodes yet, because Matt and Erin combine aphids with rock and roll. But first Erin gives a state update on pest activity that includes armyworms, leafhoppers, rootworm and bean leaf beetle. There haven't been any reports of soybean aphid in 2018 but immigration is expected soon. Matt is a friend of the FC Bugeaters and shares recent game activity from the midwest. The F.I.T. focused on an insect-themed game show tune and then they transition to a recently published article that hypothesizes AC/DC is noise pollution for insects.
Matt and Erin are back and starting Season 10! Erin kicks off the episode by summarizing current pest activity for 2019. It's been a cool, wet spring and delayed planting will influence early-season pest activity. Specific updates:
- Bean leaf beetle winter mortality was high.
- Seedcorn maggots are flying.
- Alfalfa weevils are active.
- Expected corn cutting dates from black cutworm are approaching.
- Soybean egg hatch is happening, most likely in northern Iowa, where most of the buckthorn is located.
Matt talked about a new F.I.T. (fun insect trivia), where he highlights the mosquito trapping network at ISU. Dr. Ryan Smith coordinated a mosquito and tick surveillance program to learn more about activity and disease incidence around the state every summer. Learn more about his historical data on his website.
Matt also had an opportunity to podcast with group of Iowa Youth who entered an NPR challenge. You can hear the episode where they talk about using insects for food here later this summer!
