Arthro-Pod EP 80: Chagas disease and kissing bugs

Tune in today to hear the Arthro-Pod gang discuss Chagas disease and kissing bugs. All the hosts have had questions asked of them about this disease and the insect that can help vector the causal parasite. There are lots of stories out there about the dangers but what is the truth about Chagas in much of the US? We'll cover the parasite, the disease, and kissing bugs like the eastern bloodsucking conenose in this episode!

Show notes

Disease: Chagas disease 

Parasite: Trypanosoma cruzi 

Reservoirs: Mammals 

Vectors: Triatomine bugs or kissing bugs  

Reduviidae are a family otherwise known as assassin bugs that are Hemipterans. They have three segmented beak used to stab prey, which are mostly insects. According to Bug Guide, there are 195 species, 55 genera including wheel bug, jagged ambush bug, four spurred assassin bug (Zelus), masked hunter, and Sinea species (no common name)  

Commonly misidentified non-reduviids: Western conifer seed bug, squash bugs,

Arthro-Pod EP 79: What Goes Up Must Come Down- Insect Populations


As Extension professionals, the Arthro-Pod gang often gets asked questions about where a certain insect has disappeared to. It's a tough question to answer because there are so many factors that can impact insect populations. Today we're going to try and unpack some of those factors and talk about why you might be noticing fewer cicadas or why there was suddenly an explosion of butterflies in your area. Tune in!

Arthro-Pod EP 78: Insecticide Resistance with Caleb Hubbard



On today's episode of Arthro-Pod, the gang meets with Caleb Hubbard of the University of California Riverside. Caleb is a veterinary entomologist that works with house flies that can cause issues with dairy farms. These flies can be tough to control but also complicate things by becoming resistant to the insecticides we use against them. 

Tune in to learn about what insecticide resistance is, how it develops, and how researchers try to figure out ways to study it. Also, we learn a recipe for maggot food that sounds pretty yummy.

Arthro-Pod EP 77: All About Galls with Denise Montelongo



Hey everyone, Michael here. I'm excited to share an interview I recorded with Denise Montelongo about gall wasps and her work on them at Penn State. We talked about what a gall is, what kind of organisms make galls, cynipid gall wasps, and a whole lot more.


You can follow Denise's work through the Frost Museum on Twitter @FrostMuseum and the web; you can also sign up for the Museum's newsletter.

Arthro-Pod EP 76: What Bugs Bug the Entomologists?



Usually, the Arthro-Pod crew is all about tying to convince people that insects are cool and to be appreciated. However, they are only human and even they have some insects that they have convoluted pasts with. Some of them they may have come around on but others... well maybe it's best they stay separated! Tune in to hear each host's story!

Arthro-Pod EP 75: The Rise and Fall of DDT Part 2


Welcome back to Arthro-Pod! Today is part two of our deep dive into the history of DDT, a long and convoluted story that has lots of effects on us today. This portion of the story is about the long fall that DDT had, beginning with the publication of "Silent Spring" by Rachel Carson and ending with the creation of the Environmental Protection Agency in 1970. We talk about the way people viewed Rachel Carson and her work, what the problem is with believing in a "silver bullet", and how DDT may have helped politicize environmentalism.

If you enjoyed the show, the majority of the research for it came from David Kinkela's book "DDT and The American Century". It's highly recommended if you want to see more of the primary sources and the inspiration for a lot of our discussion.

Arthro-Pod Special Edition: What the heck is a "murder hornet"?



If you have been watching the news lately, you have undoubtedly heard the phrase "murder hornet" being thrown around. There’s a lot of fear-mongering and sensationalism out there. We’re all stressed out and anything nicknamed a “murder hornet” can’t be good.
The Arthro-Pod gang is here with a special podcast episode to tell you it will be okay and there is little/no chance of you being murdered by one of these hornets. If you have a life-threatening allergy to bees/wasp venom, and even if you don’t, be aware of your surroundings and avoid disturbing hives or nests. Even the cutest, most helpful honey bee will sting you of she thinks the colony is in danger.
We are including some helpful resources here from reliable sources if you are interested in learning more about the Asian giant hornet, Vespa mandarinia. But please stop calling it the “murder hornet”. Entomologists do not and have never referred to them as such.
Bottom line: Chill don’t kill.
