Insects

When you encounter an insect in a surprising place it can be alarming, particularly if you’re one of the many people who has an uncomfortable relationship with insects. Entomologist Zach Schumm of Iowa State University joins this Horticulture Day to give us the tools we need to decide if an insect is a pest or something we should leave in peace. Extension horticulture specialist Aaron Steil also joins to answer listeners' horticulture questions.
  • When plants start growing and insects start buzzing, plant diseases aren't far behind. There's no way to protect your garden from everything that can go wrong, but there are things you can do to prevent some common diseases. Chelsea Harbach of the Plant and Insect Diagnostic Clinic at Iowa State University joins to discuss disease prevention.
  • When temperatures drop in the fall, suddenly the outdoors becomes insect-free. That doesn’t feel like much of a mystery. But when temperatures rise in the spring and suddenly insects emerge, it raises questions, like how do these tiny creatures survive in subzero conditions? Entomologist Laura Iles demystifies this phenomenon. Later, horticulturist Aaron Steil joins the conversation to answer listeners' questions.
