Potato virus Y (PVY)
- One of the most economically important pathogens of potato
- Numerous strains which cause a variety of symptoms including leaf mottling and crinkling, stunting, veinal necrosis, and tuber necrosis
- Has a very broad host range – capable of infecting plants in many different families
- Spread by the planting of infected tubers and through aphid transmission
- Can be spread from plant to plant in seconds to minutes by many species of aphids, with the green peach aphid (Myzus persicae) generally considered the most effective
- Some important management strategies include: planting of clean seed; use of resistant potato varieties; use of mineral oils to interfere with aphid transmission; use of early planting and vine kill dates to avoid late season spread from high aphid populations

The Oklahoma Brown tarantula – Aphonopelma hentzi
- Found in the grassland areas of southern CO, especially in the La Junta area.
- Males live to be about 8 years, while females can live for over 20 years. Once males mature, they all move about in the fall looking to mate with females, this is usually covered by media as a tarantula migration.
- A female tarantula will dig a burrow and live in it for decades, while males die shortly after reaching maturity.
- This species of tarantula are ambush predators; they use their webs to line their burrows and set trip lines out in front of the burrow’s entrance. When they’re hungry, they will lurk in the entrance and wait for the trip lines to vibrate before grabbing whatever is in front of the burrow. This is usually beetles, grasshoppers, and other spiders.
- A female will lay her eggs in a special ball made of silk called an egg case; a healthy female can have 1,000 babies per egg case and will lay one about every other year. Out of all those babies, only one or two will survive to adulthood.
- A great place to learn more about this species is through the Deep Look episode on this species, filmed at the CSU Bug Zoo, or through the Agricultural Biology fact sheet
