Pinewood Nematode (PWN)
- Bursaphelenchus xylophilus is the nematode that causes pine wilt disease.
- Pinewood nematode is transmitted by the pine sawyer beetle (Monochamus spp).
- Needles turn grey to brown in the fall and stay attached to the tree through the winter.
- Infection begins in June or July and is more common when high early summer temperatures are present.
- Pines that are not native to North America are more susceptible to PWN.
- Symptoms very depending on the species of the pine.
- Wilting is caused by damage to the vascular tissue inflicted by the nematode.
- Pinewood Nematodes overwinter in their insect vector.

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
