Let’s Celebrate Native Plant Month (April 2025)
All year long, we give you tips and tricks to fight the weeds and pests that bug us. But what about the native plants? The Indian paintbrush, western coneflower, rocky mountain maple, and so many more. There are over 1,200+ native plant species in Teton County, each working in perfect harmony as a vital part of our ecosystem. This month, we’re highlighting a handful of native plants and their contributions to our environment.
Pesticide Resistance in Mosquitoes
Teton County Weed and Pest District’s Entomologist, Mikenna Smith, together with scientific staff from Valent Biosciences will be conducting a mosquito “field cage trial” this month. Field cage trials are large scale, field experiments where mosquitoes are placed in cages that are strategically placed in the path of a truck mounted ultra-low volume adulticide spray drift. This is the most “real world” experiment that can be conducted to determine if certain pesticides can kill the caged mosquitoes.
Weed of the Month: Rush Skeletonweed
Rush Skeletonweed (Chondrilla juncea) is a member of the Sunflower (Asteraceae) family, but unlike many of the native plants in the sunflower family, skeletonweed is an invasive, noxious weed in Teton Valley. Also commonly called hogbite, gum succory, or devil’s grass, skeletonweed originates in Europe, Asia, and Northern Africa but has spread to many western united states, including Wyoming, Idaho, and Montana.
