Tyria jacobaeae was introduced as a biological control agent to control the noxious weed Jacobea vulgaris. Eventually introduced to the Cascade mountain range of Oregon, T. jacobaeae has been found to feed on Senecio triangularis, a native plant closely related to J. vulgaris. Nosema tyriae is a parasitic fungus under...

The cinnabar moth (Tyria jacobaeae (L.), Lepidoptera: Arctiidae) is an icon in
population ecology and biological control that has recently lost its shine based on evidence
that (1) it is less effective than alternatives (such as the ragwort flea beetle Longitarsus

jacobaea...
Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in...
