Plant-insect interactions and management options for Verbascum thapsus L. in Colorado
In the field of invasion biology, understanding the ecology of a species goes hand and hand with understanding management options. Common mullein (Verbascum thapsus L.) is a non-native plant introduced to North America from Europe in the 1700s. It has naturalized and spread throughout North America, with populations establishing after disturbance. Through a series of field experiments, I tested the effect of insect herbivory on the growth of V. thapsus in Colorado and also investigated management options for the reproductive stage of this biennial plant. Verbascum thapsus, while widespread, is ...
