Answer:
Controlling purple loosestrife can be an exhausting and expensive process that may have limited success. Thus, the use of a biological control agent has been a handy tool to reduce the effort needed to considerably reduce the threat of purple loosestrife to our wetlands. Biological controls are animals, bacteria, fungus or viruses that are released into an infestation of an invasive species to consume or infect and kill the invasive species.
Biological controls must be thoroughly and extensively researched to ensure there are no secondary effects of the control, such as another species being killed by the control. Biological controls do not usually eradicate an invasive species, but they provide a level of control that can significantly reduce the species presence, making it either inconsequential or easier to control via other methods.
This blog will explore biological control, invasive species issues, and provide a step-by-step guide to how to responsibly raise and release Galerucella beetles for the control of purple loosestrife.
