Classical biological control (CBC), the reunification of a pest with its natural enemies from its area of origin, can be a sustainable, long-term and cost-effective way of controlling invasive plants. However, non-target impacts of biological control agents cause significant concerns. To prevent non-target effects, rigorous host-specificity testing is undertaken before biological control agents can be introduced. Willows (Salix spp.) have been widely introduced in Australia where they have become important weeds, due to their high invasiveness and detrimental impacts on waterways and riparian zones. A natural enemy of willows, the willow sawfly Nematus oligospilus, has been inadvertently int..View full abstract
