Some argue that introducing a non-native insect to control an invasive plant species is the best solution. What are the potential major risks of this approach that must be considered before making a decision?
Risks include: the insect could become invasive itself, it might prey on native plants, it might not effectively control the target weed, it could disrupt the local food web, lack of natural predators for the introduced insect. (Focus is on identifying criteria for judgment/risks).
