Classical biological control (also called importation biological control) of weeds has a remarkable track record for efficiency and safety, but further improvement is still needed, particularly to account for potential evolutionary changes after release. Here, we discuss the increasing yet limited evidence of post-introduction evolution and describe approaches to predict evolutionary change. Recent advances include using experimental evolution studies over several generations that combine -omics tools with behavioral bioassays. This novel approach in weed biocontrol is well suited to explore the potential for rapid evolutionary change in real-time and thus can be used to estimate more accurately potential benefits and risks of agents before their importation. We outline this approach with a chrysomelid beetle used to control invasive common ragweed.
经典的杂草生物防治（也称为引种生物防治）在效率和安全性方面有着显著的记录，但仍需要进一步改进，特别是要考虑到释放后的潜在进化变化。在这里，我们讨论了越来越多但有限的引入后进化的证据，并描述了预测进化变化的方法。最近的进展包括使用结合了组学工具和行为生物测定的几代实验进化研究。这种杂草生物防治的新方法非常适合实时探索快速进化的潜力，因此可以更准确地估计引入前的生物防治剂的潜在效益和风险。我们用一种用于控制入侵普通豚草的金龟子为例来说明这种方法。
