In the past, breeding for incorporation of insect pest resistance or tolerance into cultivars for use in integrated pest management schemes in oilseed rape/canola (Brassica napus) production has hardly ever been approached. This has been largely due to the broad availability of insecticides and the complexity of dealing with high-throughput phenotyping of insect performance and plant damage parameters. However, recent changes in the political framework in many countries demand future sustainable crop protection which makes breeding approaches for crop protection as a measure for pest insect control attractive again. At the same time, new camera-based tracking technologies, new knowledge-based genomic technologies and new scientific insights into the ecology of insect-Brassica interactions are becoming available. Here we discuss and prioritise promising breeding strategies and direct and indirect breeding targets, and their time-perspective for future realisation in integrated insect pest protection of oilseed rape. In conclusion, researchers and oilseed rape breeders can nowadays benefit from an array of new technologies which in combination will accelerate the development of improved oilseed rape cultivars with multiple insect pest resistances/tolerances in the near future.
在过去，几乎没有采用将抗虫性或耐受性纳入油菜/芥蓝（甘蓝型油菜）品种的选育方法，以用于综合虫害管理计划。这主要是由于杀虫剂的广泛可用性以及处理昆虫表现和植物损伤参数高通量表型的复杂性。然而，许多国家的政治框架最近发生的变化要求未来可持续的作物保护，这使得作为害虫昆虫控制措施的培育方法再次具有吸引力。与此同时，基于相机的新型跟踪技术、基于知识的基因组新技术以及对昆虫与甘蓝型油菜相互作用生态的新科学认识正在出现。在这里，我们讨论并确定了有前途的选育策略和直接及间接选育目标，以及它们在未来综合防治油菜鳞翅目害虫保护中的实现时间。总之，研究人员和油菜育种者现在可以受益于一系列新技术，这些技术结合起来将加速具有多种鳞翅目害虫抗性/耐受性的改良油菜品种的开发。
