ABSTRACT

Biological control is widely utilised for the management of invasive alien plants (IAP). With the ever-increasing number of IAPs, it is important to prioritise targets for biocontrol in order to maximise the use of resources and the chances of success. This paper reviewed 12 previous systems developed to prioritise plant targets for biocontrol. The review underpins the selection of attributes and methodologies for the prioritisation of targets for biocontrol in South Africa. All of the previous systems are purpose-built and context-specific, so a new system is required for the South African setting. Previous prioritisation systems were assessed based on the attributes and methodology adopted. The attributes of previous systems were grouped into three sections, being (1) impact/importance of the target plant, (2) likelihood of achieving success, and (3) investment required. Nineteen attributes from previous systems are included in the new system, while nine were excluded due to a requirement for legislation and/or research, or because they conflicted with objectives of the new system in some way. Two methodological approaches were identified for how systems sourced information, either sourcing information through expert knowledge or the use of available literature and data. This information was then applied through either a quantitative or qualitative scoring method. A quantitative scoring method, with information sourced from available resources, was selected as the most appropriate methodology in the context of the new system for South Africa. This review streamlined the development and testing of the South African Biological Control Target Selection system.

摘要

生物控制被广泛用于管理外来入侵植物 (IAP)。随着 IAP 数量的不断增加，重要的是优先考虑生物控制目标，以最大限度地利用资源和成功的机会。本文回顾了之前开发的 12 个系统，这些系统用于优先考虑植物生物防治目标。该审查为南非生物防治目标优先排序的属性和方法选择提供了支持。以前的所有系统都是专门构建的并且特定于上下文，因此南非环境需要一个新系统。以前的优先排序系统是根据所采用的属性和方法进行评估的。先前系统的属性分为三个部分，即（1）目标工厂的影响/重要性，（2）取得成功的可能性，(3) 需要投资。新系统中包含了来自先前系统的 19 个属性，而由于立法和/或研究的要求，或者因为它们在某些方面与新系统的目标相冲突，9 个属性被排除在外。对于系统如何获取信息，确定了两种方法论方法，要么通过专家知识获取信息，要么使用可用的文献和数据。然后通过定量或定性评分方法应用此信息。在南非新系统的背景下，采用从可用资源获取信息的定量评分方法被选为最合适的方法。该审查简化了南非生物控制目标选择系统的开发和测试。新系统中包含了来自先前系统的 19 个属性，而由于立法和/或研究的要求，或者因为它们在某些方面与新系统的目标相冲突，9 个属性被排除在外。对于系统如何获取信息，确定了两种方法论方法，要么通过专家知识获取信息，要么使用可用的文献和数据。然后通过定量或定性评分方法应用此信息。在南非新系统的背景下，采用从可用资源获取信息的定量评分方法被选为最合适的方法。该审查简化了南非生物控制目标选择系统的开发和测试。新系统中包含了来自先前系统的 19 个属性，而由于立法和/或研究的要求，或者因为它们在某些方面与新系统的目标相冲突，9 个属性被排除在外。对于系统如何获取信息，确定了两种方法论方法，要么通过专家知识获取信息，要么使用可用的文献和数据。然后通过定量或定性评分方法应用此信息。在南非新系统的背景下，采用从可用资源获取信息的定量评分方法被选为最合适的方法。该审查简化了南非生物控制目标选择系统的开发和测试。
