Conservation biological control suppresses pests by promoting established rather than inoculative or mass released natural enemies. Research in this approach has expanded rapidly this century but uptake remains limited. Why? Most of the 150 peer reviewed papers reporting field experiments include results on natural enemies and/or pests. Only a minority report effects on crop damage levels or yield, and very few consider economic consequences. This is despite evidence for potential benefits across this full spectrum of response variables. We argue that the limited scope of work to date constrains the development of a compelling evidence base to demonstrate the field effectiveness of conservation biological control, hampering its uptake so encourage researchers to include the assessment of economic impact in future studies of conservation biological control. © 2020 Society of Chemical Industry

在营养级别和经济措施方面，保护性生物防治研究非常不平衡

保护性生物防治通过促进既定的而不是接种或大规模释放的天敌来抑制害虫。这种方法的研究在本世纪迅速发展，但采用率仍然有限。为什么？在150篇同行评议的论文中，大多数报道了田间试验的论文都包括有关天敌和/或害虫的结果。只有少数人报告对作物损害水平或单产的影响，很少考虑经济后果。尽管有证据表明在整个响应变量范围内都有潜在的好处。我们认为，迄今为止有限的工作范围限制了令人信服的证据基础的发展，以证明生物保护自然保护的现场有效性，阻碍其吸收，因此鼓励研究人员在未来的保护性生物防治研究中纳入对经济影响的评估。©2020化学工业协会
