Ladybirds (Coleoptera: Coccinellidae) are not only beautiful insects, they also serve important functions in ecosystems and are important in biological pest control. For over a century they have been used as biocontrol agents of phytophagous pests, such as aphids and whiteflies. Rondoni and colleagues review the success and establishment of introduced ladybirds in biological control programmes. They also consider effects of introducing exotic ladybirds on the native fauna, withHarmonia axyridis (Pallas) in Europe as a well-studied example. This is a state-of-the-art overview of biological and environmental factors that determine the success and risk of ladybirds as biocontrol agents.

瓢虫（鞘翅目：瓢虫科）不仅是美丽的昆虫，它们在生态系统中也发挥着重要的作用，在生物害虫防治方面也很重要。一个多世纪以来，它们一直被用作蚜虫和粉虱等植食性害虫的生物防治剂。Rondoni 及其同事回顾了引入瓢虫在生物控制计划中的成功和建立。他们还考虑了引入外来瓢虫对本地动物群的影响，以欧洲的 Harmonia axyridis (Pallas) 作为一个经过充分研究的例子。这是对决定瓢虫作为生物防治剂的成功和风险的生物和环境因素的最新概述。
