Through our work with donors and partners, we are helping to manage the spread of invasive species, a problem that costs the world almost 5% of global gross domestic product or an estimated US$1.4 trillion per year
Millions of the world’s most vulnerable people face problems with invasive weeds, insects, plant diseases and animals, which fundamentally threaten the economic growth supported by sustainable development.
Invasive species disproportionately affect vulnerable communities in poor rural areas, especially in developing countries, which depend on natural resources, healthy ecosystems, trade and tourism for their livelihoods.
Recognising the urgent need for action to protect development and economic growth, we are tackling invasive species around the world. Through a range of projects, knowledge tools and our Action on Invasives programme, we help protect livelihoods and the environment.
We have worked on invasive species for over 100 years, developing practical ways of tackling the biggest threats. Our scientists are world leaders in biocontrol research – an approach that uses invasive species’ natural enemies, like insects, to control their spread.
We produce a range of dedicated knowledge tools on invasive species. These include information on how to prevent the spread of invasive species, how to detect outbreaks and best practice solutions for controlling invasives.

The yellow-legged Asian hornet, Vespa velutina nigrithorax, was first detected in central Europe in 2004 and has since established in many countries on the continent. This hornet is a predator of honey bees and other insects, threatening honey production, pollination services and biodiversity. With Switzerland facing the imminent invasion by the hornet, CABI was commissioned by the Swiss government to help with the preparation for the threat and the control of the first arrivals. This project aims to establish a monitoring system for the early detection of the Asian hornet, determine control strategies and use climate modelling to predict where in Switzerland the insect might settle.
The desert locust, Schistocerca gregaria (Forskal), is arguably the most destructive agricultural pest, globally. During 2019 and 2020, the changing weather created conditions that are favoured by the desert locust for rapid reproduction and migration and led to the pest spreading through the Horn of Africa, East Africa, Arabian Peninsula, South West Asia and West Africa. It is estimated that over 25 million people in Ethiopia, Kenya, Somalia, South Sudan, Uganda and Tanzania will face acute food insecurity in 2020 due to the desert locust plague. This initiative tests the use of drones as a new technology to complement traditional desert locust management measures, including the development of Standard Operating Procedures for optimal use of the technology. The project is initially trialled in Kenya with the potential for scaling to other affected African countries.
Japanese knotweed is a highly invasive weed that impacts severely on native biodiversity and local infrastructure in its introduced range. Whilst chemicals are currently used to control the weed, this approach is costly and unsustainable. Biological control is an alternative method. The damaging leaf-spot fungus, Mycosphaerella polygoni-cuspidati, which attacks the plant in its native range was found not to be suitable as a classical biocontrol agent. However, the pathogen is considered to hold potential as a mycoherbicide. The aim of this project is to undertake proof-of-concept research into a potential mycoherbicide, in collaboration with the private industry.
