Earlier this month, CABI warned of the impending rapid spread of fall armyworm across Asia, following its arrival in India. Since then, news of the crop-destroying pest’s invasion has been hitting headlines across the globe.
The damage that invasive species can cause to the environment and the economy are well known, but impacts on human health have been much less analysed. However, invasive species can cause impacts ranging from psychological effects, phobias, discomfort and nuisance to allergies, poisoning, bites, disease and even death. Invasives experts Giuseppe Mazza and Elena Tricarico of the University of Florence, Italy say that in addition to these direct effects, some work in more indirect ways. Humans are menaced by alien invasive species affecting the services provided by ecosystems. “These services are vital to our well-being: changes may decrease the availability of drinking water and of products from fisheries, agriculture and forestry, alter pollination and impoverish culture and recreation,” say Mazza and Tricarico.

The gumwoods of St Helena are flourishing again after facing extinction

At first sight the humble scale insect, Orthezia insignis doesn’t seem like it could pack much of a punch in a ‘fight’ against a range of native flora – but to make such an assumption would be very dangerous indeed.
In fact Orthezia insignis is a genuine invasive menace which in Hawaii, East Africa and South and Central America has, at times, wreaked havoc on numerous ornamental plants including citrus, coffee, olive, Jacaranda and Lantana.

In 1996 in response to the first international meeting on invasive alien species, the Global Invasive Species Programme (GISP) a collaboration between the Centre for Agriculture and Biosciences International (CABI), the International Union for Conservation (IUCN), and the Scientific Committee for Problems of the Environment (SCOPE), was launched. In 2001, GISP published a Global Strategy on Invasive Alien Species, shedding light on the magnitude of these invasive plant and animal species—which destroy agriculture and habitat—and outlined a global-scale response. In addition, the Conference of Parties (COP) to the Convention on Biological Diversity recognized the urgent need to address the impact of invasive species, and in 2002, COP6 included the adoption of Guiding Principles for the Prevention, Introduction and Mitigation of Impacts of Alien Species that Threaten Ecosystems, Habitats or Species.
Research has already shown that invasive species tend to be more tolerant to environmental stress than related non-invasive species. However, a recent study published in Biological Invasions, set out to discover whether this stress tolerance was an inherent trait or whether it was something acquired en route from their natural habitat to the new one.

It was back in the early 1990s, on my first field trip to Assam in North-east India, with invasion ecologist Dr. Sean T. Murphy, when I first encountered mikania growing as an invasive weed. Until then, I had only seen this vine in its Central and South American native range, where locating a population of the plant could sometimes take all day.

Since 2017, CABI has been heavily involved in the international effort to develop and implement a continental framework for tackling fall armyworm in Africa. Initial meetings resulted in the development of a draft framework, which identified roles for different organisations involved in fall armyworm management globally and on the African continent, including CABI. This has culminated into what has officially become known as the Framework for Partnership for Sustainable Management of the Fall Armyworm in Africa.
