Last month the International Institute for Sustainable Development (IISD) reported that an international measure that aims to prevent the spread of invasive aquatic species had come into force (see the full article on the IISD website).
CABI has published an ‘evidence note’ report on the invasive Fall Armyworm pest, showing how the caterpillar could cause maize losses costing 12 African countries up to US$6.1 billion per annum, unless control methods are urgently put in place. Continue reading
Removing the flowers of an invasive shrub from mosquito-prone areas might be a simple way to help reduce malaria transmission, according to a new study published in the open access Malaria Journal. Removing the flowers from villages in Mali decreased the local mosquito vector population by nearly 60%. Continue reading
According to new research, scientists found that a number of invasive alien plant species initially introduced as ornamental plants at tourism facilities are now spreading rapidly throughout the Serengeti-Mara ecosystem, posing a major threat to wildlife, including the annual wildebeest and zebra migration as well as a range of other plant and animal species.

The European Earwig, Forficula auricularia (order Dermaptera) was recently introduced to the Falkland Islands and has since become locally common in Port Stanley and a number of settlements in both East and West Falkland. Since its introduction this invasive species has caused considerable problems ranging from yield losses in horticulture to health and safety issues (eg. hiding behind rubber seals in oxygen masks or in asthma inhalers) and threats to the indigenous ecosystems. There are now worrying observations of earwigs away from settlements indicating a considerable threat to the composition of native invertebrate communities. The exact date when earwigs were first introduced is unknown but early records stem from as far back as 1997. Earwigs have become a real nuisance pest since the mid-2000s. Continue reading
New research by CABI reveals that just five invasive alien species are causing US$0.9 – 1.1 billion in economic losses to smallholder farmers across six eastern African countries each year, equating to 1.8% – 2.2% of total agricultural GDP for the region. These losses are expected to grow to $1.0 – 1.2 billion per year over the next 5-10 years, highlighting the urgent need for coordinated responses at regional, national and international levels.

It is the end of December 2016, with clear skies over Niger. But as 2017 draws near prospects are grim for some 500 residents in Bani Kosseye, a village 80km from the capital Niamey. Agricultural production has been poor here, and families’ meagre stocks are expected to run out within a few weeks. People already fear famine. Continue reading
