Ruffling parrot’s feathers: the biological control of Myriophyllum aquaticum
Myriophyllum aquaticum, commonly known as parrot’s feather, is an invasive aquatic weed. It can have roots underwater in depths of up to 1.5 metres with shoots that appear 20-50cm above the water surface. This makes it both a submerged and emergent plant. It is native to South America but is a popular garden and aquarium…
Insect heroes fighting invasive species
Today marks the beginning of Insect Week (21-27 June) – a week to learn more about the science and natural history of insects. We are highlighting some of the insect heroes, and villains, CABI scientists work with on a regular basis. Scientists at CABI’s Egham laboratory work with a range of insect species, from plant-parasitic…
Controlling Himalayan balsam, one of the UK’s most invasive weeds
Himalayan Balsam’s beautiful pink flowers appear between June and September. We take a look at Himalayan balsam (Impatiens glandulifera), one of the UK’s most invasive and problematic weed species, and the work CABI is doing to combat its spread. Why is Himalayan balsam such a big problem?
Potential Slug Invasions and their Impact on UK Biosecurity (Part 2)
By Dr Jenna Ross Guest writer, Dr Jenna Ross, from Crop Health and Protection (CHAP), joins us for the second of her two-part special series (read part 1) on the outputs of her prestigious Nuffield Farming Scholarship. Jenna spent 26 weeks travelling the world studying all aspects of slug invasions and slug control, and in…
Tiny mite could prove a ‘mighty’ weapon in the fight against one of the UK’s most invasive weeds
CABI scientists are stepping up the fight against one of the UK’s most invasive non-native aquatic weeds. Approval has been given for the release of a novel biological control agent – the mite, Aculuscrassulae – to assess its ability in the real-world environment to suppress Australian swamp stonecrop (Crassula helmsii), also known as New Zealand pigmyweed. This…
Enlisting microbes to enhance Himalayan balsam biocontrol
Building on CABI research into the biological control of Himalayan balsam (Impatiens glandulifera) using a rust fungus (Puccinia komarovii var. glanduliferae), a Natural Environment Research Council (NERC) funded collaboration between Royal Holloway, CABI and the University of Reading is investigating the role of the microbial community associated with the plant and how these microbes may…
CABI releases rust fungus to control invasive weed, Himalayan balsam
26 August 2014 – From today, not-for-profit research organization, CABI, will be releasing a rust fungus at locations in Berkshire, Cornwall and Middlesex as part of field trials to control the non-native, invasive weed Himalayan balsam (Impatiens glandulifera) using natural means. Himalayan balsam has rapidly become one of the UK’s most widespread invasive weeds, colonizing…
The advance of the Asian hornet creates a buzz in the UK media
Some of the species that are included in our open-access Invasive Species Compendium are well known to the general public, for example Japanese Knotweed. Others are more obscure, and I had never heard of the Asian Hornet, Vespa velutina, until I edited the datasheet about it earlier this year. I was therefore interested to hear…
