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 follows carefully controlled laboratory testing to ensure the safe, controlled release of the mite in the UK.
A new Fall Armyworm Portal, which includes the very latest reports and research regarding the devastating crop pest, now features as part of a major upgrade of CABI’s Invasive Species Compendium (ISC) launched today.
Some of the world’s leading scientists in the field of alien invasive plants are to debate how best to tackle the scourge of a range of alien invasive plants – some of whose pollen can cause severe irritation in humans and threaten native ecosystems.
CABI scientists have today warned of the impending rapid spread of the crop-devastating pest, fall armyworm, across Asia following its arrival in India, with major crop losses expected unless urgent action is taken. The warning comes following a pest alert published this week by the Indian Council of Agricultural Research (ICAR) on the website of one of its bureaux, NBAIR, confirming the discovery of fall armyworm in the southern state of Karnataka. CABI scientists warned Asia was at risk from fall armyworm following the pest’s rapid spread across Africa in 2017.
Invasive species experts from CABI have been working in partnership with a range of international organisations, including more than 200 members of a local community and a musical band, to help get rid of the common pest pear Opuntia stricta from the Socotra Archipelago, Yemen.
In the late 1970s and early 1980s the group of closely-related woody plant species and hybrids known as Prosopis were seen as a ‘saviour’ for millions of pastoralists and agro-pastoralists in East Africa whose very livelihoods were threatened by the degradation of dryland ecosystems spurred on by overgrazing, and by deforestation and a shortage of firewood.
A new weapon in the fight against the fall armyworm caterpillar in Kenya is being launched giving thousands of smallholder farmers free expert help and advice on how to tackle the devastating pest through mobile SMS text messaging.
