CABI scientists have made the first discovery of the Asian samurai wasp Trissolcus japonicus – a natural enemy that kills the eggs of the the invasive fruit and nut pest brown marmorated stink bug (Halyomorpha halys) – in Europe.
Judith Stahl and Dr Tim Haye led an international team of researchers, including those from the University of Turin and the USDA Agricultural Research Service, who used DNA analysis to confirm the wasp – which is native to China, Japan and Korea – was found in Switzerland in 2017.
CABI’s experts in the biological control of agricultural pests and diseases have conducted the first major study of potential biological controls that could be used in the fight against the devastating fall armyworm which recently arrived in Africa.
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.
