Invasive weed could cut crop yields by 30 per cent
By Nicholas Okeya. Originally published on SciDev.Net. A dangerous invasive alien weed known as field dodder could be a serious menace to agriculture and biodiversity across Sub-Saharan Africa, and reduce crop yields, scientists say.
CABI-led study recommends improvements to how impacts of Non-Native Species are assessed
CABI has led an international team of Non-Native Species (NNS) specialists who have compiled a list of recommendations to improve the way in which the impact of a range of invasive pests – such as the tomato leaf miner Tuta absoluta – are assessed, potentially helping towards ensuring greater global food security.
Scientists confirm first report of egg parasitoid in Africa to fight devastating fall armyworm
A group of scientists have confirmed the first report of an egg parasitoid Telenomus remus in Africa which could prove an important biological weapon in the fight against the devastating fall armyworm (Spodoptera frugiperda) that threatens the food security of more than 200 million people.
New pest risk analysis decision support tool in development from CABI
A Pest Risk Analysis (PRA) allows National Plant Protection Organisations (NPPOs) to assess risks posed by pests or pathways of quarantine concern, and identify options to manage those risks. Recognising that there was a need for support in the completion of PRAs, CABI, under its Action on Invasives programme, has designed and is developing an…
Two heads may be better than one: using multiple methods in the fight against Tuta absoluta
Tuta absoluta is a major invasive pest that causes devastating crop damage worldwide. Insecticides are heavily relied upon to help curb their numbers, but because of problems with increased insecticide resistance and the environmental impacts of insecticides, scientists are trying to find new ways of fighting this pest.
Asia on alert as highly destructive fall armyworm spreads
By Trudy Harris. Originally published on SciDev.Net. Farmers and authorities throughout Asia need to be vigilant against fall armyworm invasions, after confirmation that the fast-moving pest has spread from India to China and now to South-East Asia, agricultural experts say.
St Kitts-Nevis launches project to minimize harmful effects of invasive alien species
Originally published on WIC News A project aimed at managing the risks and costs of invasive alien species on important ecosystems, species and genetic diversity was launched in St. Kitts and Nevis on Tuesday, at the Ocean Terrace Inn Conference Room.
Alien species are the main cause of recent global extinctions
Whilst many introduced alien species have little effect on the ecosystems in which they exist, others can have devastating impacts on biodiversity, causing extinctions at local and global scales. However, some scientists argue that the impact of alien species has been exaggerated, and suggest that native species are just as likely to cause extinctions. Researchers…
Fall Armyworm attack: ‘Eastern India more vulnerable to infestation’
Originally published on DownToEarth Warmer temperatures increase the metabolism and reproductive rates of the pest Fall Armyworm was first reported in July 2018 in Karnataka. Ever since, it has spread to its neighbouring states. Reports are now coming from West Bengal and Bihar as well. The initial damages are widespread as the pest is a…
CABI announces major commitments in fight against invasive species
Coinciding with its regional consultation with member states in Africa, CABI hosted a policy summit on invasive species in Gaborone, Botswana on 28 February. About 70 delegates representing policymakers, research, the private sector and civil society from across Africa gathered to learn about and discuss the impact of invasives as well as the technical and…
