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.

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

Colorado beetle eats a potato leaves young.

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 online PRA tool.

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.

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 from University College London set out to determine if this was the case. Continue reading
