Global agriculture faces a myriad of threats, of which one of the greatest is invasive species. With no native organisms to control them, invasive species such as plant pests and diseases spread out of control, damaging crops and risking the food security of developing countries.

Not Just Maize: Africa’s Fall Armyworm Crisis Threatens Sorghum, Other Crops, Too

By Sara Hendery. Reblogged from Entomology Today.

The fall armyworm (Spodoptera frugiperda) is causing significant damage to maize since its arrival in Africa in 2016, but it is in fact a polyphagous pest. Sorghum, a key cereal crop in Africa (shown here), is also vulnerable, and researchers are working on biocontrol and other integrated pest management methods in hopes of containing the fall armyworm’s impact around the world.

Scientists from the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) in Niger say that 99 percent of the media and research coverage on the fall armyworm focuses on the invasive pest’s deadly threat to maize.

Fall armyworm in Africa: communicating out of a crisis

Interview 1

Take a quick look at the map of the fall armyworm invasion. It gives you a good feel for the number of smallholder farmers in sub-Saharan Africa directly affected by a small caterpillar eating their staple crop – maize – at a rapid rate. As a communication professional working in agriculture, it has been the first time I have found it so easy to explain my work – “ah yes, you are working on this ‘worm’… it is causing so many problems for farmers here” is the response I now get.

Progress made on fall armyworm, but greater effort needed

A major new report published by CABI has today revealed that losses due to fall armyworm are lower than projected in 2017 and the pest is still primarily focussed on maize rather than any other potential host crops. Better monitoring, swift responses by governments and farmers and an increase of natural enemies attacking the pest all help in mitigating the devastating crop losses it can cause.

Indian farmers using smartphones to fight fast-moving crop killer

By Eric Marx. Reblogged from Ethical Corporation.

Plantix is a diagnostic app that uses image recognition software and AI. It is being used to halt the advance of the fall armyworm pest.

Capture

An app that uses artificial intelligence to identify plant disease is being deployed in India as an early-warning system to stop the advance of a crop-destroying caterpillar that is having a devastating impact on maize crops in Africa.

When astronomers meet ecologists: how remote sensing can tackle Parthenium in Pakistan

“Usually I’m looking up at the stars but with this project, I’m back down to earth” quips Dr Rene Breton, Director of Research at the School of Physics and Astronomy at the University of Manchester. By combining the skills of a geographer, ecologist, social scientist, entomologist, astrophysicist, biologist, and electrical engineer, the joint CABI and University of Manchester team aim to capitalise on the unique skills from each subject to tackle the highly invasive weed Parthenium in Pakistan using remote sensing.
