What is the fall armyworm and why should we worry?
The fall army worm is (was) native to the Americas shifting between North and South America based on weather. A corn shipment (most likely) across Atlantic transported the worm to the African continent. After reaching Africa in 2016 there has been no stopping the worm. It has taken a liking to the warmer climates. The worm took the land route across Africa, the Middle East, South Asia into South East Asia and China. It is now a global conqueror.
The worm has devastated crops in over 50 countries:
It was first detected in India in early 2018 and has destroyed maize crops in many states. Many of the maize farmers in India are small, rain-dependent croppers who get one shot for agricultural income every year.
