Fall armyworm has devastated millions of hectares of maize and sorghum in Africa The highly destructive moth (Spodoptera frugiperda), native to North and South America, has been steadily moving east since 2016, causing up to US$3 billion worth of damage to maize and other crops in Africa, according to reports. The pest reached India in July last year before hitting Bangladesh and Sri Lanka. During the last 6—7 months, fall armyworm has spread from India to China, and will continue to  spread in China. It has reached Myanmar and Thailand and it will also spread to Vietnam sooner or later” The biological weapon, known as Telenomus remus, is an egg parasitoid — an insect that completes its larval development within the body of another insect leading to the death of its host. It is already being used to tackle fall armyworm in the Americas.
