A pest known as the flyworm has caused a significant impact on corn crops, with a 4% shortfall in China's crop resulting in a loss of 11 million tons and a price increase that led to the country using its strategic reserves. The pest also affected about 15% of Zambia's corn crop. The non-profit CABI reports that climate change is aiding in the spread of this and other pests, including the western corn root beetle, coffee beetle, desert locust, soybean gall midge, and spotted fruit fly, which pose a threat to global food security and require mandatory control.
