BEIJING, China (Reuters) — Agriculture officials in northern China’s Shandong province warned July 30 that an infestation of the fall armyworm pest will spread further in the key corn-producing area, posing a major threat to crop output in the region.
The insect has already caused damage in some areas in Shandong, China’s third-largest corn producer after Heilongjiang and Jilin in the northeast, and the situation has developed rapidly, the Shandong Agriculture and Rural Affairs Bureau said in a statement.
Fall armyworm feasts in large numbers on the leaves and stems of many plant species, and can infest and damage hundreds of acres of corn overnight.

The destructive pest has spread to 21 provinces and regions in China since it was first detected in the southwestern province of Yunnan in January, infesting 1.9 million acres of land growing corn in the first half of the year, according to a report from a government-backed agriculture institute.
China had about 320 million acres of arable land as of the end of 2017 and grows corn on about 105 million acres.
The rainy season, which in northern China runs from July to September, will facilitate the migration of a large number of adult insects into Shandong, the province’s agriculture bureau said.
