China’s corn crop at risk from caterpillar
The invasive fall armyworm (Spodoptera frugiperda) is gaining a foothold in China, threatening maize (corn) crops in the world’s second-largest producer. Armyworm outbreaks in Africa and southern Asia have resulted in yield losses as high as 50%. Researchers in China are studying chemicals that could be used to attract the caterpillars into traps, and native insects that could be deployed as a means of biological control. The caterpillar puts further pressure on the food system in China, where African swine fever has pushed farmers to kill more than one million pigs.
WHO resists declaring Ebola emergency

WHO director Tedros Adhanom Ghebreyesus said that “although the spread of Ebola to Uganda is tragic, it is not a surprise” and “the fundamental dynamic” of the outbreak had not changed.
