locusts on the wane

It’s not often we can report on some good news associated with climate change. But it seems that warming temperatures could give welcome respite to farmers – in China, at least – by suppressing locust plagues.

Zhibin Zhang of the Chinese Academy of Sciences and colleagues found that the Oriental migratory locust (Locusta migratoria manilensis), which has been named as one of the most damaging agricultural pests in Chinese history, operates on a climate-driven cycle.

Every 160 to 170 years, the swarms get bigger then subside again.
