Desert locusts have plagued farmers in Africa and Asia since Pharaonic times and are mentioned in both the Bible and the Quran. Since the UK's establishment of the Anti-Locust Research Centre in 1945, four major international conferences have been held to formally establish a method of monitoring, controlling and preparing for future outbreaks.
