A historical review of the prevention and treatment of locust calamities in China since 1949

Each occurrence destroys a huge area, severely threatening the security and the growth of value of agricultural production, and even the social stability. Since the founding of New China, however, efficient measures have been taken to deal with the locusts. A rescue system has been set up with chemical prevention and geographical projects. In addition, a series of preventive projects since 1950s till 1980s have substantially improved from prevention stage to curing, and eradication stage. Hence, with the increasingly preventive competence of locust calamities, China has basically achieved the bio-ecological environment.
