1. Introduction
China is a country with many agricultural pests. According to statistics from the Chinese Ministry of Agriculture (2007), the area of pest infestation during 1990–2000 was about 300 million hectares per year and the annual loss of food crops destroyed by pests was over 15 billion kilograms, even though various measures of control were applied. During this time, pest control was mainly dependent on chemical pesticides, and the yearly total amount applied was as high as 250,000 tons of active ingredient (Qiu, 2005). Owing to ever-increasing problems of environmental pollution and food safety caused by chemical pesticides, the Chinese government recently provided more support to the development of an environmental friendly strategy of biological control. As a result, China has made very significant progress in developing microbial control programs.
2. Current status of microbial control
2.1. Biopesticide production, microbial insecticides and pest control
Currently, China has established an integrated research and development system with multiple disciplines for biological control, including microbial control. Microbial control has played an important role in Chinese pest management. According to estimates by the Ministry of Agriculture in 2004, the output of all biopesticides (including microbial agents, agro-antibiotics, biochemical agents and botanical pesticides) and application area, respectively, accounted for 12% and 9.5% of total output
