我国是世界上发现和应用害虫天敌最早的国家。但我国有组织地开展生物防治科学研究和应用却是在新中国成立以后,如50年代南方柑桔产区从国外引进澳洲瓢虫和国内移植大红瓢虫防治吹绵蚧,引进日光蜂防治苹果绵蚜等,均取得良好的控制效果。随后由于化学农药的广泛推广应用,生物防治的作用曾一度被忽视。自60年代以来,由于化学农药产生的一系列严重副作用,生物防治引起国家和社会各界的重视。据1987年统计,
China is the earliest country in the world to find and apply natural enemies of pests. However, the scientific research and application of biological control in our country has been carried out after the founding of New China. For example, in the 1950s, citrus producing areas in the south introduced the ladybugs from Australia and the domestic ladybugs for transplanting. Cotton aphid, etc., have achieved good control effect. Subsequent to the widespread application of chemical pesticides, the role of biological control was once neglected. Since the 1960s, due to a series of serious side effects caused by chemical pesticides, biological control has attracted the attention of the country and the community. According to 1987 statistics,
