输引害虫天敌进行生物防治称为“传统生物防治”,可以渊源至1873年,为了防治从北美传入欧洲的葡萄根瘤蚜,将北美的根瘤蚜粉螨输引至法国。输引瓢虫防治介壳虫、粉虱、蚜虫等害虫,非但历史悠久,而且应用广泛。为此,按其效果进行全面的历史回顾。 据统计,全世界共有15种瓢虫输引完全或大体成功地防治19种害虫;有4种瓢虫输引部分成功地防治4种害虫。据Gordon(1985)报导,自1888年后,共有179种瓢虫被输引至北美,其中有25种确定已经定居,约占14％。 从澳洲瓢虫等所建立的功勋中得到启示:
The biological control of insect pest infestation is called “traditional biological control” and can be traced back to 1873. In order to control the grape phylloxera from North America introduced into Europe, the North American phylloxera is transported to France. The ladybug is introduced to control scale insects, whitefly, aphids and other pests, not only has a long history, but also has a wide range of applications. To this end, according to the effect of a comprehensive historical review. According to statistics, a total of 15 kinds of ladybugs worldwide were successfully or totally controlled for the control of 19 pests. Four kinds of ladybugs were successfully used to control 4 pests. According to Gordon (1985), 179 species of ladybugs have been exported to North America since 1888, of which 25 have been identified as settled, accounting for about 14%. Insights from the merits of the Ladybugs in Australia:
