近百年来,国外害虫生物防治的重点,是放在输引害虫天敌的试验研究上,并且将此途径称为“传统生物防治”(Classical Biological Control)(DeBach,1974)。 Luck(1981)统计了自1881年至1977年全世界输引各地(包括国内移殖)天敌昆虫的试验共2593例,防治粮食、油料、糖料、饮料、果树、蔬菜、林木、牧草等作物上以及卫生上的有害生物共315种,隶属于10目66科。输入的国家遍及亚、非、拉、欧、澳和南、北美等洲共67个国家(不包括地区)。其中取得成功或大体上成功的试验共391例,
Over the past century, the focus of biological control of pests in foreign countries has been on the experimental research on the introduction of pests and natural enemies, and this approach is called “Classical Biological Control” (DeBach, 1974). A total of 2593 experiments were carried out by Luck (1981) to map natural enemies of insects around the world (including domestic colonies) from 1881 to 1977 to control crops such as grain, oilseeds, sugar, drinks, fruit trees, vegetables, trees and pasture There are 315 species of pests in health and hygiene, belonging to 10 orders and 66 families. The importing countries cover 67 countries (excluding regions) in Asia, Africa, Latin America, Europe, Australia, South and North America. Among them, 391 cases were successful or generally successful,
