自从豪沃德和费士克(Howard ＆ Fiske,1911)首次释放微小赤眼蜂防治棕尾蛾以启,不断有人试图广泛应用于其它害虫。但由于大量繁殖的寄主卵不易获得,而一直停留在试验阶段。1927年美国弗兰德斯(Flanders)研究成以麦蛾卵大量繁殖赤眼蜂后,在三十年代出现了较大规模的田间试验与应用。至四十年代, Since Howard & Fiske (1911) first released Tricholoma giganteus for the first time to prevent brown-bellied moth, attempts have been made to find widespread use in other pests. However, due to the large number of breeding host eggs is not easy to obtain, but has stayed in the experimental stage. In 1927, when Flanders of the United States studied to breed Trichogramma with oat moth eggs, a large-scale field trial and application occurred in the thirties. Until the forties,
