自1882年加拿大最早进行施放试验以来,应用赤眼蜂(Trichogramma spp.)防治害虫有了很大发展。世界上许多国家先后进行试验研究,并在生产上实际应用。九十多年来的发展过程大致可分三个阶段。早期由于没有掌握规律,也没有找到合适的繁蜂寄主卵,只作一些小规模的探索性试验,仅涉及少数几种害虫。本世纪三十年代,由于美国发展用麦娥(Sitotrogacerealella Oliv.)卵繁殖赤眼蜂的技术,很快促进了这一工作的推广。四、五十年代有机化学农药盛行一时,很多国家忽视生物防治,到了五、六十年代,化学防治 Trichogramma spp. Has been used to control pests a great deal since the earliest launch in Canada in 1882. Many countries in the world have carried out experimental research in succession and have practical applications in production. The development process in more than 90 years can be broadly divided into three stages. In the early days, there was no proper regulation of the law and no suitable host of bee-pollinators, but only some small-scale exploratory tests involving only a few pests. The promotion of this work was quickly promoted by the United States in the 1930s as the United States developed the technology to breed Trichogramma with the eggs of Sitotrogacerealella Oliv. In the 1950s and 1960s, there was a sudden prevalence of organic chemical pesticides. Many countries neglected biological control. By the 1950s and 1960s, chemical control
