我省利用赤眼蜂(Trichogramma Spp.)防治落叶松毛虫[Dendrolimus superans(Bu-ther)]始于1969年,但随着科学实验和生产实践的发展,逐渐发现该蜂对落叶松毛虫卵的寄生率低(0—16.3%),防治效果差。到八十年代初,生产单位已不再使用其防治松毛虫。1982—1984年,为摸清赤眼蜂对松毛虫卵寄生率低的原因,我们利用本地松毛虫赤眼蜂(Trichogramma dendrolimi Mats),在保证使用壮蜂和严格按林间放蜂技术操作的条件 Trichogramma Spp. (Dendrolimus superans (Bu-ther)] started in 1969 in our province, but with the development of scientific experiments and production practices, The parasitic rate is low (0-16.3%), the control effect is poor. By the early 1980s, the production units no longer used their control of pine caterpillars. In 1982-1984, we used the Trichogramma dendrolimi Mats to find out why Trichogramma reduced parasitism to Trichinella spiralis eggs. We used this technique to ensure the use of strong bee-eaters conditions of
