玉米螟微孢子虫(Nosema pyrausta)是寄生玉米螟(Ostrinia furnacalis)的原生动物。我们于1982～1983年在网室进行了应用微孢子虫防治玉米螟试验。结果表明,不仅对当代虫口有抑制能力,而且对下一代虫口也有影响。一、材料和方法试验共建处理网室和空白网室各1个。每个网室面积1分地。种植“中单2号”品种玉米。处理网室在玉米心叶期(7月6日)防治第一代玉米螟。共设3个处理:1、 Nosema pyrausta is a protozoan of the parasitic Ostrinia furnacalis. We conducted the application of microsporidia to corn borer in the net room from 1982 to 1983. The results show that not only inhibit the ability of contemporary insect population, but also affect the next generation of insect population. First, the materials and methods to test the construction of processing network room and a blank mesh each one. Each net room area of ​​1 minute. Planting “Zhongdan 2” variety of corn. Processing net room in the corn leaf period (July 6) prevention and control of the first generation of corn borer. A total of three processing: 1,
