微孢子虫是专性细胞内寄生的单细胞原生动物,主要寄生在昆虫体内,是自然界中制约昆虫种群密度的重要因素之一。由于它对人畜无害,不杀伤天敌,不污染环境,因此在害虫的生物防治中,特别是利用昆虫流行病防治农、林及医学昆虫害虫方面日益发挥重要的作用。关于微孢子虫孢子的分离提纯,多用差速离心法及LUDOX HS-40或Percoll密度梯度离心法进行,但差速离心法不能完全提纯
Microsporidia is an obligate intracellular one-cell protozoan parasitic in the body of insects, which is one of the most important factors that constrain insect population density in nature. Because it is innocuous to humans and animals, does not kill natural enemies and does not pollute the environment, it plays an increasingly important role in the biological control of pests, especially in the prevention and control of pests of agriculture, forestry and medical insects by the insect epidemic. On the separation and purification of microsporidian spores, and more use of differential centrifugation and LUDOX HS-40 or Percoll density gradient centrifugation, but not completely purified by differential centrifugation
