The gypsy moth, , is a notorious forest defoliator, and various pathogens are known to act as natural regulators of its population density. As a widespread herbivore with a broad range of inhabited areas and host plants, it is potentially exposed to parasitic microorganisms from other insect hosts. In the present paper, we determined the susceptibility of gypsy moth larvae to the microsporidium from the European corn borer, . Gypsy moth samples from two localities of Western Siberia were used. developed infections in the salivary gland and adipose tissue of gypsy moth prepupae and pupae, forming spore masses after 30 days of alimentary exposure to the second instar larvae. Among the experimental groups, the infection levels ranged from 0 to 9.5%. Effects of a covert baculovirus infection, phenylthiourea pretreatment and feeding insects on an artificial diet versus natural foliage were not significant in terms of microsporidia prevalence levels. Thus, showed a low level of susceptibility to a non-specific microsporidium. It can be referred to as a resistant model host and not an appropriate substitute host for laboratory propagation of the microsporidium.
舞毒蛾是一种臭名昭著的森林食叶害虫，已知多种病原体可作为其种群密度的自然调节因子。作为一种广泛分布的食草动物，栖息地和寄主植物范围广泛，它有可能接触到来自其他昆虫寄主的寄生微生物。在本文中，我们测定了舞毒蛾幼虫对来自欧洲玉米螟的微孢子虫的易感性。使用了来自西西伯利亚两个地区的舞毒蛾样本。在舞毒蛾预蛹和蛹的唾液腺和脂肪组织中发生感染，在对二龄幼虫进行30天的经口暴露后形成孢子团。在实验组中，感染水平在0%至9.5%之间。就微孢子虫的流行水平而言，隐性杆状病毒感染、苯硫脲预处理以及用人工饲料喂养昆虫与用天然树叶喂养昆虫的影响并不显著。因此，舞毒蛾对非特异性微孢子虫的易感性较低。它可被视为抗性模型寄主，而不是微孢子虫实验室繁殖的合适替代寄主。
