Beneficial insects and other arthropods are of great ecological importance because they provide a form of natural pest control, a dynamic process that is responsible for the regulation of pest arthropod populations in nature. Microsporidia (spore-forming protozoan pathogens) infect a wide range of beneficial arthropods, including predaceous lady beetles that are often used for aphid control in agroecosystems. Microsporidia are known to cause chronic, debilitating disease that reduces host fitness; therefore, these pathogens may adversely affect the viability of beneficial arthropods in agroecosystems and in nature.

益虫和其他节肢动物具有重要的生态意义，因为它们提供了一种自然害虫控制形式，这是一种负责调节自然界中害虫节肢动物种群的动态过程。微孢子虫（孢子形成原生动物病原体）感染广泛的有益节肢动物，包括捕食性瓢虫，通常用于农业生态系统中的蚜虫控制。微孢子虫是已知的导致慢性，衰弱的疾病，降低主机健身，因此，这些病原体可能会对农业生态系统和自然界中的有益节肢动物的生存能力产生不利影响。
