Nosema locustae, a microsporidian parasite of locusts and grasshoppers, was transovarially transmitted to the progeny of infected Locusta migratoria reared for up to F14 generations. The mortality of infected progeny in each generation was higher than that of uninfected controls and ranged from 67.6% to 95.5%. Infected female survivors transmitted the microsporidium to the progeny via eggs. The developing eggs harboured vegetative stages of N. locustae, and development of the microsporidium occurred during embryonation. Spores accumulated in the yolk and, after blastokinesis, both the yolk and the spores were enclosed in the midgut of the embryo. Germinated spores infected the functional midgut epithelium and invaded internal tissues. The mortality of newly hatched instars was high when embryonic tissue had been infected during development.
蝗虫微孢子虫是蝗虫和蚱蜢的一种微孢子虫寄生虫，它通过卵巢传递给连续饲养至F14代的受感染飞蝗后代。每一代受感染后代的死亡率均高于未受感染的对照，范围在67.6%至95.5%之间。受感染的雌性幸存者通过卵将微孢子虫传递给后代。发育中的卵含有蝗虫微孢子虫的营养阶段，微孢子虫的发育发生在胚胎发育期间。孢子在卵黄中积累，在胚动后，卵黄和孢子都被包裹在胚胎的中肠内。当胚胎组织在发育过程中受到感染时，新孵化幼虫的死亡率很高。
