Artificially infected adult flies were used in this study. In both Musca species, P. bovicola developed in the fat-body cells, mainly of the abdomen. Escape from the midgut and penetration of the fat-body cell was possibly achieved by use of the cephalic hook of the microfilaria. At 27 degrees C, development to the 3rd larval stage took 9 days, but maximum length was only reached after 11 days. Sharp increases in larval length took place on Days 6-7 and on Day 9. These sudden increase possibly indicate moults to the 2nd and 3rd larval stages respectively. During larval development the fat-body cell increased markedly in size to from a thin-walled capsule around the larva. On reaching the 3rd stage, larvae escaped from the capsules and migrated to the head cavity and proboscis.
本研究使用了人工感染的成年苍蝇。在这两种家蝇物种中，牛微丝蚴在脂肪体细胞中发育，主要在腹部。微丝蚴可能利用头部的钩子从中肠逃脱并穿透脂肪体细胞。在27摄氏度下，发育到第三幼虫阶段需要9天，但直到11天后才达到最大长度。幼虫长度在第6 - 7天和第9天急剧增加。这些突然增加可能分别表明蜕皮到第二和第三幼虫阶段。在幼虫发育过程中，脂肪体细胞大小显著增加，形成围绕幼虫的薄壁囊。到达第三阶段时，幼虫从囊中逃脱，迁移到头部腔室和喙部。
