The nutrient composition of postparasitic females (newly emerged juveniles, newly molted adults, and spent adults) and eggs of Romanomermis culicivorax was studied. Throughout post-parasitic development, proteins increased and lipids decreased progressively as a proportion of the dry weight; the proportion of glycogen within the nematodes remained stable. The greatest decrease in the lipid moiety occurred during egg production. Eggs contained relatively low levels of lipids (12% dry weight), and ca. 20% of the dry weight of the eggs was unaccounted for by lipid, protein, and glycogen determinations. Chitin, mucoproteins, and peptides were present in the eggs. The fatty acid composition of nematodes remained constant during postparasitic development; eggs contained a similar profile of fatty acids as postparasites, with marginally higher content of unsaturated fatty acids. Radiotracer studies showed that the eggs could oxidize glucose and palmitic acid.
对食蚊罗索线虫寄生后雌虫（新羽化的幼虫、新蜕皮的成虫和产卵后的成虫）及卵的营养成分进行了研究。在寄生后发育过程中，蛋白质占干重的比例逐渐增加，而脂质占干重的比例逐渐降低；线虫体内糖原的比例保持稳定。脂质部分的最大降幅出现在产卵期。卵中脂质含量相对较低（占干重的12%），通过脂质、蛋白质和糖原测定发现，约20%的卵干重无法得到解释。卵中存在几丁质、粘蛋白和肽。线虫的脂肪酸组成在寄生后发育过程中保持不变；卵中脂肪酸谱与寄生后雌虫相似，不饱和脂肪酸含量略高。放射性示踪研究表明，卵能够氧化葡萄糖和棕榈酸。
