0. 824和 0. 982;其脂肪酸分别占总脂肪的 59. 66%和 69. 72%，多不饱和脂肪酸和饱和脂肪酸含量的比值为 0. 44和 0. 29;此外，鼻优草螽还含有丰富 Ca、Fe、Zn、Na、Cu、Mn、P等矿质元素和微量元素。在分析了鼻优草螽的资源成分基础上，对其开发利用价值进行了评价。
英文摘要：The nutritional composition of Euconocephalus nasutus Thunberg from grassland and paddy fields wasdetermined． The results show thatE． nasutus from both these two habitats contained abundant nutrients，the relative percentages of each being; protein (18. 39% and 9. 34%)， fat (5. 93% and 13. 22%)， ash (0. 65% and 0. 52% ) and carbohydrate (0. 27% and 0. 28% )． Total amino acid content of samples from grassland and paddy fields were 19. 832 mg / g and 10. 957 mg / g respectively，of which were 45. 185% and 49. 557%essential amino acids． Ratios of essential tounessential amino acids from the two habitats were 0. 824and 0. 982 respectively． Ratios of unsaturated to saturated fatty acids in insects from each habitat were 0. 5966 and 0. 6972，respectively，whereas ratios of polyunsaturated to saturated fatty acids were 0. 44 and 0. 29.E． nasutus contained minerals and trace elements，including Ca、Fe、Zn、Na、Cu、Mn、P． The potential for the utilization ofE． nasutuswas evaluated in light of these data．
