| 摘 要： | 采用电子束辐照处理米象Sitophilus oryzae(Ljnnaeus)成虫,研究在辐照剂量分别为120 Gy、180 Gy、300 Gy、420 Gy、500 Gy、1200 Gy和1800 Gy的处理后害虫体内脂肪酸及相对含量变化.通过GC-MS分析结果表明,米象成虫体内的脂肪酸种类有肉豆蔻酸、棕榈酸、油酸、硬脂酸和十九酸,米象成虫受电子束辐照后,各处理剂量下虫体内的脂肪酸种类都未出现变化,油酸和硬脂酸变化也不显著.但420Gy和500Gy以上的辐照剂量下肉豆蔻酸和棕榈酸含量变化显著,辐照1200Gy以上十九酸含量变化显著.从各脂肪酸的含量变化看,米象虫体内不同种类的脂肪酸受电子束辐照的影响程度存在差异. |

| Abstract: | Fatty acid analysis on adults of Sitophilus oryzae(Linnaeus) was carried out with GC-MS method after electron beam irradiation at the dosage of 120 Gy,180 Gy,300 Gy,420 Gy,500 Gy,1200 Gy and 1800 Gy respectively.The results indicated that the fatty acid from S.oryzae included nutmeg acid,palmitic acid,oleic acid,stearic acid and C19.Under the condition of high dosage of irradiation electron beam,there was a significant influence on the content of fatty acid of S.oryzae adults.In view of changes of fatty aci... |
