| 摘 要： | 通过在人工饲料中添加不同质量分数的Zn2+,研究了植食性昆虫斜纹夜蛾Spodoptera litura Fabricius连续3代幼虫取食含不同质量分数Zn2+饲料后,第1和第3代6龄幼虫不同组织对Zn2+的积累作用。结果表明,经连续3个世代的胁迫,Zn2+在第1、3代斜纹夜蛾6龄幼虫脂肪体、表皮和中肠中的积累量随幼虫饲料中Zn2+ 质量分数及胁迫时间的增加而升高;中肠对Zn2+的积累作用最强,表皮次之,脂肪体最低。

| Abstract: | Zinc accumulation in different tissues of 1stand 3rd phytophagous insect Spodoptera litura Fabricius larvae were investigated by adding various doses of zinc into artificial diets of S. litura larvae. Inductively Coupled Plasma Atomic Emission Spectrometer (ICP AES) was used to measure the concentration of zinc in different tissues of S. litura larvae. Results showed that zinc was accumulated in the midgut,fat body and cuticle of 6th instar larvae in the 1stand 3rd generations of S. litura.Accumulations of Zinc in different tissures increased with the increasing zinc doses in diets and the dose response with zinc doses in diets was singificant. The concentration of zinc in midgut was the highest among the three kinds of tissues. |
