To investigate the accumulation patterns of Cd and/or Pb in various body parts, organs and tissues of the Asian gypsy moth (Lymantria dispar) larvae under Cd and/or Pb stress, Cd and Pb treated artificial diets were used to feed the larvae in the current study. These larval body parts/organs/tissues included the heads, integuments (body walls), alimentary canals, fat bodies and hemolymphs. Our results showed that under Cd and/or Pb stress, their accumulations in larval body parts/organs/tissues were significantly higher than those in the control, with the amounts of tested metals in the fat bodies and hemolymphs and alimentary canals being significantly higher than those in the heads and integuments. Under the single Cd (0, 7.5, 10.5 mg/kg) or Pb stress (0, 55, 90, 125 mg/kg), the accumulations of these heavy metals were positively correlated with their concentrations in diets. Under the combined stress (Cd × Pb), the Cd accumulation at the lower Pb concentrations was higher than that at higher Pb concentrations for the body parts/organs/tissues, similar effects of Cd concentrations on Pb accumulations were also recorded. These results clearly showed that Cd and/or Pb were accumulated in various body parts/organs/tissues at different levels under the heavy metal stress. And accumulations of Pb/Cd were positively correlated with their concentrations in the diets under the single stress. Under the combined stresses, Cd and Pb had synergistic effects at low concentrations whereas antagonistic effects at high concentrations. The accumulations of Cd and/or Pb in the gypsy moth larvae affects normal physiological and biochemical functions, and thus affects their growth and development.

研究Cd和/或Pb在亚洲吉普赛蛾（Lymantria dispar）的各个身体部位，器官和组织中的积累模式）在Cd和/或Pb胁迫下的幼虫，在当前研究中，使用Cd和Pb处理的人工饲料喂养幼虫。这些幼虫的身体部位/器官/组织包括头部，外皮（体壁），消化道，脂肪和淋巴。我们的结果表明，在Cd和/或Pb胁迫下，它们在幼虫身体部位/器官/组织中的积累显着高于对照，在脂肪体，淋巴和消化道中被测金属的含量显着高于对照组。那些在脑袋和皮中。在单一镉（0、7.5、10.5 mg / kg）或铅胁迫（0、55、90、125 mg / kg）下，这些重金属的积累与其日粮中的浓度呈正相关。在复合应力（Cd×Pb）下，对于身体部位/器官/组织，较低的Pb浓度下的Cd积累高于较高的Pb浓度，也记录了Cd浓度对Pb积累的类似影响。这些结果清楚地表明，在重金属胁迫下，镉和/或铅在不同水平的人体各部位/器官/组织中积累。在单一胁迫下，日粮中铅/镉的积累与其浓度呈正相关。在联合胁迫下，Cd和Pb在低浓度下具有协同作用，而在高浓度下具有拮抗作用。吉卜赛蛾幼虫中Cd和/或Pb的积累会影响正常的生理和生化功能，从而影响其生长发育。还记录了镉浓度对铅积累的类似影响。这些结果清楚地表明，在重金属胁迫下，镉和/或铅在不同水平的人体各部位/器官/组织中积累。在单一胁迫下，日粮中铅/镉的积累与其浓度呈正相关。在联合胁迫下，Cd和Pb在低浓度下具有协同作用，而在高浓度下具有拮抗作用。吉卜赛蛾幼虫中Cd和/或Pb的积累会影响正常的生理和生化功能，从而影响其生长发育。还记录了镉浓度对铅积累的类似影响。这些结果清楚地表明，在重金属胁迫下，镉和/或铅在不同水平的人体各部位/器官/组织中积累。在单一胁迫下，日粮中铅/镉的积累与其浓度呈正相关。在联合胁迫下，Cd和Pb在低浓度下具有协同作用，而在高浓度下具有拮抗作用。吉卜赛蛾幼虫中Cd和/或Pb的积累会影响正常的生理和生化功能，从而影响其生长发育。在单一胁迫下，日粮中铅/镉的积累与其浓度呈正相关。在联合胁迫下，Cd和Pb在低浓度下具有协同作用，而在高浓度下具有拮抗作用。吉卜赛蛾幼虫中Cd和/或Pb的积累会影响正常的生理和生化功能，从而影响其生长发育。在单一胁迫下，日粮中铅/镉的积累与其浓度呈正相关。在联合胁迫下，Cd和Pb在低浓度下具有协同作用，而在高浓度下具有拮抗作用。吉卜赛蛾幼虫中Cd和/或Pb的积累会影响正常的生理和生化功能，从而影响其生长发育。
