| 为筛选出与乙基多杀菌素复配具有增效作用的杀虫剂组合, 采用叶管药膜法测定了乙基多杀菌素分别与啶虫脒、毒死蜱、阿维菌素、高效氯氰菊酯复配对黄胸蓟马2龄若虫的联合毒力, 并采用共毒系数法评价了复配组合的联合作用。结果表明, 乙基多杀菌素与啶虫脒在配比为3∶7、5∶5、7∶3和8∶2时, 与毒死蜱在所有配比组合中, 与阿维菌素在配比为2∶8、3∶7和6∶4时, 其共毒系数(CTC)均大于120, 表现出显著的增效作用; 而与高效氯氰菊酯在所有配比下均不具有增效作用。乙基多杀菌素与啶虫脒、毒死蜱、阿维菌素采用上述具有增效作用的复配比复配, 在害虫治理和抗性治理中具有一定的应用前景和开发潜力。 |
| 英文摘要: |
| To screen synergistic mixture of spinetoram with other four insecticides against Thrips hawaiiensis, the co-toxicity of spinetoram with acetamiprid, chlorpyrifos, abamectin and beta-cypermethrin against the second instar nymphs of T.hawaiiensis was tested under the mass ratio of 1∶9, 2∶8, 3∶7, 4∶6, 5∶5, 6∶4, 7∶3, 8∶2 and 9∶1, respectively. The toxicity was determined by leaf-tube residual bioassay method in the laboratory, and the synergism was evaluated by co-toxicity coefficient method. The results demonstrated that the mixture of spinetoram and acetamiprid with the mass ratio of 3∶7, 5∶5, 7∶3 and 8∶2, spinetoram and chlorpyrifos with all the tested ratios, and spinetoram and abamectin with the mass ratio of 2∶8, 3∶7 and 6∶4, showed a higher co-toxicity coefficient (CTC) of over 120, indicating significant synergism. Nevertheless, CTC in the mixture of spinetoram and beta-cypermethrin with all the tested ratios was less than 120, showing non-synergism. The results taken together indicated that the mixture of spinetoram and acetamiprid, chlorpyrifos, abamectin could be used in pest management and insecticide resistance management of T.hawaiiensis. |
