摘  要：
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。

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 and9∶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 betacypermethrin with all the tested ratios was less than120,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.
