| 摘 要： | 研究了七叶一枝花提取物Paris polyphylla Smith与增效剂复配对柑桔全爪螨Panoychus citri(McGregor)的毒杀活性.结果表明,七叶一枝花提取物单用对柑桔全爪螨的致死中浓度(LC50)为1 588.537μg/ml,邻苯二酚和氮酮对七叶一枝花提取物均有显著增效作用,致死浓度分别达284.506和768.588μg/ml,分别增效5.6和2.1倍.田间试验结果表明,七叶一枝花提取物与邻苯二酚混用,药后1、3、10、15和20天,校正防效分别达59.74%、71.12%、91.19%、95.50%和95.43%.

| Abstract: | Toxicity of Paris polyphylla Smith and P.polyphylla-synergistic substances mixtures on Panoychus citri(McGregor) were studied by examining the toxicity of P.polyphylla,P.polyphylla mixed with pyrocatechol,calcium sulfate and HP-Ⅰrespectively on P.citri in laboratory.Results showed that the LC50 of P.polyphylla alone was 1588.537 μg/ml.Both Pyrocatechol and HP-Ⅰhad noticeable synergisms and the LC50 was 284.506 μg/ml and 768.588 μg/ml,and the multiple of synergism was 5.6 and 2.1 respectively.The emended effects of the combinations of P.polyphylla and pyrocatechol on P.citri were 59.74 %,71.12%,91.19 %,95.50 % and 95.43 % respectively after 1,3,10,15 and 20 d in field tests. |
