摘要
定了碱性、酸性和中性化合物及蛋白质助溶剂和芳香族化合物等 5类物质对 Bt杀虫效果影响 ,结果表明有 30种物质能促进 Bt杀小菜蛾的效果 ,其中碱性物质 11种 ,酸性物质 3种 ,中性盐 8种 ,蛋白质助溶剂5种 ,芳香族化合物 3种。在各类不同的化合物中以硼酸和 K2 CO3 对 Bt杀虫效果的促进作用较强。
Chemical additives have been used to enhance the activity of Bt against Plutella xylostella. Chemicals of various groups were assessed with respect to their effect in increasing the activity of fermentative liquid of Bt. Using leaf-dip bioassay, preliminary screened 46 chemical additives. The result indicated that 30 additives, including 11 alkaline compounds, 3 acidic compounds, 8 inorganic salts, 3 aromatic compounds, 5 protein solubilizing agents, were able to increase the efficacy of Bt at 1% concentration. Among the 30 compounds boric acid and potassium carbonate were better to increase the activity of Bt.
