| Abstract: | Compared with artifical diet containing Bacillus thuringiensis, addition of inorganic salts could enhance larvicidal activity. In this experiment, Calcium salts, Magnesium salts, Zine salts, and copper salts was added respectively. They had different synergistic effect. Calcium carbonate and Calcium chloride increased Bt potency by 0. 24 times and 0. 28 times respectively. Magnesium sulfate and Magnesium chloride increased potency by 0.66 times and 3. 19 times respectively. Zine chloride and Zine sulfate increased potency by 0. 43 times and 2. 03 times, Copper chloride, Copper sulfate increased potency by 0. 28 times and 0. 16 times respectively. Among these inorganic aslts, Magnesium chloride was the hot effective in erhancing the potency of Bacillus thuringiensis. zine sulfate was the second effective. |
