【摘要】 取食农药吡虫啉后,小菜蛾对阿维菌素的敏感性会随着取食量差异而受到影响。1.8%阿维菌素对小菜蛾的LC50浓度稀释倍数(Y1)与20%吡虫啉浓度稀释倍数(X)之间存在显著的线性相关关系,函数式为:Y1=14205-1248.8 ln(X);而20%吡虫啉处理过的小菜蛾羧酸酯酶比活力(Y2)与20%吡虫啉浓度稀释倍数(X)之间的线性相关关系函数式为:Y2=-0.0804+0.0196 ln(X)。更多还原

【Abstract】 The toxicity study was conducted to test the Imidacloprid influence on the Abamectin susceptibility of Plutella xylostella.The linear regression equation for the relationship between the LC₅0（dilution multiple） of Abamectin to Plutella xylostella（Y1） and the dilution multiple of 20% Imidacloprid（X） is estimated as Y1=14205-1248.8 ln（X）;and that for the CarE activity index of Plutella xylostella due to Imidacloprid（Y2） and the dilution multiple of 20% Imidacloprid（X） is as Y2 = -0.0804 + 0.0196 ln（X）.更多还原
