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)。 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 Plutellct xylostellh (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 Plutellct xylostella due to Imidacloprid (Y2) and the dilution multiple of 20% Imidacloprid (X) is as Y2 = -0.0804 + 0.0196 ln(X).
