摘要
阿维菌素、三唑磷LC50分别为对泥鳅的24~96h致死中浓度,0.031~0.064mg/L、3.771~5.434mg/L,对泥鳅的急性毒性分别为高毒和中毒。2者按浓度1∶1混配后24h,对泥鳅毒性具有协同增效作用,48、72、96h具有毒性相加作用。
The acute toxicity test of abamectin and triazophos on misgurnus dabrvanus were carried out. The results showed that the LCso of abamectin and triazophos on misgurnus dabrvanus were 0.031-0.064mg/L and 3.71 1-5.434mg/L at 24-96h after treatment. Their toxic grade was high and moderate respectively.
