摘要
二甲基甲酰胺对家蚕的毒性较低,只有在很高的浓度食下时才表现出急性中毒死亡,并且随着龄期的增加,家蚕的耐毒性增加,3龄蚕比2龄蚕有更强的耐毒性。低浓度的二甲基甲酰胺(DMF)对家蚕生命率和经济性状都没有显著影响。DMF对家蚕的毒性有积累作用,3龄期连续添毒稀释10倍的DMF原液24h没有观察到急性中毒死亡,但连续添毒90h后,可最终导致家蚕中毒死亡。
Experiment on toxicity of Dimethylformamide to silkworm larvae showed that oral administration of Dimethylformamide in very high concentration（ higher than 10%v/v） could cause lethal effect. However, there was no chronic toxicity to silkworm larvae when its concentration is lower than 20%. With the silkworm larvae grow up, it showed higher tolerant of Dimethylformamide. Moreover, accumulative toxicity effect of DMF on silkworm larvae was observed by continuous feeding with DMF treated mulberry leaves.
