Abstract:
The experiments were carried out to examine the toxicity of fenpropathrin to zoeal larvae of Macrobrachium rosenbergii (De Man). Values of 24 h EC50 of fenpropathrin for Z1、Z2、Z4、Z6、Z8 were 0.050,0.040, 0.035, 0.030, 0.028μg/L at 30℃ and 0.080, 0.069, 0.060, 0.050, 0.035μg/L at 26℃,respectively. Tolerance of larvae to the toxicant decreased gradually with their developmental stages. On other hand,for the same larval stage the toxicity of fenpropathrin was increasing with the rising of water temperature. higher temperature than at lower one.
