Abstract: The 48-h LC50 value of Galla Chinansis to Moina macrocopa was studied by acute toxicity test. The influence of Galla chinensis(1.25, 2.50, 5.00, 10.00, 20.00, 40.00 mg/L)on the statistical parameters of life table of Moina macrocopa was studied by means of life table test. The results showed that Chinese herbal medicine Galla Chinansis had significant effect on survival rate and reproduction rate of Moina macrocopaP<0.05), and the 48-h LC50 of Galla Chinensis on Moina macrocopa was 79.57 mg/L. The life table parameters showed that the population intrinsic growth rate and net reproductive rate were significantly decreased(P<0.05)at high concentration(40 mg/L), and the values were [(0.015 3±0.007 6)h-1] and [(1±0.67)ind.] respectively.

Key words: Galla Chinansis, Moina macrocopa, 48-h LC50, intrinsic population growth rate, net reproductive rate
