摘　　要：We evaluated the effects of lithium on the survival, growth, and reproduction ofD. tibetana in the laboratory. The safe concentration value was 69.3 mg/L. The time to first brood was significant lower for individuals reared in 5 and 10 mg/L （24.4 and 24.0 d, respectively） compared with individuals reared in 20, 40, or 60 mg/L. Females reared in 5 mg/L lithium produced a mean of 16.5 neonates/brood and had the highest number of broods （3.0±1.95）. The rate of egg production （a）, the intrinsic rate of increase （rm）, net reproduction rate （R0）, and finite rate of increase （2） were highest for D. tibetana reared at 5 and 10 mg/L lithium, and the duration of development was shorter than for the remaining groups. The results indicated that rearing in 5 10 mg/L lithium can accelerate the growth and reproduction ofD. tibetana.We evaluated the effects of lithium on the survival,growth,and reproduction of D.tibetana in the laboratory.The safe concentration value was 69.3 mg/L.The time to first brood was significant lower for individuals reared in 5 and 10 mg/L(24.4 and 24.0 d,respectively) compared with individuals reared in20,40,or 60 mg/L.Females reared in 5 mg/L lithium produced a mean of 16.5 neonates/brood and had the highest number of broods(3.0±1.95).The rate of egg production(a),the intrinsic rate of increase(r_m),net reproduction rate(R_0),and finite rate of increase(λ) were highest for D.tibetana reared at 5 and 10 mg/L lithium,and the duration of development was shorter than for the remaining groups.The results indicated that rearing in 5-10 mg/L lithium can accelerate the growth and reproduction of D.tibetana.
