The demography of Paronychiurus kimi, a dominant collembolan in paddy fields of Korea, was quantified for four treatments of the herbicide paraquat (0, 1.6, 16, 160 and 1600 microg/cm(2)) in a controlled environment using plaster-of-Paris as the test substrate. The survival rate of adults and the reproductive fitness of P. kimi were not affected by paraquat except at the highest dosage (1600 mi...
