Mononchid nematode, lotonchus monhystera was cultured in 1% soil-beef extract agar. Estimate of biotic potential i.e. intrinsic rate of natural increase was calculated from the data generated on generation time and rate of egg production by individual female. Equation for these variables in the laboratory cultures within the temperature range of 5 to 33°C were derived. Predation efficiency of I. monhystera was studied in agar as well as in soil. Percentage of predator causing 50% predation of Meloidogyne incognita and Pratylenchus zeae within five days in soil was cnlculated by profit-log dose analysis.
