The biology and life table of three acarid mite, Caloglyphus manure Eraky&Osman, Sancassania (Caloglyphus) berlesei (Michael) and Tyroghagus putrescentiae (Schank)  fed on the eggmasses of root-knot nematode Meloidogyn. incognita (Kofoid and White),at 25 ͦC ±1 and R.H 70±10%. Life cycle durated 13.52, 7.92 and 12.6 days for female and 13.17, 7.31 and 11.29 for male of C. manure, S. berlesei and T. putrescentiae, respectively .Female life span averaged 32.72,28.47 and 36.75 days while these of male averaged 19.23, 25.7 and 31.29 days.   The mean generation time (T) averaged 19.45, 12.27 and 17.75days,while net reproductive rate (R₀) values were 83.81, 94.53 and 117.04 time of the aforementioned three mites, respectively.The net rate of natural increase (r_m) was0.227, 0.370 and 0.268 individual /♀/day, while the finite rate of increase (e^rm) averaged 1.255, 1.44 and 1.307 time /♀/day of C. manure, S. berlesei and T. putrescentiae,  respectively. The results indicate the possibility of using Caloglyphus manure, Sancassania berlesei and Tyroghagus putrescentiae in controlling Meloidogyn. incognita .
