Abstract

The effect of temperature on the biology and life table of Caloglyphus manuri Eraky & Osman fed on egg masses of the root knot nematode, Meloidogyne sp. was determined at 20, 25 and 30 ºC. Its life cycle durated 13.50, 7.92 and 7.42 days for female and 12.65, 7.82 and 7.11 for male when fed at 20, 25 and 30ºC, respectively. Female life span averaged 40.70, 28.47 and 24.37 days; while that of male was 29.50, 26.22 and 16.41 days reared. The mean generation time (T) averaged 21.85,1 2.27 and 11.23 days; while the net reproductive rate (R0) value was 106.51, 94.53 and 58.16 at the aforementioned temperature, respectively. The net rate of natural increase (rm) was 0.213, 0.370 and 0.361 individual / ♀ / day, whereas the finite rate of increase (erm) averaged 1.23, 1.44 and 1.43 time / ♀ / day at 20, 25 and 35 ºC, respectively.
