| Abstract | ||||
| Some biological aspects of the Acaridae mite, Caloglyphus manuri Eraky & Osman fed on baker's yeast, dry cheese and egg masses of the root knot nematode, Meloidogyne sp. were studied under laboratory conditions at 25±1 oC. Mean life cycle durated 5.90, 7.80 and 10.40 days for C. manuri female and 4.50, 6.40 and 8.10 for male when fed on baker's yeast, dry cheese and Meloidogyne sp. egg masses, respectively. Female life span averaged 21.60, 19.40 and 28.20 days, while it averaged 17.30, 15.80 and 35.8 days for male when fed on the previously mentioned food, respectively. Mean generation time (T) averaged 9.32, 11.82 and 15.85 days, net reproductive rate (Ro) values were 346.40, 298.53 and 83.05 times, net rate of natural increase (rm) was 0.627, 0.482 and 0.278 individual/ /day and the finite rate of increase (erm) was 1.87, 1.61 and 1.32 time/ /day on the same foods, respectively. Doubling time (DT) and gross reproductive rate (GRR) were 1.10, 1.43 & 2.49 ; and 447.28, 368.17 & 127.45 when fed on baker's yeast, dry cheese and egg mass of the root knot nematode (Meloidogyne sp.). Baker's yeast was the most suitable food for rearing C. manuri. | ||||
