| Abstract | ||
| Biological studies were carried out on the acarid mite, Rhizoglyphus callae Oudemans, where it fed on three different types of food, dry yeast granules, crushed wheat and crushed maize to study the effect of these sources on developmental stages, fecundity and life table parameters as food materials under laboratory conditions of 25+1 °C and 70 % R.H. Obtained results and statistical analysis cleared that developmental stages, fecundity and life table parameters of the mite were affected by different types of food, whereas, the total immature stages lasted (8.9 &7.33), (10.7&9.5) and (14.6&12.65) days for female and male when fed on the above mentioned diets, respectively. Female oviposition period lasted (12.0, 17.8 and 17.8 days) and deposited an averages numbers of eggs, with a daily rate (163.2 &13.11), (111.8 &8.1) and (87.0 &4.89) eggs of the same trend. Female percentage ranged between 58.11& 66.73 %.Diet of dry yeast provided the shortest generation time (G), and female longevity as well as greatest fecundity (F) which increased (exp rm) to 1.88 per day,, while the diet crushed maize was the least suitable diet with results of 23.6, Ro = 43.6, rm = 0.34 and fraction of eggs reaching maturity M= 0.64. The intrinsic rate of increase (rm) values were highly affected by generation time and mean fecundity. | ||
