Abstract

Dry yeast granules, cheese and crushed wheat were tested as a nourishment of Rhizoglyphus echinopus (Fumouze & Robin, 1868) under laboratory conditions of 25±1ºC and 70% R.H. Statistical analysis of the obtained results showed that developmental stages, fecundity and life table parameters of the acarid mite , R. echinopus were significantly different among the three types of food, whereas, the total immature stages were (13.08 & 11.9), (13.5 & 12.4) and (16.0 & 15.8  days) for female and male when fed on dry yeast, cheese and crushed wheat, respectively. Female oviposition period lasted (15.7, 20.3 and 23.00 days) and deposited average numbers of eggs & a daily rate (245.4 & 15.86), (190.8 & 9.4) and (101.5 & 4.4) eggs, respectively. Obtained data from the biochemical analysis of food composition showed that the dry yeast granules which have the highest protein content (30.63 %) seem to be an attractive and effective diet for rearing the acarid mite, R. echinopus in the laboratory.
