Abstract | ||||
Biological studies were canied out on the grain mite, Dermatophagoides farinae Hughes when feding on three different types of food ( dry yeast, crushed wheat and crushed rice) under laboratory conditions of 25 & 30°C and 60 % RH. Developmental stages and female fecundity of mites were affected by different food types and temperature where female total immature stages lasted (15.2 &14.1),(16.4 &14.5) and (17.6 &15.8) days at 25 and 30°C when mite fed on dry yeast, crushed wheat and crushed rice, respectively. Adult female and male longevity durated (28.6 & 25.8), (32.1&27.7) and (35.4& 29.0) days at 25°C when mite fed on the above mentioned diets ,respectively. Female fecundity was also affected by both food and temperature where the average number of deposited eggs and the daily rate were (65.2,55.9) (53.2&44.4) and (45.5&35.2) when mite fed on dry yeast, crushed wheat and crushed rice at 25 and 30°C, respectively. | ||||
