Study was carried out in the laboratory of zoology department, Faculty of Science for G iris1 Al-Azhar University. The biology and control of C.lactis L., with three temperature. As temperature increased from 20 C to 30 °C the average of life cycle decreased from 21.3 to 9.3 days for females and from 18.4 to 8.7 days for males when fed on potato tuber at RH 70 ± 5 %. Average of adult longevity decreased from 21.6 to 18.3 days from females and from 15.2 to 12.0 days for males and 41.2 egg to 79.3 eggs, respectively. Thus 25 °C was most suitable degree for C. lactis rearing and reproductîon this ¡s supported by life table parameters at 20, 25 and 30 C, C. Iactis fed on potato tuber immatures gave the least natural intrinsic rate an increase (rm = 0.22 1 female I day ) at 20 °C, the net reproductive rate (Ro) 31.68 times and the finite rate of increase (expm) 1.23 times I female I day. Although the rate of female survival (Lx) was highest at 20 oc than 25 and 30 oc yet specific rate of fecundity. Stored products are better to be stored than 20 °c
