This study of life table parameters, thermal-requirements and development rate of Phenacoccus madeirensis Green, (Hemiptera: Pseudococcidae) reared at 20, 25 and 30°C in department of scale insects and mealybugs laboratory, Plant Protection Research Institute. The main longevity eggs, nymphs,adult female and male development From 20°C to 30°C, greater temperature significantly shortened the period on development regarding every developmental stage. The low aggregate length about nymphal development of females was once 20.65, 28.95 and 47.85 days of 20, 25 and 30°C, respectively. Immature stage about females required a short length (between two or three days) for development than Immature stage males within 20°C in conformity with 30°C. Thehighest percentage on hatching at 25 °C. The percentage of eggs so much survived in imitation of adult male (23%) used to be perfect at 25°C. The survival rates from egg in conformity with adult female was best possible (34.44 %) at 30°C.The effects about P. madeirensis females life table parameters then reared of Potato sprouts at the three examined temperatures 20, 25 or 30C, the mean generation time (T) was once 51.46, 28.64 then 20.71, respectively. The population on P. madeirensis could keep doubled each 8.96, 4.37 or 3.03 days, respectively. The net reproductive rate (Ro), representing the total female births was once 115.09, 93.91 or 53.61. The value on the intrinsic rate of increase (rm) was once 0.08, 0.16 then 0.23 respectively. The finite rate of increase (λ) about P. madeirensis was once 1.08, 1.17 and 1.26 time out of 20°C to 30°C, respectively. Degree day requirements to P. madeirensis required 357.14 DD in accordance with completed theirs improvement beside egg stage in accordance with adult female, while out of egg according to male was 400 DD.
