Planococcus citri (Hemiptera: Pseuodococcidae), known as citrus mealybug, is a most crucial polyphgous pest on many plants around the world including the grapevine. In this study, information on development, fecundity, survival and population projection of citrus mealybug on grapevine has been collected in the climate chamber 25±1 ºC, 65-70 % RH, and 16:8 (L:D) h photoperiod. The preadult duration of females Pl. citri was 28.31 days, while the preadult duration for male individuals was 26.25 days. Total adult longevity and total longevity times for all cohort were found as 14.81 and 33.97 days, respectively. When reared on 41-B grapevine variety, the net reproductive rate (R0), mean generation time (T), the finite rate of increase (λ), and the intrinsic rate of increase (r) were 32.07 eggs/individual, 41.43 days, 1.087 day-1, and 0.084 day-1, respectively. The population projection showed Pl. citri could increase to population of 357 individuals in 60 days with an initial population of 10 eggs. This study has provided the basic information about the general characteristics of the population of Pl. citri fed on the 41-B grapevine variety and can be useful for IPM studies.
