Özet

The development, reproduction, and life table parameters of the Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae) on four ornamental plant species, namely Pelargonium zonale (Geraniaceae), Hibiscus rosa-sinensis, Hibicus syriacus (Malvaceae), and Cestrum nocturnum (Solanaceae) were investigated under controlled conditions (25 +/- 2A degrees C, 60 A +/- 10% R.H., and 16 h photophase). Life table data were analyzed by using an age-stage two-sex life table. The shortest total immature developmental time of females and males for P. madeirensis was obtained on C. nocturnum (20.42 and 21.90 days, respectively). The highest fecundities were 233 and 232 eggs on C. nocturnum and H. syriacus, respectively. The intrinsic rate of increase (raEuro dagger aEuro parts per thousand= 0.1511 day(-1)) and finite rate of increase (lambda aEuro dagger aEuro parts per thousand= aEuro dagger 1.1631 day(-1)) were the greatest when mealybugs were reared on C. nocturnum. Net reproductive rate (R (0)aEuro dagger aEuro parts per thousand= aEuro dagger 129.5 offspring) was the greatest when reared on H. syriacus, but this value was not statistically different from that on C. nocturnum. The shortest mean generation time (TaEuro dagger aEuro parts per thousand= aEuro dagger 31.3 days) was calculated on C. nocturnum. These results indicate that C. nocturnum and H. syriacus are more suitable hosts than H. rosa-sinensis and P. zonale for P. madeirensis.
