Abstract: This study has been conducted to determine some biological parameters of the Phenacoccus madeirensis Green (Hemiptera: Pseudococcidae) on four vegetable plants (7 different varieties); tomato (Hazera and Torry) ( Solanum lycopersicum L.), eggplant (Adana Topağı and Anamur) ( Solanum melongena L.), pepper (Safran and Zafer) ( Capsicum annuum L.), and Pepino (Minski) ( Solanum muricatum L.). Experiments were carried out in climate cabinets at 25 ± 2 °C, 60 ± 10% R.H., and 16L: 8D) in Plant Protection Department Nedim UYGUN Biological Control Laboratory of Agriculture Faculty, Çukurova University between 2017 and 2018. Life table data were analyzed by using an age-stage two-sex life table computer program. According to results of this study, P. madeirensis completed its life cycle on eggplant, tomato, pepper and pepino. However, eggplant has been determined as the most suitable host plant for P. madeirensis during this study and the highest values of life table parameters were obtained from eggplant (R0 = 99.14 nymphs/ female, r = 0.147 d - 1 , λ = 1.159 d - 1, GRR = 289.49 nymphs/female). Consequently, this invasive pest could potentially cause economic losses in vegetable crops.
