Flower thrips, Frankliniella intonsa, is one of the most important agricultural pests that can transmit tospoviruses. In this research life table parameters of F. intonsa was studied in the presence and absence of Tomato spotted wilt virus under laboratory conditions (25±2°C, 65±5% RH and 14:10 h L: D photoperiod) based on the age-stage, two-sex life table. Based on the results, viruliferus F. intonsa had not significantly different in egg, L1, L2, pre pupa, pupa and total pre adult longevity compared to unexposed one. In non viruliferus F. intonsa, intrinsic rate of increase (rm), Net reproduction rate (R0), Mean generation time (T), Finite rate of increase(λ) and Gross reproduction rate (GRR) were 0.1068 day-1, 17.22 offspring per individual, 26.65 day, 1.11 day-1 and 26.17 offspring per individual, respectively. In viruliferus F. intonsa, intrinsic rate of increase (rm), Net reproduction rate (R0), Mean generation time (T), Finite rate of increase (λ) and Gross reproduction rate (GRR) were 0.107 day-1, 18.13 offspring per individual, 27.02 day, 1.1145 day-1 and 30.57 offspring per individual, respectively. According to our results, no statistically significant differences were seen between viruliferus and non viruliferus individuals.
