Effect of Photoperiod and Temperature on the Life Table Parameters of Onion Thrips (<i>Thrips tabaci</i>) Lineages

Abstract This study investigated the effect of photoperiod and temperature on bionomics three Thrips tabaci lineages (L1 L2 – leek-associated, T tobacco-associated). The experiment was performed in laboratory under following conditions: 23 °C 16L/8D 8L/16D, 15 8L/16D. Reproductive diapause detected lineage at but not L1 lineages, while all diapaused Adult longevity L1, L2, were 29.51, 25.69, 29.76, respectively, 16L/8D; 30.9, 28.52, 38.06, 8L/16D; 48.9, 34.22, 76.89 days, °C. Mean fecundity 89.30, 80.31, 86.76, 40.14, 46.94, 39.34, 7.0, 13.85, 17.87, difference responses to could be a factor cause sympatric population variation different T. same environmental condition.
