The temperature-dependent development of Poinsettia thrips, Echinothrips americanus was studied at eight constant temperatures (15.0, 17.5, 20.0, 22.5, 25.0, 27.5, 30.0, and 32.5±1°C), 65±5% RH and photoperiod of 16L : 8D conditions. The developmental stages were divided into egg, 1st instar, 2nd instar, pre-pupa, pupa, and adult. The total developmental time in the immature stage was 40.4 days at 15.0°C and 11.6 days at 30.0°C, and it decreased with increasing temperature. The lowest temperature of the whole immature period was 10.7°C, and the cumulative temperature to complete the entire immature period was 217.4 degree days. The optimal development temperature (Topt) for the whole immature stage was estimated to be in the range of 30.51-31.21°C. Topt for each immature stage was 31.64-35.47°C at egg, 30.02-33.08°C at 1st instar, 29.16- 34.43°C at 2nd instar, 27.63-29.21°C at pre-pupa, and 29.81-30.12°C at pupa. In the analysis of the six non-linear models, Logan 6 model was the most appropriate as Zi (Weighting Factors) was 0.18.
