[Objectives]  To investigate the effects of different temperatures on the growth, development, and reproduction of the green stink bug Nezara viridula (Linnaeus) in order to provide a theoretical basis for the monitoring and ecological management of this pest. [Methods]  Green stink bugs were reared for more than two generations before being placed in incubators set at different temperatures (18, 20, 23, 26, 28, 30 ℃) to observe their daily survival, mating and oviposition rates. The survival rates, development duration, effective accumulated temperature, and fecundity, of each temperature treatment group were measured and compared. [Results]  The threshold temperatures of the egg, 1st instar, 2nd instar, 3rd instar, 4th instar, 5th instar, nymphs, pre-mature and pre-oviposition, stages were 13.17, 13.88, 14.13, 14.15, 10.15, 10.96, 16.37, 10.53 and 11.24 ℃, respectively. Within a certain temperature range, an increase in temperature shortened the duration of each developmental stage. The duration of a single generation was shortest (68.25 d) at 28 ℃. The longest duration of a generation, 141.00 d, was recorded at 20 ℃. Adults emerged at all temperatures, but emergence rates at 18 ℃ and 30 ℃ (1.18% and 1.43%, respectively) were significantly lower than at the other four temperatures. The highest mating and oviposition frequencies were recorded at 23 ℃ and 26 ℃, respectively. The highest innate capacity for increase (0.078) was recorded at 26 ℃. The proportion of emerged adults was highest at 20 ℃, and the highest reproductive rate was recorded at 26 ℃. The highest average number of eggs laid per female (172.3) was recorded at 26 ℃, whereas the lowest (80) was recorded at 28 ℃. Temperature affected adult body color. The proportion of the all-green phenotype was lowest (30.86%) at 20 ℃ and highest (82.98%) at 28 ℃. [Conclusion]  Higher temperatures accelerate the development of the green stink bug and shorten its generation time. Low temperatures are more suitable for the growth of the green stink bug but higher temperatures are more suitable for its reproduction.
