The Hawaiian flower thrips, Thrips hawaiiensis (Morgan), a common flower-inhabiting thrip, is now a potential pest globally. Effective control of T. hawaiiensis requires information about the effects of temperature on its ontogeny and population growth. In this study, the life history characteristics and demography of T. hawaiiensis were defined at eight temperatures (9–35°C). Additionally, the thermal constant and temperature threshold were estimated by regression analysis. The developmental duration and longevity of T. hawaiiensis decreased with an increase in temperature between 16°C and 32°C; females survived for longer than males at all temperatures. The lower temperature threshold and thermal constant of preadult T. hawaiiensis were 10.5°C and 132.5 degree-days, respectively. The oviposition days of the females gradually decreased from 16°C to 32°C, and net maternity was higher at 20°C than at 16°C, even though the same number of eggs were laid at both temperatures. The mean longevities of the populations were greatest at 20°C; the life expectancy and reproductive value decreased with temperature. The intrinsic rate of increase and finite rate of increase were significantly highest at 20°C, 25°C, and 30°C. Population growth was triggered at 12.3°C, and reached a peak at approximately 27°C when it proliferated to the largest population size. Therefore, the results suggest that although the population of T. hawaiiensis starts to grow at lower temperatures, it adapts to a wide range of temperatures, and these findings facilitate prediction of different stages of damage, population size, and seasonal occurrence of T. hawaiiensis.

夏威夷蓟马（缨翅目：蓟马科）的温度依赖性人口学：对预防和控制的意义

夏威夷花蓟马（Thrips hawaiiensis (Morgan)）是一种常见的花栖蓟马，现已成为全球潜在的害虫。有效控制 T. hawaiiensis 需要有关温度对其个体发育和种群增长影响的信息。在这项研究中，T. hawaiiensis 的生活史特征和人口统计学定义在八个温度（9-35°C）下。此外，通过回归分析估计了热常数和温度阈值。T. hawaiiensis 的发育持续时间和寿命随着温度在 16°C 和 32°C 之间的升高而降低；在所有温度下，雌性比雄性存活的时间更长。成体前的夏威夷T. hawaiiensis的下限温度阈值和热常数分别为10.5°C和132.5°-days。雌性的产卵天数从 16°C 逐渐减少到 32°C，尽管在两种温度下产卵的数量相同，但 20°C 时的净生育率高于 16°C 时。种群的平均寿命在 20°C 时最长；寿命和繁殖价值随温度而降低。内在增长率和有限增长率在 20°C、25°C 和 30°C 时显着最高。人口增长在 12.3°C 时触发，并在大约 27°C 时达到峰值，当它增殖到最大的人口规模时。因此，结果表明，虽然夏威夷锥虫的种群在较低温度下开始生长，但它适应的温度范围很广，这些发现有助于预测不同的损害阶段、种群规模和季节性发生的锥虫。
