ABSTRACT：The fruit flyDrosophila simulans Sturtrvantisa global pest that damages many economically important fruit crops. In recent years，it has caused severe outbreaks in the waxberry-producing regions of Wuxi City，Jiangsu Province. To clarify the effect of different temperature on the growth，development，and reproduction of D . simulans，we measured developmentalduration，survival rate，lifespan，fecundityand population growth parameters under five constanttemperatures（i.e.，19，22，25，28，and 31∘C ）. We found that the developmental duration of each life stage was shortened as the temperature increased within the 19-31∘C range. At 25°C ，the survival rate，lifespan of both sexes，total egg production by females，and net reproductive rate were maximized. In contrast，at 19°C ，the net reproductive rate，intrinsic growth rate，and finite growth rate were at their lowest. ，compared to the control temperature of 25°C ，pupal survivalrate，femalelifespan，andegg productionallsignificantlydeclined.Thisstudyhighlights thesignificantinfluence of temperature on the growth，development，and reproduction of D . simulans， providing a theoretical foundation for pest forecasting and integrated management strategies.
