Coffee leaf miner <i>Leucoptera</i> coffeella (Guérin-Mèneville, 1842) (Lepidoptera: Lyonetiidae) it is a one biggest insect pest of coffee in American continent coffee plantations, due to its generalized occurrence, since all coffee varieties are susceptible to attack, and the economic damage caused, which can involve production losses up to 50%. The present study investigated biological aspects, including the fertility life table and the ideal conditions for reproduction and development of this pest, at 7 constant temperatures (18, 22, 25, 28, 30, 32, 35°C) under laboratory conditions. The results showed that the mean biological development time of <i>L. coffeella</i> was affected by temperature, completing its life cycle more rapidly in increased temperatures until the 32°C, but low survivor of all <i>L. coffeella</i> stages was observed from 30°C. The preoviposition period decreased with increasing temperatures, the total fecundity was significantly affected by the temperature and the longevities of males and females were affected by the temperature. The highest net reproductive rate (22.23), finite rate of increase (0.15) and viability were observed at 28°C, indicating that this temperature was the most suitable for development. The information obtained can be used in integrated pest management programs, to forecast <i>L. coffeella</i> outbreaks and population growth, and to study the behavior of this insect under different climate conditions
