In this study, egg hatching and larval development of Paranura rosea were experimented at different temperature conditions. The development was studied at four different temperatures, ranging from 15 to 30℃ (in 5℃ intervals), under a dark. As a result, the egg hatching time decreased from 21.67±1.99 to 6.57±1.96 days as the temperature increased from 15 to 30℃. The highest egg hatching rate was 49.27±20.69% at 25℃, where as the lowest rate was 27.97±23.06% at 15℃. The developmental rate increased gradually with temperatures from 15 to 30℃, and the developmental rate was highest at 30℃. The survival rate was highest at 15℃ (85.27 %) and lowest at 30℃ (57.53 %). This wide thermal adaptation in egg hatching and larval development of Paranura rosea is advantageous for various environmental sudies, such as toxicity tests.
