Abstract: In order to reveal the effects of temperature on the growth and development of Aglossa dimidiata  parasitized on Litsea coreana, a laboratory experiment was conducted to study the mean development duration, development rate, and survival rate of A. dimidiata at its different growth stages at 31 ℃, 28 ℃, 25 ℃, 22 ℃, and 19 ℃, with the development threshold temperature and effective accumulated temperature for different growth stages calculated. Temperature had significant effects on the developmental duration. Except that the development duration of egg was shortened with increasing temperature, the development durations of larva, pupa, and immature A. dimidiata were the shortest at 25 ℃, being 249.53±23.83, 12.94±1.27, and 273.00±24.19 days, respectively. There existed significant relationships between the development rates of A. dimidiata at its different growth stages and temperature, with positive linear relationship at egg stage, and quadratic relationship at larva, pupa, and immature stages. Temperature also had significant effects on the survival rate of A. dimidiata. The survival rates of A. dimidiata at its different growth stages were all the highest at 25 ℃, being 94.0%, 73.8%, 91.3%, and 63.4% for the egg, larva, pupa, and immature A. dimidiata, respectively, followed by at 22 ℃ and 19 ℃, and the lowest at 31 ℃. No larva and pupa could survive at 31 ℃, suggesting that A. dimidiata was not resistant to high temperature. The development threshold temperature for egg, larva, pupa, and immature A. dimidiata was 13.21 ℃, 17.12 ℃, 14.76 ℃, and 16.47 ℃, and the effective accumulated temperature was 117.94, 870.88, 149.70, and 1442.75 daydegree, respectively. The results coincided with the fact that the A. dimidiata  reproduced 2 or 3 generations a year in Xifeng area of Guizhou, Southwest China.
