Abstract: The development duration and survival ratio of Coleosoma octomaculatum under 6 differenttemperatures are determined.Its development rate coordinates with Logistic curve.The mini-mum temperature for development in egg and spiderling stages is calculated as 9.76℃ and9.26℃ respectively.The relationship between survival ratio and temperature coordinates withporabola curve,with the highest generation survival ratio of 78.2% at 29℃.Based on abovedata,a life table of C. octomaculatum experimental population is established,which showsthat the growth index of the population is the highest at 23℃.
