Effect of Temperature on Experimental Population Dynamics of Typhlodro mus bambusae Ehara

Abstract: The development,survivorship,fecundity and longevity of Typhlodromus bambusae Ehara fed on the spider mite of Schizotetranychus bambusae were observed at 16,20,24,28,and 32 ℃,respectively.The age-specific life tables of experimental population in T.bambusae were established.The relationship bet ween population dynamics and 5 constant temperatures was analyzed using Morris model and Weibull frequency distribution.The results indicated that the eggs lai d per female varied greatly from 31.26 at 24 ℃ to 9.2 at 32 ℃.The relationship between population trend index (I) and temperature (T) could be si mulated with equation:I=98.7747+9.6914T-0.2033T[2].Theoretically,I had the highest value (16.74) at 23.83 ℃.Based on analysis,the mos t important factor affecting I was average eggs per female.Within temperature range of 16-32 ℃,The population survival curve belongs to type of Deevey Ⅰ.
