Life Table for Experimental Populations of Chrysopa formosa Brauer at Different Temperatures
摘要
Abstract
Life table for the experimental populations of Chrysopa formosa Brauer was established at different temperatures of 24,26,28,30,32 ℃,and the effects of temperature on the development and multiply of C.formosa Brauer were studied.The results showed that the threshold temperatures for the stage of egg,larva,pupa,adult and a generation of the C.formosa Braner was 9.22,7.47,8.69,7.04,7.52 ℃,respectively and the effective cumulative temperatures was 72.40 degree-day,302.21 degree-day,240.86 degree-day,140.49 degree-day,793.16 degree-day,respectively.The developmental rate increased with the temperature from 24 to 32 ℃.The development rate of C.formosa Brauer and temperature was significantly correlated.The innate capacity of natural increase (rm) was higher than zero,the population trend index (Ⅰ) was higher than 1.The experimental population of C.formosa Brauer increased at the temperatures from 24 ℃ to 32 ℃.The innate capacity of natural increase (rm) and population trend index (Ⅰ) of C.formosa Brauer was 0.095 0,0.116 3,0.113 9 and 48.363 5,66.610 0,48.069 3 at 26,28,30 ℃.The suitable temperatures for the development of C.formosa Brauer was between 26～30 ℃.关键词
