Abstract
To clear the Chrysopasinica Tjeder control effect on Aphis glycines .3-Instar Chrysopasinica Tjede larvae functional response of A phis glycines was tested ,indicating that the functional response was holling Ⅱtype disc equation ,through the χ2 testing ,the difference between theoretical and observation were not signifi-cant .Chrysopa sinica Tjeder on A phis glycines holling Ⅱ functional response equation was :Na= 0 .659 3 NT/(1+0 .659 3 × 0 .004 3 N) ,(R=0 .994 2 ,P<0 .01) ,calculating the maximum amount of predation were 230 .088 0 A phis glycines each day ,interference of its own density on predation Hassell-Varley equation was :E=0 .383 6 P-0 .602 3 ,search factor Q=0 .383 6 ,interference coefficient m=0 .602 3 .关键词
