Study on Laboratory Population Parameters of Carmine Spider Mite(Tetranychus cinnabarinus) Infesting Mulberry YU71-1

The laboratory population parameters of carmine spider mite (Tetranychus cinnabarinus) on mulberry Yu 71-1 were studied using Jackknife techniques. The survival population was analyzed with Weibull model under (26±1) ℃,RH 85%,16L∶8D. The fertility life table parameters were as follows: r_m=0.344 2±0.004 1,R_0=40.501 5±2.584 0,λ=1.410 8±0.005 8, T=10.759 8±0.118 2,DT=2.013 5±0.024 1. The population survival curve belongs to type of Deevey Ⅰ.
