| Abstract: | With the method of
distribution pattern index, it was abserved that the distribution of the second generation
Helicoverpa armigera Hbner's eggs in peanut field belongs to common negative binomial form,
and social intensity changes with population density. The models of theortical sample and
sequential sample were formulated: n =172.41/ x(-4/5 -27.12 and T0( N )=0.9 N 2.31 N
respectively. The relationship between the stubble rate of bearing eggs (P) and egg's density (
xDD(-4/5 ) is following: x-4/5 =1.4999-ln(1- p )1.0916 |
