Abstract:
Meagcopta cribraria(Hemiptera：Pentatomidae) has become a destructive pest on the soybean crop in eastern China.In order to accurately estimate the pest population based on a sound sampling design，the all-count method and the five-point sampling method were used to survey eggs，nymphs and adults during early pod-setting stage of soybean.Frequency distributions were tested for the fit of statistical distribution models，and several indices of dispersion were used to measure the spatial pattern.The results showed that spatial distributions of the egg，nymph and adult belonged to the negative binomial，which indicated the clumping distribution of individuals at different life stages of Meagcopta cribraria in the soybean field.
