The spatial distribution of three species of stink bugs, Coptosoma punctatissimun, Piezodorus hybneri and Riptortus clavatus was analyzed using nine years of data from a soybean field. The goodness of fit test for POISSON distribution revealed that the adult and nymph of C. punctatissimun, the egg and nymph of R. clavatus and the nymph of P. hybneri showed an aggregated distribution, and that P. hybn.eri adults and the egg masses of C. punctatissimun also showed POISSON distribution at low population densities. Among these populations showing aggregated distribution, the R. clavatus egg had approximately negative binomial distribution, and the other populations had the NEYMAN'S type A distribution. The C_A index showed that P, hybneri nymphs and R. clavatus eggs were higllly aggregated. The m-m regression showed that the egg and the nymph of R. clavatus and the adult and the egg mass of C. punctatissimun were distributed as colonies. The index of spatial correlation (ω) showed negative association between the adult and the egg in P. hybn, eri and R. clavatus, and between the nymph and the egg in R. clavatus, but showed positive association between all other pairs of the other stages in stink bugs.
