Natural oak regeneration is poor in Missouri's oak-hickory forests. The potential of the Asiatic oak weevil,Cyrtepistomus castaneus(Roelofs), to affect Missouri's oak resource was addressed. The spatial dispersion and density of the adult Asiatic oak weevil was investigated in a Missouri oak-hickory forest in relationship to the density of oaks, the preferential food source of this insect. The spatial dispersion pattern of emerging adult weevils was contagious and was defined by the negative binomial distribution in five of nine trapping areas. Oak stem densities within the trapping area of each plot were positively correlated with Asiatic oak weevil emergence density estimates in 1985. In 1986, Asiatic oak weevil catches in individual traps were not correlated with oak stem density associated with each trap when traps were placed 3 m apart. However, Asiatic oak weevil catches were significantly correlated with oak stem density associated with individual traps when traps were placed 30 m apart. Cluster analysis of the vegetation associated with individual traps in 1986 revealed the vegetation to be homogeneous in the area where the traps were placed 3 m apart and the vegetation to be more heterogeneous when traps were placed 30 m apart.
