• A comparative study of pre- and post-dispersal damage to the acorns of two oaks, Quercus serrata Thunb. and Q. mongolica Fischer, was done over 3 years in a species-rich deciduous forest in central Japan. The numbers of acorns bored into by moth larvaeand by Kobuzo rectirostris (Roelofs) was low and relatively uniform each year for both oak species, but the numbers bored into byCurculio spp. varied from year to year. The proportions of acorns attacked were independent of the density of acorns produced forboth oak species. The proportions of the dispersed acorns of both oak species on the forest floor that disappeared bctweenautumn and spring were less than 27%, .and were lower for species in the stand that belong to family Fagaceae. However, by the nextsummer, most dispersed sound acorns had been infested by moths that specialized on post-dispersal acorns.
