Acorns of the two deciduous oaks, Querucus serrata and Q. acutissima, were collected from four secondaty forests in Kanagawa in late autumn, 1994. Curculio dentipes was dominant over C. robustus in acorn of Q. acutissima, and utilized acorn of Querucus serrata monopolistically. Differences in utilization of acorn as food resources were discussed. Parasitic rate decreased at good harvest. It suggested that mast seeding of the oaks functioned effectively as the escape from Curculio beetles.
