Investigations were made on the edge effects on ambrosia beetleassemblages in Pasoh Forest Reserve, a lowland rain forest in Peninsular Malaysia, which largely borders oil palm plantations (Elaeis guineensis) established in the 1970s. Species richness and composition of the ambrosia beetles (Scolytidae: Xyleborini)sampled with ethanol traps were not considerably changed along a gradient from the core area to the boundary of the forest. However, a polyphagous species, Xylosandrus crassiusculus, consistently increased in number from the core to the forestedge, being super-dominant at the boundary. It was as abundant at the surrounding oil palm plantation as in the forest boundary, consistent with the hypothesis that there is a large influx of X. crassiusculus from oil palm plantation to forest reserve. Thepopulation may also, to a lesser extent, be enhanced by forest disturbance at the margin of the reserve.
