Widhiono I, Sudiana E. 2015. The role of wild plants in the conservation of pollinating insects of the Order Hymenoptera. Pros Sem Nas Masy Biodiv Indon 1: 1586-1590. The diversity of pollinating insects is closely connected with the diversity of wild plants in nature as bee forage. The purpose of this study was to determine the role of wild plants as wild bee forage. This study was conducted in an area under the pine forest stands in northern slopes of Mount Slamet; survey method was done with purposive sampling technique. Parameters measured were the abundance and the species richness of bees visited wild plants as well as the number and species of wild plants visited by insects pollinators. The results showed that at study sites found 42 species of wild plants and 24 are visited by pollinating insects that consist of 10 species of wild bees, namely: Ceratina sp, Nomia melanderi, Hyaleus modestus, Megachile realtiva, Xylocopa latipes, Amegilla cingulata, A. romandi, Rhopalidia cingulata, R. zonata, and Lasioglosum leucozonium. Eight species of wild plant visited by more than one species of bee are: Cleome rutidosperma, Borreria laevicaulis, B. elegans, Euphorbia heterophyla, Rubus parviflorus, Salmo cantoniensis, Tridax procumbers, and Vero cinerea. Wild plants with the highest diversity (Shannon Index) of pollinating insects shows that Cleome rutidosperma has diversity index (H '= 2097, E = 0.9047), and the lowest in the Rubus parviflorus (H' = 0.5623, E = 0.8774). Insect pollinators most visited wild plants is Lasioglossum leucozonium visiting 13 species of wild plants. Based on the results of this study concluded that the eight wild plants that can contribute to the conservation of the diversity of wild bees.
