PERANAN TUMBUHAN LIAR DALAM KONSERVASI SERANGGA PENYERBUK ORDO HYMENOPTERA

The role of the wild plants in relation to the conservation of the Indonesian insect pollinators was studied at several areas of Java. Three of direct observation methods were applied: study of biodiversity and observation on the wild flowers and the insect pollinators as well, and the behaviour of the insects. The flowers of wild plants were relatively smaller and paler in colour, however they were more attractive to insect pollinators than cultivated plants. Flowering time of the wild plants was mostly during wet seasons, contrary to that of the cultivated plants which was mostly during dry seasons. Our observation indicated that these wild plants are the food resources of insect pollinators during wet seasons. Observation data support the importance of wild plants to supply food to insect pollinatorsduring wet seasons. Management of wild and cultivated plant environments is necessary to conserve insect pollinators.
