Studies conducted in 1985 indicated that clones RRIM 701, RRIM 600 and PR 255 were potential sources of nectar for bees. In all the clones, nectar was available for about one month with the peaks of flow occurring during the second and third weeks of March. The volume of nectar flow of the clones was highly negatively correlated with rainfall. There was no correlation between the volume of nectar and its sugar content, suggesting no preference for any clone by nectar foraging Apis cerana. The formation of honey cells, brood cells, pollen cells and new honeycomb cells were interrelated. Correlations between brood, pollen, honey and newcomb cells were significantly high in RRIM 701 but there were no correlations between the various cells with RRIM 600 and PR 255. The potential of clones limiting the activities of bees and the bee-keepers were discussed. Honey production among clones studied was not significantly different. A total of 2.97 kg, 2.13 kg and 1.73 kg of honey per hive was harvested from bee hives under RRIM 701, RRIM 600 and PR 255 respectively. The weight of honey harvested was similar to the ranking of nectar flow. Various limitations of bee-keeping under rubber were highlighted and some management strategies outlined
