A pollen atlas for 55 species of flowers frequently visited by Apis cerana has been prepared.
Photomicrographs of 55 species (Table 19 ) of the pollen of Malaysian bee plants that provide both nectar and/or pollen for Apis cerana were prepared and will form the basis for the pollen atlas that is planned for publication in the coming year.

The male flowers of Elaeis guineensis (African oil palm) are visited by bees for their pollen but the female flowers are not. Furthermore, oil palm trees are wind-pollinated and neither of the flowers produces nectar (Agwu, 1985). Elaeis guineensis therefore serves the bees as a major source of pollen meal (but not of nectar).
