Floral visitors of McArthur's palm (Phychosperma macathuri (Wendl) ex Moore).
1994
Baguinon N.T. | Cervancia C.R.
The McArthur's palm flower is borne on a protandrous inflorescence. Male flowers open first and seven days after the last male flower opened, the female flowers open and present their pollen receptive stigma. In a clump of McArthur's palm, several axes may bloom either simultaneously as sequentially so that, at any given time, it is possible that male and female flowers may open at the same time, hence self pollination may be effected, or if not, then cross pollination is possible. Among the floral visitors, the stingless bee, Trigona biroi Friese and Apis cerana F. is the most important since they forage on both male and female flowers at equal intensity. This behavior contributes to their pollination efficiency. Other hymenopteran visitors were Vespa sp., Anthopora sp., and Sphecidae. Dipterans belonging to family Syrphidae, Tabanidae, Dolicopidae, and Calliphoridae were also observed.
