1996年在马来西亚沙捞越的一个低地龙脑香林中，利用林冠观测系统研究了一种挺水树种-龙脑香科小叶香树（Shorea（Section Mutica）parvifolia）的花粉生态学。虽然在马来西亚半岛有报道称该物种由蓟马授粉，但我们对访花者的观察和授粉实验表明，甲虫（鞘翅目，甲虫科和甲虫科）对该物种的授粉有贡献。沙捞越的一种植物。在扫网采集的访花昆虫中，甲虫占74%，携带花粉的甲虫占30%，而蓟马占16%，携带花粉的蓟马占12%。花瓣和花粉的顶端部分作为甲虫的奖励。蓟马到达后几乎一直呆在花里，花间的运动很少。结果表明，引进甲虫套袋花，但不引进蓟马。人工授粉试验和未处理、套袋和开放花坐果率的比较表明，S。parvifolia以远交为主。
Pollination ecology of an emergent tree species, Shorea (section Mutica) parvifolia (Dipterocarpaceae), was studied using the canopy observation system in a lowland dipterocarp forest in Sarawak, Malaysia, during a general flowering period in 1996. Although the species has been reported to be pollinated by thrips in Peninsular Malaysia, our observations of flower visitors and pollination experiments indicated that beetles (Chrysomelidae and Curculionidae, Coleoptera) contributed to pollination of S. parvifolia in Sarawak. Beetles accounted for 74% of the flower visitors collected by net-sweeping, and 30% of the beetles carried pollen, while thrips accounted for 16% of the visitors, and 12% of the thrips carried pollen. The apical parts of the petals and pollen served as a reward for the beetles. Thrips stayed inside the flower almost continuously after arrival, and movements among flowers were rare. Fruit set was significantly increased by introduction of beetles to bagged flowers, but not by introduction of thrips. Hand-pollination experiments and comparison of fruit set in untreated, bagged, and open flowers suggested that S. parvifolia was mainly outbreeding.
