Pollination ecology of three Durio species, D. grandiflorus, D. oblongus, and D. kutejensis (Bombacaceae), was studied in a lowland dipterocarp forest in Sarawak, Malaysia, during a peak flowering period when at least 305 species of plants bloomed in 1996. Durio has been reported to be pollinated by bats in Peninsular Malaysia. However, my observations of flower visitors and pollination experiments indicated that two species, D. grandiflorus and D. oblongus, were pollinated by spiderhunters (Nectariniidae) and that the other species, D. kutejensis, was pollinated by giant honey bees and bats as well as birds. Hand-pollination experiments showed that all three species were obligate outbreeders. A resource limitation in fruit production was suggested. The former two species were visited only by spiderhunters, and the bagged flowers that were opened for animal visitors only at night bore no fruit, while those that were opened only during the day bore fruits, at comparable fruiting ratios to open pollination. Durio kutejensis was observed to be visited by giant honey bees, birds, and bats at different times of day, and three series of bagged experiments that exposed the flowers to animal visitors at different times of day bore fruits at a comparable ratio to open-pollination.
在马来西亚沙捞越的低地热带雨林中，对三种榴梿属植物（榴梿、榴梿和榴梿）的传粉生态学进行了研究，该地区在 1996 年的盛花期至少有 305 种植物开花。在马来半岛，榴梿被报道为蝙蝠传粉。然而，我对花访客的观察和传粉实验表明，两种植物，榴梿和榴梿，是由蜘蛛鸟（花蜜鸟科）传粉的，而另一种植物，榴梿，也是由巨型蜜蜂、蝙蝠以及鸟类传粉的。人工授粉实验表明，这三个物种都是严格的异花授粉者。这表明存在果实生产的资源限制。前两种植物只被蜘蛛鸟访问，而那些只在夜间为动物访客开放的套袋花朵没有结果实，而那些只在白天开放的花朵则结出果实，与开放授粉的结果比例相当。榴梿被观察到在不同的时间被巨型蜜蜂、鸟类和蝙蝠访问，三个系列的套袋实验将花朵暴露在不同时间的动物访客中，结果与开放授粉的果实比例相当。
