Rambutan percent, but a high abortion level contributes to a much lower level of production at harvest (1 to 3 percent). The fruit matures 15–18 weeks after flowering. Rambutan cultivation in Sri Lanka mainly consists of small home gardens. Malwana, a village in the Kelani River Valley, is popular for its rambutan orchards. Their production comes to market in May, June, and July, when it is very common to observe seasonal traders along the streets of Colombo. Sri Lanka also has some off-season rambutan production in January and February in areas such as Bibile, Medagama, and Monaragala. Both male and female

Among the Diptera, "Lucilia" spp. are abundant, and among the Hymenoptera, honey bees ("Apis dorsata" and "A. cerana") and the stingless bee genus "Trigona" are the major visitors. "A. cerana" colonies foraging on rambutan flowers produce large quantities of honey. Bees foraging for nectar routinely contact the stigma of male flowers and gather significant quantities of the sticky pollen from male blossoms. Little pollen has been seen on bees foraging female flowers. Although male flowers open at 06:00, foraging by "A. cerana" is
