In mango (Mangifera indica L. cv. Carabao), the efficiency of insect pollinators such as Trigona biroi Friese, honeybees (Apis cerana Fabricus and Apis mellifera Linn.), and flies (Chrysomya sp. and Eristalis sp.) was compared at Opina's Mango farm in Barangay [village] Sirang-Lupa, Calamba City, Laguna [Philippines] from 3 Nov 2006 to 10 Apr 2007. The relative abundance and foraging behavior of insect pollinators was also documented. Some aspects of the floral biology of mango were observed as if influenced pollinator foraging. A total of 21 insect species belonging to five orders visited mango flowers. The primary pollinators were sting less bees (Trigona biroi), calliphorids (Chrysomya spp.), syrphids (Eristalis spp.) and honey bees (Apis cerana and A. mellifera). Pollinators actively foraged from 700-1059 h, with the peak period occurring at 800-859 h. The foraging activities of the pollinators synchronized with anthesis. Prior to the introduction of bee colonies in the mango farm, the fruit set in caged (2.13%) and uncaged (3.34%) inflorescences did not vary. After the introduction of bee colonies, the fruit set in uncaged inflorescence (41%) was significantly higher than that in the caged inflorescence (0.7%). The terminal inflorescence, floral longevity (5d) and scent, and sticky pollen provided enabling conditions for insect pollination
