The foraging behaviour and pollination efficiency of floral visitors on Egyptian clover, Trifolium
alexandrinum was conducted at Forage Section, Department of Genetics and Plant Breeding, CCS, Haryana
Agricultural University, Hisar during 2012 and 2013. The maximum foraging rate was recorded in N+P
(nectar+pollen) foragers of Apis dorsata (7.2 flowers/min.), P (pollen) forager of Apis florea (7.2) and Apis
mellifera (7.1) followed by pollen (6.3), least in nectar forager of A. dorsata (5.1) and A. mellifera (5.5). The
maximum foraging speed was recorded in nectar forager A. dorsata (22.4 seconds/flower) followed by its
pollen foragers (19.0). The A. mellifera foragers were recorded with minimum foraging speed for nectar+pollen
(4.6 seconds/flower), pollen (4.9) and nectar (7.4). The larger bodied A. dorsata carried the maximum loose
pollen grains (LPG) on their body (79,625) while the smallest species A. florea had minimum capacity (36,375)
and the medium sized A. mellifera was recorded with intermediate capacity (73,250). On the basis of relative
pollination efficiency (RPE), A. dorsata was the most efficient pollinators (16.4) of T. alexandrinum flowers
followed by the pollen foragers (13.3).
