Abstract
Foraging behavior of the giant honey bee, Apis dorsata F. (Hymenoptera: Apidae) in sunflower (Helianthus annuus L.) at Peshawar District of Pakistan
Highlights
Introduction prospects of cropsIn terms of pollination, Insect visitors pollinate more or less 90% of many plant species are generalists [2, 3] and various flowering plant species across the rely on numerous pollinator species
The following parameter was studied during experiment: Population density of Apis dorsata on sunflower Hysun-33 As per procedure adopted by [16] observation on bee visits to sunflower blossoms was taken from commencement of 5 per cent flowering on the crop and last until 35th days after inflorescence
Foraging activity of Apis dorsata on sunflower Hysun-33 during spring 201213 Data on foraging behavior/ pattern of honeybees on selected crop at different time intervals revealed that 5 days after initiation of flowers on the crop, it was found that individuals (4.37) of A. dorsata were most active during noon at 1600 hr, which was followed by second peak (3.62) of foraging activities at 1200 hrs
Summary
Introduction prospects of cropsIn terms of pollination, Insect visitors pollinate more or less 90% of many plant species are generalists [2, 3] and various flowering plant species across the rely on numerous pollinator species. Results Foraging activity of Apis dorsata on sunflower Hysun-33 during spring 201213 Data on foraging behavior/ pattern of honeybees on selected crop at different time intervals revealed that 5 days after initiation of flowers on the crop, it was found that individuals (4.37) of A. dorsata were most active during noon at 1600 hr, which was followed by second peak (3.62) of foraging activities at 1200 hrs. On 20th day of 5 per cent of flowering on the crop, A. dorsata individuals foraging activities were observed with 5.25 bees per 3 m2 area for 5 minutes at 1600 hr that was followed by 5.25 and 4.62 count of bee visitants at 1200 and 1000 hr respectively. On 10th day after flowering, A. dorsata foraging activities were observed with highest count of 3.25 bees per 3 m2 area for 5 minutes at 1600 hrs of the, which was further followed by a mean population of 3.00 bees at 1200 hr. On 25th day after crop, blooming stage maximum foraging recorded at 1600 hr with mean number of 4.25 bees, which was followed by a second peak of
