“…The total foraging duration was 10 hours per day and the average duration of foraging trip was found to be 4.5 ± 0.146 min ( Table 1). The present findings were in proximity with the views of Singh et al (2000), Verma and Partap (1994) and Joshi (2000) where they made similar observations on initiation, cessation and duration of honeybee (Apis cerana) foraging activity on Brassica juncea.…”

This paper presents the findings of two studies - one conducted on foraging behaviour of Himalayan honeybee (Apis cerana F.) on flowering buckwheat (Fagopyrum esculentum Moench) in November 2001 to 2002 and another on its impact on the grain quality and yield increment of this crop conducted during 2000-2002 under different pollination treatments at Kirtipur, Kathmandu valley. Apis cerana bees started their foraging activities early in the morning (06.14 ± 0.004) and ceased late in the evening (17.28 ± 0.011). Total duration of foraging activity was 10:00 h and the average duration of foraging trip was 4.5 ± 0.14 min. Two peaks of foraging activities were observed between 08.30 to 10.30 (Peak I) and 11.30 to 13.30 O' clock (Peak II). The peak I period was the main foraging period and peak II was the second foraging period, both were very useful from the pollination point of view. After this, Apis cerana activity slowly diminished to a stand still at 17.30 pm. The time spent by Apis cerana on the buckwheat inflorescence at different hours of the day 09.00, 12.00, 15.00 O' clock showed longest (24 ± 3 min) in the morning and it decreased as the afternoon approached. This study revealed that Apis cerana bee pollination increased grain set in terms of the total number of grains per plant (169.76 ± 4.10), grain weight (33.03 ± 0.26 g) and grain yield (4.40 ± 0.12 g). It also increased the value of fertility (16.08 ± 0.21) and harvest index (35.32 ± 0.35) when compared with Control pollination/excluding all the insects (CP) and Open pollination (OP) treatment. This is mainly due to greater number of pollinators in the Bee pollination (BP) treatment, their longer duration of foraging and also due to superior pollinating efficiency of Apis cerana bees.

“…Concerning times of observation, the intensity of visitation of both bee species was at the maximum number at 11.00 am -1.00 pm all over the observed weeks and at both cultivars and planting dates, followed by the time at 9.00 -11.00 am with significant differences. These results are in agreement with Verma and Partap (2010), Verma, and Phogat (1994), Verma, and Joshi (1983) who found that peak foraging activity of A. cerana on cauliflower and cabbage was between 11.00 am and 13.00 pm for each crop.…”

Field experiment was conducted in 2011-2012 to study the impact of genotype, planting date, and inflorescence type on bee abundance and seed production of broccoli in Ismailia Governorate. The abundance of two selected bee species, Apis mellifera L. and Colletes lacunatus Dours was estimated on two cultivars of broccoli, Sultan and Marathon in two different planting dates and two types of inflorescences (primary and secondary). Results indicated that both A. mellifera and C. lacunatus significantly increased the pollination percentage. Bee abundance was significantly at the maximum level at 11.00 am-1.00 pm, all over the weeks of observation, followed by the previous time of observation, at 9.00-11.00 am, then decreased significantly at 1.00-3.00 pm to reach the lowest abundance 3.00-5.00 pm. Also, results indicated that C. lacunatus was the dominant pollinator and had more intensity visitation than A. mellifera on the both cultivars. Generally, Marathon tends to give more fruit number and weight and accordingly more seeds of light weight. On the other hand, Sultan has a tendency to give less seed number of heavier weight. The primary inflorescence gave less number of flowers and consequently less number of fruits than secondary inflorescence, but those fewer fruits gave less number of seeds with heavier weight. The effect of planting density on seed production was due to differences in number and destination of transported pollen grains. Planting date showed a profound influence on the potential of seed yield. This study demonstrated that bee pollination could significantly improve both the yield and the quality of seeds in broccoli under Ismailia conditions.

“…It observed that the time spent on the flowers by A. dorsata was more during midday hours of the day. This agree with the previous results recorded by [24] who reported that different insect visitants are generally forage on the flowers between 0900 through 1200 hrs of the day.…”
