Pollen Loads

In May, July and September pollen loads samples were collected from 20 honeybee colonies, during 4 days at fixed hours. The pollen loads were classified into botanical taxons. Pollen loads of every examined taxon were collected during the whole day. The daily dynamics of pollen collection depends more on time of the day than temperature.

An experiment was conducted to determine the foraging behavior of Apis mellifera L. and Apis cerana F. in rapeseed under cage condition in Chitwan, Nepal during 2012-2013. This experiment showed that Apis cerana F. foraged extra 42 minute per day as compared to Apis mellifera L. Apis cerana F. were more attracted to nectar, whereas Apis mellifera L. were more attracted to pollen collection throughout the day. The activities, in into hives and out from hives, for both species were recorded more at 2:00 pm and least at 8:00 am. The highest in-out were observed at 2:00 pm on both species as Apis mellifera L. 44.33 bees entered into hives and 49.66 bees went out of hives, whereas lower number of Apis cerana F. 43.66 bees entered into hives and 48.16 bees were out of hives. Apis mellifera L. collect 1.22:1 and 0.41:1 pollen nectar ratio at 10:00 am and 4:00 am whereas at same hours Apis cerana collect 1.16:1 and 0.30:1 pollen nectar ratio. Apis cerana F. foraged significantly higher number of rapeseed flowers and plants as compared to Apis mellifera L. under caged condition. It shows that Apis cerana F. was more efficient pollinator as compared to Apis mellifera L. under caged condition.

Dose Dependent

AbstractWe investigated the effects of synthetic honey bee (Apis mellifera L.) queen mandibular gland pheromone on colony foraging and brood rearing. Colonies newly established in the spring showed a significant, dose-dependent increase in the number of foragers gathering pollen, and individual pollen foragers returned to the nest with larger pollen loads. These two effects combined resulted in a doubling of the amount of pollen brought into colonies by foraging bees. Brood rearing also increased, but not significantly. In contrast, large, established colonies showed no effects at their summer population peak. We conclude that queen mandibular pheromone can significantly affect foraging, but its effects depend on colony conditions and environmental factors.

Collection Period

Abstract The aim of our study was to investigate how the collection period affects and influences the production, chemical composition, and size of bee pollen loads (0.5, 1.0, 2.0, greater than 2.0 mm). The results showed there was a predominance of pollen loads with a diameter greater than 2.0 mm in all the production seasons. For all the seasons, there were no differences in protein content between the particle sizes. But when comparing 0.5 mm during the different periods, there were significant differences; the highest value was found during the winter (24.39 ± 3.7%). As far as lipids and crude fiber are concerned, we obtained differences between the same granulometry sizes for the spring and summer seasons. As for ashes, the results showed differences between different particle sizes for the summer and autumn seasons. Our results have shown that regardless of pollen particle size, its quality was not altered, suggesting that smaller loads can be commercially used by containing nutritional quality or else be used by beekeepers as a supplement during periods of food scarcity.

A study was carried out to investigate pollen foraging, storage and its impact on Apis mellifera L brood production throughout the year under Terai condition of Nepal in 2003-2005. Number of pollen foragers, amount of pollen stored as beebread and brood in the colony differed significantly during different seasons. Number of pollen foragers (117.5 bees/ hive/ 5 min) and amount of pollen as beebread (2439.0 gm/hive) and number of brood (14787.2 brood cells/hive) were the highest during spring season, while the lowest number of pollen foragers (38.1 bees/ hive/5 min.) stored the lowest amount of beebread or pollen store (152.5 gm /hive) and produced the lowest number of brood (3811.7 brood cells/ hive) and bees in rainy season. Autumn, winter and summer seasons were normal for pollen collection and brood production, while starvation and nutritional deficiencies due to the acute shortage of pollen in rainy season was the major reason to decline or collapse the bee population before the honey flow season. Therefore, feeding bees with adequate amount of nutritionally rich pollen during rainy season is essential to maintain a healthy and strong bee colony for the production of higher honey and other hive products.

This paper aims to identify the botanical origin of pollen loads collected by Apis mellifera L. in Canavieiras municipality, Bahia state. It provides a list of polliniferous plant species from the Atlantic Forest biome that are important for the development of regional apiculture. Using the acetolysis method, 35 bee-pollen samples were analyzed qualitatively and quantitatively. Results showed that pollen types Elaeis (23.99%), Mimosa pudica (22.78%) and Cecropia (13.68%) were the most abundant among the samples. These also showed the highest relative frequencies of the material studied and were important pollen sources for bees in the study area.

High Stimulus

Honey bees, Apis mellifera L., typically reject pollen of upland cotton, Gossypium hirsutum L., as a resource. This study evaluated the potential of stimulating bees for enhanced pollen collection in overcoming this rejection. In 2002, 16 equal-sized colonies of each of two commercial stocks of bees (Italian and Russian) were placed adjacent to cotton fields at Rosedale, LA, and manipulated so that half of the colonies of each bee type had high stimulus to collect pollen and half had low stimulus. Differential stimuli were achieved by interchanging combs having relatively large amounts of brood with combs having pollen, between colonies of the two treatment groups (i.e., high stimulus colonies donated pollen and received brood, whereas low stimulus colonies had the converse). Stimulus manipulations resulted in more general pollen collection, but not cotton pollen collection, in the high stimulus group on days 1 and 6 after treatment. Foraging responses of the treatment groups equalized by 11 days after treatment. Collection of cotton pollen was minimal (≤2% of all foragers) during this period and was not affected by stimulus treatment. Italian colonies had greater total foraging activity and pollen collection effort on day 1 after treatment, but the bee types foraged similarly on days 6 and 11. There were no interactions of the effects of stimulus treatment and bee type. After the treatment effects dissipated (by day 11, 5 August 2002), collection of cotton pollen increased substantially. Approximately one-fourth of all foragers and 80% of pollen collectors carried cotton pollen pellets during a 2-wk period in midAugust. In 2004, observations of 11 colonies at a cotton planting near Fordoche, LA, showed that foragers again carried notable amounts of cotton pollen during the middle of bloom but little cotton pollen earlier or later. At the peak, a mean of 26% of pollen loads of all colonies and 50–59% of pollen in two colonies were of cotton. The reason for this unexpected willingness to gather cotton pollen is undetermined and warrants investigation because of the potential importance for cotton pollination by honey bees.

AbstractColletes hederae,the ivy bee, (Hymenoptera: Colletidae) has undergone large range expansions in Europe in recent years, including colonising Britain in 2001 with its original distribution limited to Western mainland Europe and the Channel Islands. It is thought to specialise onHedera helixL. (Apiales: Ariliaceae), common ivy. However, some research has questioned this dependence. This study quantifies the foraging ecology ofC. hederaeto determine its relationship with ivy in Sussex. We quantified the phenology of ivy bloom,C. hederaeactivity and flower visitation, and pollen collection of females through pollen analysis. We also gathered equivalent data onApis melliferaboth as a comparison and to assess alternative pollen sources. The phenology of femaleC. hederaeactivity was highly correlated with and phonologically contained within the ivy bloom period. Pollen analysis fromC. hederaeidentified ivy pollen was 98.5% of samples, significantly more than forA. mellifera(90%). Two other plant species were identified and more common inC. hederaesamples when ivy bloom was not at its peak. Surveys of ivy flowers surrounding the aggregations found thatC. hederaewere the most common insect (26%) foraging on ivy.AlthoughC. hederaecan forage on other species, ivy was found to be an important floral resource. The results also suggest the potential for competition withA. mellifera, the only other bee present in more than small numbers onH. helixflowers, as althoughA. melliferais a generalist, in autumn it mainly forages on ivy.
