Article
Full-text available
The nectar secretion of Ziziphus flowers was studied by removing and measuring the nectar every four hours, for two consecutive days, from 88 flowers of four trees (‘repeated sampling’). In another 120 flowers from the same trees, the accumulated sugar was measured at the end of the flowering stage. The mass of the nectar sugar was determined follo...

Talh trees (Acacia gerrardii Benth.) are acacias that are native to the arid and semiarid Africa and west Asia. We investigated the flowering biology, pod set and flower visitors of Talh and discussed the role of these visitors in pollen transfer. The Talh trees blossomed laterally on the nodes of one-year-old twigs. Each node produced 21 flower bu...

This study investigated the outgoing and pollen-gathering foraging activities of Apis mellifera jemenitica (AMJ) and Apis mellifera carnica (AMC) under a hot-arid environment in the presence of nectar-rich melliferous Ziziphus nummularia flora. The data revealed the differential effects of weather conditions and Z. nummularia flora on the foraging...
Article

Data Overview: An eight-year survey of Varroa destructor infestation rates of western honey bee (Apis mellifera) colonies across Austria and the spatial dimension, temporal dimension and weather factors that impact these infestation rates. Data Value: This data is valuable because it was collected and designed to build predictive models on where V...
Article
Phacelia tanacetifolia is a widely used food plant in the beekeeping and conservation of pollinators. The present work is the first report for its value as bees and insectary plants in Saudi Arabia. Insect species visiting on flowers of P. tanacetifolia were identified and clustered as pollinators, pests and natural enemies. Out of 54 recorded inse...
Article
Remote sensing (RS) and geographical information system (GIS) technology have seldom been used in apiculture. We applied these tools to map the optimum honey bee colony carrying capacity and estimate honey production during the honey flow of ‘Talh’ trees (Acacia gerrardii Benth. [Fabaceae: Mimosoideae]) in the Rawdat-Khuraim oasis, central Saudi Ar...
Article
Full-text available
Both climatic factors and bee forage characteristics affect the population size and productivity of honey bee colonies. To our knowledge, no scientific investigation has as yet considered the potential effect of nectar-rich bee forage exposed to drastic subtropical weather conditions on the performance of honey bee colonies. This study investigated...
Article
Full-text available
Nectar is used as raw material for the production of honey and as significant reward in the relationship between bees and plants during pollination. Therefore, it is important to investigate its abundance, dynamics and associated governing factors. Weather conditions are known to influence nectar production, and predicted climate changes may be res...
Article
Full-text available
Hemolymph osmolarity has great effect on honey bee health, especially in arid and semi-arid zones. It regulates water and nutrients in stressed tissues. Osmotic concentration in three races (Apis mellifera ligustica, A. m. carnica and A. m. jemenitica) of Apis mellifera was tested in central Saudi Arabia during spring and summer seasons in 2015. Ne...
Article
Full-text available
Proximate nutrient compositions of dry larvae, pupae and adults of worker Apis mellifera ligustica were determined. Chemical analyses of the samples were carried out and the amounts of 16 amino acids, 10 fatty acids and 12 metals were measured and compared with their occurrences in conventional foods of animal and plant origin. Our results show tha...
Conference Paper
Full-text available
Lacy phacelia or purple tansy, Phacelia tanacetifolia (Family: Boraginaceae), is widely used in beekeeping and pollinators’ conservation as a food source. The plant is newly introduced to Saudi Arabia and the present work may be its first evaluation as bee and insectarium plant in this region. Seeds were grown in early December of 2014 at the Agric...
Article
Full-text available
The nature of both bee-plant interactions and pollination ecology critically depends on flowering phenology and nectar yield. These two factors determine whether the plant has the potential to produce honey by honey bees. Here, we characterized flowering phenology, quantified nectar yield and calculated honey potentiality of Talh (Acacia gerrardii...

Question
We Have tried several caging techniques to introduce laying Carniolan (Apis mellifera carnica) queens to queenlees colonies of the East African lowland honey bee (Apis mellifera scutellata). Unfortunately, nothing works!!.
Should you have experience with this issue, please do guide us!
or you please do share your thoughts should you have suggestions.
Thanks
