A worldwide decline of pollinator abundance is recorded and the worldwide pollination of insect-pollinated crops has traditionally depended on a single species, the honeybee. The risks of relying on a single species are obvious. Other species have been developed for particular crops. Here we present an extension of the framework of Bosch and Kemp (2002) that deals on how to develop a bee species into a crop pollinator. We used nesting aids in different settings to address five important issues… 
Towards a sustainable management of bees of the subgenus Osmia (Megachilidae; Osmia) as fruit tree pollinators
These factors include nesting material, release methods, and control of antagonists as well as methods optimising management of developmental stages to synchronize bee activity with orchard bloom and to minimize developmental mortality.
The best wildflowers for wild bees
This work identifies wildflowers that are attractive to a greater range of wild bee species and suggests that the standard ‘pollinator’ mixes used in AES might be updated to include some of these wildflower species, and trialled as seed mixes on farmland.
Managing trap‐nesting bees as crop pollinators: Spatiotemporal effects of floral resources and antagonists
Trap nests could be a simple pollinator-supporting strategy to accompany the current expansion of mass-flowering crops, and to ensure pollination services for insect-pollinated crops.
Use of Osmia bicornis L. for Pollination of Cyclamen persicum Mill. Cultivated in Greenhouse Environment During Winter Period
Abstract In this study, the pollinating potential of the red mason bee (Osmia bicornis syn. O. rufa) in seed production of a major ornamental plant - Persian cyclamen (Cyclamen persicum), was
Effectiveness of UK agri-environment schemes in supporting cavity-nesting solitary bees
Examination of bee foraging preferences, through next generation sequencing of brood cell pollen DNA, demonstrated that the agri-environment scheme sown wildflower mixes do not support the foraging requirements of solitary bees effectively.
Almond orchards with living ground cover host more wild insect pollinators
Keeping living ground cover within commercial almond orchards could provide habitat and resources for potential wild pollinators, particularly native bees, which have the potential to provide a valuable ecosystem service to pollinator-dependent crops such as almond.
Supporting crop pollinators with floral resources: network-based phenological matching
This framework could be used to provide native bee communities with additional, well-targeted floral resources to ensure that they not only survive, but also thrive.
The underestimated taxa: the role of non-bee pollinators in temperate vegetable crops, experimental research in strawberry (Fragaria spp.) crops
The aim of this thesis is to demonstrate the diversity of non-bee insects that visit temperate vegetable crops in a comprehensive review and presents research on the non- bee floral visiting community of dayneutral strawberries in Southern-Ontario.
Seasonal shifts and complementary use of pollen sources by two bees, a lacewing and a ladybeetle species in European agricultural landscapes
The findings support incentives that promote heterogeneous agricultural landscapes including both woody and herbaceous semi‐natural habitats, ensuring phenological complementarity of floral resources for insect species that can provide pollination and pest control services to agriculture.
Impact of enhanced Osmia bicornis (Hymenoptera: Megachilidae) populations on pollination and fruit quality in commercial sweet cherry (Prunus avium L.) orchards
The impact on pollination of supplementing wild pollinators with commercially reared Osmia bicornis in commercial orchards growing the self-fertile sweet cherry variety “Stella” was investigated in each of two years, but harvested fruit following supplemented pollination were consistently larger and heavier compared to those from the wild pollinator treatment.


Developing and establishing bee species as crop pollinators: the example of Osmia spp. (Hymenoptera: Megachilidae) and fruit trees
The development of a bee species as a new crop pollinator starts with the identification of a pollination-limited crop production deficit and the selection of one or more candidate pollinator species, and culminates with the delivery of a viable system to manage and sustain the new pollinator on a commercial scale.
Crop pollination from native bees at risk from agricultural intensification
It was found that diversity was essential for sustaining the service, because of year-to-year variation in community composition, and conservation and restoration of bee habitat are potentially viable economic alternatives for reducing dependence on managed honey bees.
Orchard pollination in Capitol Reef National Park, Utah, USA. Honey bees or native bees?
It is suggested that gradual withdrawal of honey bees from Capitol Reef National Park would help conserve native bee populations without decreasing orchard crop productivity, and would serve as a demonstration of the commercial value of native pollinators.
Pollinating Efficacy of Osmia cornuta and Apis mellifera (Hymenoptera: Megachilidae, Apidae) on ‘Red Delicious’ Apple
This result indicates that 530 nesting O. cornuta females per hectare are enough to provide adequate apple pollination, and that A. mellifera pollen collectors had very high rates of stigma contact, but they were very scarce on ‘Delicious’ flowers despite the presence of abundant brood in their hives.
Searching for a Manageable Pollinator for Acerola Orchards: The Solitary Oil-Collecting Bee Centris analis (Hymenoptera: Apidae: Centridini)
This work proposes the commercial use of Centris bees as orchard pollinators for the first time, and analyzes trap-nest acceptance, brood-cell construction, and larval diet in Acerola orchards to develop protocols for rearing and management.
Osmia cornuta (Hymenoptera Megachilidae) densities required for apple pollination: a cage study
One O. cornuta pair per five trees can provide commercially acceptable fruitlet-set and thus high-quality yields on ‘Braeburn’ apple, whereas one O. maize pair per tree can ensure maximum seed- set and therefore high- quality yields on’ Braeburn.
It is concluded that floral resources act in specific and previously unexplored ways to modulate the diversity of the local geographic species pool, with specific disturbance factors, superimposed upon these patterns, mainly affecting the dominant species.
Importance of pollinators in changing landscapes for world crops
It is found that fruit, vegetable or seed production from 87 of the leading global food crops is dependent upon animal pollination, while 28 crops do not rely upon animalPollination, however, global production volumes give a contrasting perspective.
Diversification of pollination strategies for U.S. crops
The close affiliation between the honey bee industry and commercial pollination of U.S. crops is described, followed by a literature review that demonstrates why insufficient numbers of honey bees
How much does agriculture depend on pollinators? Lessons from long-term trends in crop production.
It is proposed that pollination shortage will intensify demand for agricultural land, a trend that will be more pronounced in the developing world, and increasing pressure on supply of agricultural land could significantly contribute to global environmental change.
