The worldwide decline of pollinators may negatively affect the fruit set of wild and cultivated plants. [] Key Result In a comparison of 24 agroforestry systems in Indonesia, the fruit set of coffee could be predicted by the number of flower–visiting bee species, and it ranged from ca. 60% (three species) to 90% (20 species). Diversity, not abundance, explained variation in fruit set, so the collective role of a species–rich bee community was important for pollination success.

Figures and Tables from this paper

Pollination by wild bees yields larger strawberries than pollination by honey bees

It is shown that honey bee pollination results in lower yields than wild bees pollination in a strawberry crop, and management efforts aimed at the maintenance or enhancement of wild pollinator populations may be a cost-effective way to increase both crop yield and biodiversity on strawberry farms.

Pollination of Coffea canephora in relation to local and regional agroforestry management

A species-rich and abundant bee assemblage will facilitate high pollination success in lowland coffee and increase fruit set and coffee yield through simple management measures and by increasing the availability of nesting sites for solitary bees.

Tropical fruit production depends on wild insect communities: bees and lychees in Thailand

It is concluded that larger-bodied bees are most likely to travel sufficiently far to import genetically diverse pollen, in this landscape-scale mosaic where non-orchard habitats were sufficient to sustain wild pollinators.

The role of bee diversity in pollination and fruit set of yellow passion fruit (Passiflora edulis forma flavicarpa, Passifloraceae) crop in Central Brazil

The results indicated that, although native pollinators still maintain economically viable natural fruit set in the region, pollination can be sustained and even enhanced by promoting conservation and management of bee diversity.

Dominance of the semi-wild honeybee as coffee pollinator across a gradient of shade-tree structure in Ethiopia

The honeybee is clearly the dominant pollinator of coffee in Ethiopia along the whole shade-tree structure gradient, and its high abundance could be a consequence of the provision of traditional bee hives in the landscape, which are colonized by wild swarming honeybees.

Functional group diversity of bee pollinators increases crop yield

This study related differences in three functional traits of pollinating bees to the seed set of the obligate cross-pollinated pumpkin Cucurbita moschata Duch, leading to enhanced crop yield without any managed honeybees.

Edible Fruit Plant Species in the Amazon Forest Rely Mostly on Bees and Beetles as Pollinators

This study built a list of edible plant species, determined the pollination syndrome of each species, and performed a review on the scientific literature searching for their pollinator/visitors to indicate the main pollinators of edible plants of the Amazon forest.



Bee pollination and fruit set of Coffea arabica and C. canephora (Rubiaceae).

Experimental evidence that cross pollination by bees causes a significant increase in fruit set of not only the self-sterile, but also theSelf-fertile coffee species is provided and the practical implication is that coffee yield may be improved by managing fields for increased flower visitation by bees.

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.

Effects of habitat isolation on pollinator communities and seed set

It is concluded that habitat connectivity is essential to maintain not only abundant and diverse bee communities, but also plant-pollinator interactions in economically important crops and endangered wild plants.

Depressed pollination in habitat fragments causes low fruit set

It is confirmed that habitat fragmentation can lead to decline in pollination and subsequent fruit set in wild plant populations and disrupted pollination interactions of the kind documented in this study may offer a substantial challenge to the conservation of biodiversity in fragmented landscapes.

Microclimatic changes and the indirect loss of ant diversity in a tropical agroecosystem

The hypothesis that the high-light environment and lack of leaf litter cover in the unshaded system are the determinants of the differences in ground-foraging ant diversity is tested and the possibility that the physical factor changes the nature of competitive interactions between the most abundant species is discussed.

The pollination ecology of buzz-pollinated Rhexia virginica (Melastomataceae).

Experimental manipulations provided little support for the hypothesis that the yellow color of melastome anthers mimics abundant pollen, thereby deceiving pollinators to visit regardless of whether most pollen has been removed, but studies of bumble bee foraging behavior and correlates of seed set provided indirect support for this hypothesis.

Effects of Land‐Use Intensity in Tropical Agroforestry Systems on Coffee Flower‐Visiting and Trap‐Nesting Bees and Wasps

The results support the idea that many nonpest and beneficial insect species may even profit from agricultural land use, and contrast with the common expectation that intensively used agroforestry systems are characterized only by loss of species.

Tropical agriculture: The value of bees to the coffee harvest

It is shown here that naturalized, non-native honeybees can augment pollination and boost crop yields by over 50% and indicate that coffee plants would benefit from being grown in habitats that are suitable for sustaining valuable pollinators.

Resource overlap and possible competition between honey bees and wild bees in central Europe

Interspecific competition by honey bees for food resources was not shown to be a significant factor determining abundance and species richness of wild bees.

The potential consequences of pollinator declines on the conservation of biodiversity and stability of food crop yields

The work group encourages increased education and training to ensure that both the lay public and resource managers understand that pollination is one of the most important ecological services provided to agriculture through the responsible management and protection of wildland habitats and their populations of pollen-vectoring animals and nectar-producing plants.
