Abstract The pollination effectiveness (floral visitation rate, percentage of flowers pollinated, and pollen deposition) of indigenous and introduced bees visiting lowbush blueberry (Vaccinium angustifolium Aiton) was studied in Nova Scotia from 1992 to 1994. Floral visitation rate alone was not a good indicator of pollination effectiveness, as not all floral visits resulted in successful pollination events. As a group, pollen-harvesting taxa pollinated >85% of flowers visited as compared with… 

Per-visit pollinator performance and regional importance of wild Bombus and Andrena (Melandrena) compared to the managed honey bee in New York apple orchards

Although the summed pollinator importance of Melandrena and Bombus was less than that of the honey bee, these, and other, wild pollinators have a role to play in filling future pollination gaps, and thus, warrant further study and conservation.

Contrasting Pollination Efficiency and Effectiveness among Flower Visitors of Malva Sylvestris, Borago Officinalis and Onobrychis Viciifolia

Combining pollen deposition per single-visit with visitation frequency is necessary to reveal true pollinator performance and to better understand flower-visitor interactions.


Biotic pollination is an important factor for ecosystem functioning and provides a substantial ecosystem service to human food security. Not all flower visitors are pollinators, however, and

A Novel Pollen Transfer Mechanism by Honey Bee Foragers on Highbush Blueberry (Ericales: Ericaceae)

Examination of honey bee hives revealed that bee behaviors unrelated to the intentional collection of nectar and pollen, such as the frequent touching of stigmas by the claws, tarsi, or legs, while foraging, grooming, and walking across flower clusters, could result in pollen transfer.

Multiple Criteria for Evaluating Pollinator Performance in Highbush Blueberry (Ericales: Ericaceae) Agroecosystems

Evaluating pollinators of North Carolina highbush blueberry, Vaccinium corymbosum L., agroecosystems using multiple criteria shows that bee groups contribute to pollination in different ways, and these differences may provide functional complementarity and stability of pollination services to agricultural systems.

Pollination Reservoirs in Lowbush Blueberry (Ericales: Ericaceae)

The effects of PRs on wild bee diversity and the composition of bumble bee pollen loads are considered, and evidence of the positive impact ofPRs on crop pollination services is provided.

Pollination ecology and floral visitor spectrum of turtlehead ( Chelone glabra L.; Plantaginaceae)

Diurnal variation in reward presentation that was a function of both floral phenology and consumer behavior was found, possibly indicating a negative effect of non-pollinating flower visitors on plant reproductive success.

Pollinator effectiveness of native and non-native flower visitors to an apparently generalist Andean shrub, Duranta mandonii (Verbenaceae)

The present study has highlighted the importance of measuring efficiency components when documenting plant–pollinator interactions, and has demonstrated that visitation rates may give little insight into the relative importance of flower visitors.

The most effective pollinator revisited: pollen dynamics in a spring-flowering herb

Although all the visitor groups can pollinate the flowers of F. meleagris, bumblebee queens indeed proved to be the most effective pollinators of the plant, when both quality and quantity components of pollination are concerned.



Effect of a honey bee (Hymenoptera : Apidae) gradient on the pollination and yield of lowbush blueberry

The object of this study was to establish the relationship between a gradient of honey bees, Apis mellifera L., and fruit production of low bush blueberry, Vaccinium angustifolium Aiton and V.

Self-incompatibility in diploid, tetraploid, and hexaploid Vaccinium corymbosum

Self-pollination resulted in great reductions in all fertility parameters and sibling pollinations produced far fewer seedlings than cross-pollinations, mainly because the number of plump seeds per berry was reduced from an average of 21 for outcrosses to 13 for sibling crosses.

Note on the Activity of Native Pollinators in Relation to the Bloom Period of Lowbush Blueberry

Results from this study are interpreted as evidence that the older blossoms were attracting fewer pollinators than fresh blossoms.

Energetics, Patterns and Timing of Seed Dispersal in Vaccinium Section Cyanococcus

Energy content and fruiting patterns were examined for eight species in the genus Vaccinium Section Cyanococcus, the blueberries, finding whole-berry energy content was higher and seed energy lower in fruit from northern populations.

The relationship between seed number and berry weight in open-pollinated highbush blueberries

Regressions of berry weights on seed number in individual fruits of the blue berry have been reported only by Aalders and Hall (1) for Vaccinium angustifolium Ait. They obtained two highly
