The Global Contribution of Wild Insect and Honeybee Visitation to Crop Pollination Success Is Asymptotic
Background Animal-mediated pollination plays a crucial role in the reproductive success of flowering plants, and insect pollination in particular for crops. Pollination biology suggests that the effect of pollen deposition from animal visitation on pollination success is asymptotic. Initially, increased insect visitation increases pollination success in decreasing increments, eventually reaching a saturation threshold where additional visits do not further increase pollination success.
Wild Bees Setting Good Example for Pollination of Sweet Cherries
Wild bees, such as bumblebees and mason bees, have been considered important pollinators for sweet cherry. New research conducted in Belgium and Germany concludes that wild bees can do even more while having a positive effect on the pollination contribution of honeybees. In this way, wild bees have a double positive effect, namely being excellent pollinators themselves and allowing honeybees to do their job better.
Mason bees and honey bees synergistically enhance fruit set in sweet cherry orchards
Verification of mason bees as cherry flower visitors To confirm that managed mason bee populations are flower visitors of cherries, we identified the source of the pollen with which O. cornuta females provisioned their nests. To do so, we distributed 30 cardboard nesting tubes (15 of 7 mm diameter and 15 of 9 mm diameter) per site at three sites (Figure 1; sites 4, 8 and 11) before cherry bloom (end of February/beginning of March).
Effects of geographic origin and temperature on survival, development, and emergence of the managed pollinator Osmia lignaria
1. Introduction Bees serve a critical ecosystem function as pollinators and are vital for the production of pollinator-dependent crops (Klein et al., 2007; Ollerton et al., 2011; Khalifa et al., 2021). Numerous studies have noted declines in health and numbers of both managed and wild bees (e.g., LeCroy et al., 2020; Osterman et al., 2021; Zattara and Aizen, 2021) due to stressors, including loss of habitat, pests and pathogens, pesticides, and climate change (Brown and Paxton, 2009).
How organizations are planning for a carbon credit supply crunch
This article is sponsored by NCX. Demand for carbon credits is expected to increase drastically in coming decades due to the growing number of corporate net-zero commitments, with 698 of the 2,000 largest publicly traded companies in the world having made net zero commitments to be reached in or before 2050.
Managed honeybee and bumble bee colonies in the US are up as much as 85%, a 60 year high, as independent researchers challenge bee apocalypse narrative
The Western honey bee (Apis mellifera) is amongst the best-monitored insects but the state of other managed pollinators is less well known. Here, we review the status and trends of all managed pollinators based on publicly accessible databases and the published literature. We found that, on a global scale, the number of managed A. mellifera colonies has increased by 85% since 1961 [with every region showing increases except Europe, which began reversing its decline in 2010], driven mainly by Asia.
