Honeybee is a beneficial insect for human beings. However, their valuable products and colonies became decline from time to time. For instance, in the USA alone it declined from 60% to 26% from 1947 to 2008. However, the demand increased since it is important for a wide variety of uses. This review paper is, therefore, aimed to explore the major constraints of honeybee productions that were sourced from both abiotic and biotic factors and their management. Most of the constraints were extreme temperatures, relative humidity, drought, deforestation, poor apicultural practices, unsafe pesticide utilization, and pests. The constraints managed by different methods. For instance, foulbrood disease managed by destructing the infected comb, avoiding spore contaminations, drying the combs, ventilating, sanitation, and feed honeybees with sugar-syrup. The Varroa destructor is also managed by removing the infested combs, splitting colony, ventilating, and applying organic acids (e.g., lactic, oxalic, and formic like Mite-Away Quick Strips ®), ethereal oils, synthetic pyrethroids, fluvalinate, flumethrin, and predatory mites. The tetracycline antibiotics, chemotherapeutics, and sodium sulfathiazole used for antagonizing the honeybee pathogens while feeding the antibiotic fumagillin with 25 mg/1Litre sugar-syrup manages nosema.

“…3a), suggesting that pollinators that feed on nitrophobous plants were more affected than those with different feeding preferences. Insects have faster life cycles than most plants, and changes in density (WallisDeVries and van Swaay 2017) or visitation patterns (Ramos et al 2018) in response to changes in nitrogen can be quickly detected. 4b, e).…”

“…Impacts on plant community are well-recognized, including losses in species diversity (Stevens et al 2004, Bobbink et al 2010, and these may propagate to primary consumers (Stevens et al 2018). While there has been recent research into effects on herbivores (Nijssen et al 2017, Pöyry et al 2017, WallisDeVries and van Swaay 2017, the potential effects of soil eutrophication on those feeding on pollen and nectar (potential pollinators) are largely unexplored (Stevens et al 2018, but see Betzholtz et al 2013, Tamburini et al 2017, Ramos et al 2018. Such potential bottom-up effects could be mediated by reduction in nectar or pollen availability or quality (Petanidou et al 1999, Vanderplanck et al 2017.…”

Soil eutrophication shaped the composition of pollinator assemblages during the past century

Atmospheric nitrogen deposition and other sources of environmental eutrophication have increased substantially over the past century worldwide, notwithstanding the recent declining trends in Europe. Despite the recognized susceptibility of plants to eutrophication, few studies evaluated how impacts propagate to consumers, such as pollinators. Here we aim to test if soil eutrophication contributes to the temporal dynamics of pollinators and their larval resources.We used a temporally and spatially explicit historical dataset with information on species occurrences to test if soil eutrophication, and more specifically nitrogen deposition, contributes to the patterns of change of plant and pollinator richness in the Netherlands over an 80 yr period. We focus on bees and butterflies, two groups for which we have good knowledge of larval resources that allowed us to define groups of species with different nitrogen related diet preferences. For each group we estimated richness changes between different 20-yr periods at local, regional and national scale, using analytical methods developed for analyzing richness changes based on collection data.Our findings suggest that the impacts of soil eutrophication on plant communities propagate to higher trophic levels, but with a time-lag. Pollinators with nitrogenrelated diet preferences were particularly affected, in turn potentially impairing the performance of pollinator-dependent plants. Pollinator declines continued even after their focal plants started to recover. In addition, our results suggest that current levels Research 210 of nitrogen deposition still have a negative impact on most groups here analyzed, constraining richness recoveries and accentuating declines.Our results indicate that the global increase in nitrogen availability plays an important role in the ongoing pollinator decline. Consequently, species tolerances to soil nitrogen levels should be considered across all trophic levels in management plans that aim to halt biodiversity loss and enhance ecosystems services worldwide.

“…(2%), beeflies (2%), carpenter bees (3%), hoverflies (6%) and miscellaneous Lepidoptera (13%), all of which could play a role in pollination. Other work on pollination in common beans has indicated that short-tongued bees rob heavily, whereas long-tongued species are effective pollinators ( Kingha et al, 2012 ; Ramos et al, 2018 ). Although apparent evidence of robbery as indicated by holes chewed into corollas is not necessarily indicative of a major impact on fertilization, robbery events are typically much less frequent than pollinating visits ( Barlow et al, 2017 ).…”

Background Many crops are dependent on pollination by insects. Habitat management in agricultural landscapes can support pollinator services and even augment crop production. Common bean (Phaseolus vulgaris L.) is an important legume for the livelihoods of smallholder farmers in many low-income countries, particularly so in East Africa. While this crop is autogamous, it is frequently visited by pollinating insects that could improve yields. However, the value of pollination services to common beans (Kariasii) yield is not known. Methods We carried out pollinator-exclusion experiments to determine the contribution of insect pollinators to bean yields. We also carried out a fluorescent-dye experiment to evaluate the role of field margins as refuge for flower-visitors. Results Significantly higher yields, based on pods per plant and seeds per pod, were recorded from open-pollinated and hand-pollinated flowers compared to plants from which pollinators had been excluded indicating that flower visitors contribute significantly to bean yields. Similarly, open and hand-pollinated plants recorded the highest mean seed weight. Extrapolation of yield data to field scale indicated a potential increase per hectare from 681 kg in self-pollinated beans to 1,478 kg in open-pollinated beans indicating that flower visitors contributed significantly to crop yield of beans. Our marking study indicated that flower-visiting insects including bees, flies and lepidopterans moved from the field margin flowers into the bean crop. Overall, these results show that insect pollinators are important for optimising bean yields and an important food security consideration on smallholder farms. Field margin vegetation also provides habitat for flower-visiting insects that pollinate beans. Hence, non-crop habitats merit further research focusing on establishing which field margin species are most important and their capacity to support other ecosystem services such as natural pest regulation or even pests.
