Honey bee is vital for pollination and ecological services, boosting crops productivity in terms of quality quantity production colony products: wax, royal jelly, venom, honey, pollen propolis. bees are most important plant pollinators almost one third diet depends on bee's pollination, worth billions dollars. Hence the role that honey have environment their economic importance food production, health dominant significance. can be infected by various pathogens like: viruses, bacteria, fungi, or infested parasitic mites.

Diversified Farming in a Monoculture Landscape: Effects on Honey Bee Health and Wild Bee Communities

Environmental Entomology, Journal Year: 2020, Volume and Issue: 49(3), P. 753 - 764

Published: March 19, 2020

In the last century, a global transformation of Earth's surface has occurred due to human activity with extensive agriculture replacing natural ecosystems. Concomitant declines in wild and managed bees are occurring, largely lack floral resources inadequate nutrition, caused by conversion monoculture-based farming. Diversified fruit vegetable farms may provide an enhanced variety through crops weedy plants, which have potential sustain bee nutrition. We hypothesized can enhance honey (Hymenoptera: Apidae, Apis mellifera Linnaeus) colony growth nutritional state over soybean monoculture, as well support more diverse community. tracked growth, state, abundance, richness, diversity both farm types. Honey kept at diversified had increased weight preoverwintering state. Regardless location, precipitous during autumn thus colonies were not completely buffered from stressors living matrix dominated monocultures. Contrary our hypothesis, was greater soybean, specifically August, time when fields bloom. These differences driven four common species that performed soybean. Overall, these results suggest some benefits for bees; however, they do benefit communities. Thus, incorporation habitat, rather than farming, landscapes, be better choice conservation efforts.

Do Viruses From Managed Honey Bees (Hymenoptera: Apidae) Endanger Wild Bees in Native Prairies?

Environmental Entomology, Journal Year: 2020, Volume and Issue: 50(2), P. 455 - 466

Published: Dec. 15, 2020

Abstract Populations of wild and managed pollinators are declining in North America, causes include increases disease pressure decreases flowering resources. Tallgrass prairies can provide floral resources for honey bees (Hymenoptera: Apidae, Apis mellifera Linnaeus) bees. Honey kept near may compete with resources, potentially transfer viral pathogens to Measurements these potential interactions lacking, especially the context native habitat conservation. To address this, we assessed abundance richness without bee hives present, spillover several viruses bumble Bombus Latrielle). We found no indication that presence over 2 yr had a negative effect on population size taxa, though longer-term remains unknown. All levels quantified were lower than those observed Higher deformed wing virus Israeli acute paralysis griseocollis DeGeer Apidae) collected at sites hives. These data suggest tallgrass prairie could increase exposure viruses. Additional studies cross-species transmission needed inform decisions regarding cohabitation within utilized by

CSI Pollen: Diversity of Honey Bee Collected Pollen Studied by Citizen Scientists

Insects, Journal Year: 2021, Volume and Issue: 12(11), P. 987 - 987

Published: Nov. 2, 2021

A diverse supply of pollen is an important factor for honey bee health, but information about the diversity available to colonies at landscape scale largely missing. In this COLOSS study, beekeeper citizen scientists sampled and analyzed collected by colonies. As a simple measure diversity, beekeepers determined number colors found in samples that were coordinated standardized way. Altogether, 750 from 28 different regions 24 countries participated two-year study almost 18,000 samples. Pollen contained approximately six total throughout sampling period, which four abundant. We ran generalized linear mixed models test possible effects factors such as collection, i.e., whether minimum amount was or not, habitat type on To identify beekeepers' descriptions surrounding CORINE land cover classes investigated two models, both showed rare positively affected 'urban' habitats 'artificial surfaces', respectively. This science underlines importance bees suggests higher urban areas.

North American Prairie Is a Source of Pollen for Managed Honey Bees (Hymenoptera: Apidae)

Journal of Insect Science, Journal Year: 2021, Volume and Issue: 21(1)

Abstract Prairie was a dominant habitat within large portions of North America before European settlement. Conversion prairies to farmland resulted in the loss proportion native floral resources, contributing decline pollinator populations. Efforts reconstruct prairie could provide honey bees (Apis mellifera) source much-needed forage, especially regions dominated by crop production. To what extent bees, which were introduced settlers, use plants is unclear. We placed colonies with pollen traps reconstructed central Iowa determine and how much collected from plants. Honey bee more nonnative than during June July. During August September, prairies. Our results suggest that bees’ may depend upon seasonality both present landscape. This finding be useful for addressing nutritional health as this region frequently suffer dearth forage colony declines September when crops weedy cease blooming. These can significant later part growing season Midwestern United States; we discuss insight context biodiversity conservation.

Row crop fields provide mid‐summer forage for honey bees

Ecology and Evolution, Journal Year: 2022, Volume and Issue: 12(6)

Published: June 1, 2022

Abstract Honey bees provide invaluable economic and ecological services while simultaneously facing stressors that may compromise their health. For example, agricultural landscapes, such as a row crop system, are necessary for our food production, but they cause poor nutrition in from lack of available nectar pollen. Here, we investigated the foraging dynamics honey environment. We decoded, mapped, analyzed 3459 waggle dances, which communicate location where collected food, two full seasons (April–October, 2018–2019). found recruited nestmates mostly locally (<2 km) throughout season. The shortest communicated median distances (0.474 0.310 km), indicating abundant availability, occurred July both years, was when crops were bloom. determined, by plotting analyzing locations, almost half mid‐summer recruitment to crops, with 37% (2018) 50% (2019) bee dances these fields. Peanut most attractive July, followed corn cotton not soybean. Overall, fields indicated surprisingly large proportion suggesting similar landscapes also opportunities bees.

Insects, Journal Year: 2020, Volume and Issue: 11(6), P. 366 - 366

Published: June 12, 2020

To study how honey bees utilize forage resources and guide pollination management plans in crops, a multitude of methods have been developed, but most are time consuming, costly, require specialized skills. Colored pan traps for monitoring activity-density simple, efficient, cost-effective alternative; however, their usefulness studying is not well described. We examined if trap color, location within field, the presence managed colonies affected estimates bee soybean fields. Soybeans visited by pollinators do these visits seed development. Pan traps, especially those colored blue, captured more when were present. There no differences based on placement field nor with increasing distance from colonies. Throughout season, soybeans was constant tripled after ceased blooming, suggesting spikes captures may indicate periods scarcity. Activity-density did correlate population size worker at site, number conclude that can be useful assessing activity, particularly estimating colony identifying times
