Impact of Biotic and Abiotic Stressors on Managed and Feral Bees

Insects, Journal Year: 2019, Volume and Issue: 10(8), P. 233 - 233

Published: Aug. 1, 2019

Large-scale declines in bee abundance and species richness over the last decade have sounded an alarm, given crucial pollination services that bees provide. Population dips specifically been noted for both managed feral species. The simultaneous increased cultivation of bee-dependent agricultural crops has rise to additional concern. As a result, there surge scientific research investigating potential stressors impacting bees. A group environmental anthropogenic negatively isolated. Habitat destruction diminished availability floral resources nest habitats, while massive monoculture plantings limited access variety pollens nectars. rapid spread resistance buildup various parasites, pathogens, pests current control methods are implicated deteriorating health. Similarly, many pesticides widely applied on within beehives toxic global distribution honey colonies (including queens with attendant bees) bumble from crop events linked pathogen stress competition native resources. Climatic alterations disrupted synchronous emergence flower blooming reduced diverse resources, leading physiological adaptations. Interactions amongst multiple created colossal maladies hitting at one time, some cases delivering additive impacts.

In this review, recent findings regarding impact these strategies mitigating them discussed.

County-level analysis reveals a rapidly shifting landscape of insecticide hazard to honey bees (Apis mellifera) on US farmland

Scientific Reports, Journal Year: 2020, Volume and Issue: 10(1)

Abstract Each year, millions of kilograms insecticides are applied to crops in the US. While insecticide use supports food, fuel, and fiber production, it can also threaten non-target organisms, a concern underscored by mounting evidence widespread decline pollinator populations. Here, we integrate several public datasets generate county-level annual estimates total ‘bee toxic load’ (honey bee lethal doses) for US between 1997–2012, calculated separately oral contact toxicity. To explore underlying components observed changes, divide load into extent (area treated) intensity (application rate x potency). We show that while contact-based remained relatively steady, oral-based increased roughly 9-fold, with reductions application outweighed disproportionate increases potency (toxicity/kg) extent. This pattern varied markedly region, greatest increase seen Heartland (121-fold increase), likely driven neonicotinoid seed treatments corn soybean. In this “potency paradox”, farmland central has become more hazardous bees despite lower volumes applied, raising concerns about insect conservation highlighting importance integrative approaches pesticide monitoring.

Toxic Effects of Pesticides on Humans, Plants, Animals, Pollinators and Beneficial Organisms

Asian Plant Research Journal, Journal Year: 2020, Volume and Issue: unknown, P. 37 - 47

Published: Aug. 5, 2020

Pesticides are a hidden threat to humans, animals, insects, as well all ecosystems. They control pests and play an important role in crop productivity prevent vector borne-diseases but they also extremely pollute our surroundings. These toxic substances found soil, water, air, plants, food feed. Their residues enter plants animal products accumulate humans animals by the chain. endanger lives put down health, demolish beneficial organisms environment. This paper expresses piece of information that has been obtained from reviewing academic papers, books other sources. People take these chemicals agricultural products, their stored animals’ tissues or excreted different routes, adverse effects have no end. Brain, kidneys, skin, gastrointestinal, liver, lungs, spleen every organ suppressed them. cause various diseases, cancers, mutations, lead death. destroy honeybees’ colonies decrease pollinator’s populations. Additionally, birds, wildlife soil heavy application pesticides. damage human beings, pollinators, honeybees, microorganisms. Increasing pesticides decreases population organisms, impacts health. If living diminished, threatened shortage, collapsed economy, increased feed demand, therefore new crises including famine diseases prosperity.

Pollinator monitoring more than pays for itself

Journal of Applied Ecology, Journal Year: 2020, Volume and Issue: 58(1), P. 44 - 57

Abstract Resilient pollination services depend on sufficient abundance of pollinating insects over time. Currently, however, most knowledge about the status and trends pollinators is based changes in pollinator species richness distribution only. Systematic, long‐term monitoring urgently needed to provide baseline information their status, identify drivers declines inform suitable response measures. Power analysis was used determine number sites required detect a 30% change populations 10 years. We then evaluated full economic costs implementing four national schemes UK: (a) professional monitoring, (b) service (c) volunteer collected pan traps (d) focal floral observations. These were compared separate, expert‐designed research networks benefits threatened by loss. Estimated scheme ranged from £6,159/year for 75‐site flower observation £2.7 M/year an 800‐site network.

The Impact of Pesticides on Flower‐Visiting Insects: A Review with Regard to European Risk Assessment

Environmental Toxicology and Chemistry, Journal Year: 2019, Volume and Issue: 38(11), P. 2355 - 2370

Published: Aug. 13, 2019

Abstract Flower‐visiting insects (FVIs) are an ecologically diverse group of mobile, flying species that should be protected from pesticide effects according to European policy. However, there is ongoing decline FVI species, partly caused by agricultural applications. Therefore, the risk assessment framework needs improved. We synthesized peer‐reviewed literature on groups and their ecology, habitat, exposure pesticides, subsequent effects. The results show FVIs far more than previously thought. Their entire landscape, potentially contaminated with pesticides through multiple pathways. Pesticide at environmentally realistic levels can cause population‐relevant adverse This knowledge was used critically evaluate regulatory effect assessment. current amended incorporate specific ecological properties FVIs, is, traits. present data‐driven tools improve future assessments making use trait information.

Integrated pest and pollinator management – expanding the concept

Frontiers in Ecology and the Environment, Journal Year: 2021, Volume and Issue: 19(5), P. 283 - 291

Published: March 9, 2021

The objective of integrated pest and pollinator management (IPPM) is to co‐manage for control pollination goals. Departing from the well‐established concept management, we include in a hierarchical decision support system actions. We depict this as an IPPM pyramid. Priority given proactive measures at base pyramid, which are undertaken through landscape crop field mobile organisms, primarily arthropods. Farther up practices form reactive use biotic abiotic inputs should align with basal goal minimize trade‐offs, maximize co‐benefits synergies between management. contend that has potential contribute sustainable pollination, well provide broader environmental benefits.
