Pesticides as a cause of honeybee (Apis mellifera) mortality and their persistence in honey

Biosystems Diversity, Journal Year: 2025, Volume and Issue: 33(1), P. e2501 - e2501

Published: Jan. 11, 2025

Recently, there has been a widespread decline in honeybee (Apis mellifera) colonies globally, disrupting ecological balance and reducing the pollination capacity of many entomophilous plants. One primary causes bee family deaths is increasing use pesticides, particularly insecticides, agricultural practice. This study aimed to identify mortality various regions Ukraine during 2021–2022 determine breakdown potential different pesticide groups honey. Pesticide residues biological samples were analyzed using liquid chromatography-mass spectrometry (UPLC-MS/MS) gas (GC-MS/MS). In bodies dead bees, pesticides from chemical groups, as well their mixtures, detected. most cases, cause poisoning was mixtures pyrethroids neonicotinoids: thiamethoxam, clothianidin, lambda-cyhalothrin; imidacloprid, lambda-cyhalothrin, thiamethoxam; clothianidin lambda-cyhalothrin. The found honey neonicotinoids (58.8%), triazoles (29.6%), strobilurins (6.5%), benzimidazoles (5.1%). Most levels did not exceed maximum allowable detected included thiacloprid, acetamiprid, thiamethoxam. tebuconazole, cyproconazole, flutriafol, epoxiconazole; picoxystrobin, pyraclostrobin, azoxystrobin; carbendazim thiophanate-methyl. Residues neonicotinoids, triazoles, benzimidazoles, undergo degradation over 12 months storage at 4 °C. Storing 20 °C after increased thiacloprid by 21.2%, acetamiprid 20.7%, flutriafol 36.3%. Between 9th 12th °C, picoxystrobin concentration decreased 24.5–38.0%, 80.0% complete thiophanate-methyl reached 28.0% 6th month, 46.0% 55.4% month. persistence poses significant risk toxic effects on families human health.

Beyond the urgency: pesticide Emergency Authorisations' exposure, toxicity, and risk for humans, bees, and the environment

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 947, P. 174217 - 174217

The global challenge to increase agricultural production goes along with the need of decreasing pesticide risks. European Union (EU) therefore evaluates and controls risks posed by pesticides regulating their authorisation through science-based Risk Assessment process. Member States can however act in derogation this process grant Emergency Authorisation (EA) that are currently non-authorised. To protect health humans environment, Authorisations only permitted exceptional circumstances emergency: use should be limited (i.e., cannot exceed 120 days one growing season) concurrent research on alternative strategies must enforced.

Harnessing Electrostatic Forces: A Review of Bees as Bioindicators for Particulate Matter Detection

Insects, Journal Year: 2025, Volume and Issue: 16(4), P. 373 - 373

Published: April 1, 2025

Bees (Hymenoptera, Anthophila) are widely recognized for their essential ecological roles, including pollination and biodiversity maintenance. Recently, ability to collect environmental particulate matter through electrostatic forces has been explored biomonitoring purposes. This review integrates knowledge on pollen adhesion with emerging insights into bees, emphasizing potential as bioindicators. The mechanisms of adhesion, influenced by factors such the physicochemical properties bee morphology, discussed in detail. Additionally, study evaluates efficiency pollutants, heavy metals, microplastics, nanoplastics, pathogens, pesticides, radionuclides, volatile organic compounds. multidisciplinary approach underscores role bees advancing monitoring methodologies offers innovative tools assessing ecosystem health while addressing drivers decline.

Food as Medicine: A Review of Plant Secondary Metabolites from Pollen, Nectar, and Resin with Health Benefits for Bees

Insects, Journal Year: 2025, Volume and Issue: 16(4), P. 414 - 414

Published: April 15, 2025

Bees rely on pollen and nectar for nutrition, but floral products provide more than just macronutrients; many also contain an array of plant secondary metabolites (PSMs). These compounds are generally thought to serve primarily defensive purposes appear promote longevity immune function, protect against disease agents, detoxify toxicants. This review presents a comprehensive overview PSMs, as well some fatty acids, with documented health benefits eusocial bees at ecologically relevant exposure levels the species whose and/or resin known them. We find medicinal be widespread unevenly distributed across phylogeny, few families containing majority produce PSMs benefits. discuss current state knowledge identify gaps in our understanding. The existing literature metabolites, particularly is spread multiple fields; hope that this will bring these fields closer together encourage further investigation role promoting bee ecological contexts.

Consumption of pollen contaminated with field-realistic concentrations of fungicide causes sublethal effects in Bombus impatiens (Hymenoptera: Apidae) microcolonies

Environmental Entomology, Journal Year: 2024, Volume and Issue: 53(4), P. 706 - 715

Published: May 27, 2024

Bumble bees are declining across the globe. The causes of this decline have been attributed to a variety stressors, including pesticides. Fungicides type pesticide that has understudied in context bumble bee health. As result, fungicides often applied flowering plants without consideration pollinator exposure. Recent work demonstrates sublethal effects bees, but little is known about how much fungicide it takes cause these effects. To address gap literature, we fed microcolonies common eastern (Bombus impatiens CressonHymenoptera: ApidaeHymenoptera: Apidae) pollen contaminated with range concentrations. We chose concentrations based on and nectar were reported literature. Results revealed later-stage pupae newly emerged males potentially sensitive exposure, showing smaller size reduced fat reserves at intermediate levels contamination. Compared control, intermediated fungicide-contaminated led increased pupal mortality delayed male emergence. Contrary expectations, higher did not exhibit linear relationship negative impacts, suggesting nuanced Because body emergence timing important aspects reproductive behavior, results implications for mating success, disrupting colony development.

The steady conditions of temperature, humidity and air flux within beehives make them a valuable location for conducting environmental monitoring pollutants such as PAHs. In this context, the selection an appropriate apicultural matrix plays key role in these studies, it maximizes information that will be obtained analyses while minimizing inaccurate results. present study, three matrices (honey bees, pollen propolis) two passive samplers (APIStrips silicone wristbands) are compared terms number total load PAHs detected them. Samplings took place 11 apiaries scattered Austria, Denmark, Greece, with performed by GC-MS/MS. Up to 14 different were identified wristbands pollen, whereas remaining contained maximum five contaminants. Naphthalene, 1-methylnaphthalene, 2-methylnaphthalene, pyrene found most prevalent substances environment. Recovery studies also performed; suggested chemical structure APIStrips is likely produce very strong interactions PAHs, thus hindering adequate desorption from their surface. Overall, placed inside proved suitable PAH through honey bee colonies.
