Environmental pollution effect on honey bees and their derived products: a comprehensive analysis

Environmental Science and Pollution Research, Journal Year: 2024, Volume and Issue: unknown

Published: June 7, 2024

Abstract Several factors, including environmental degradation, air pollution, intense urbanization, excessive agriculture, and climate change, endanger the well-being of animals plants. One major issues with an increasingly negative impact is agricultural contamination pesticides antibiotics. Seed coatings neonicotinoid insecticides used as a protective layer against pests are shown to exceed permissible limits in most cases. Neonicotinoid compounds bind nicotinic acetylcholine receptors, therefore affecting honey bees’ brain. Heavy metals higher concentrations lethal for bees, residue bee products might pose threat human health. Highly effective acaricides treat Varroa destructor infestations colonies have effects on reproduction, olfaction, production. Furthermore, amitraz fluvalinate mostly found highest amounts lead decreased production reduced colony along learning ability memory. However, scientific studies that bees act reliable bio-indicator pollution. In response growing demand products, adulteration improper storage conditions gotten worse represent new risk factor. light shifting global economy, it important analyze consumer expectations adjust manufacturing accordingly. By ensuring manufacture high-quality, traceable devoid drug residues, consumers will be better protected from subsequent health problems. This review’s objectives based necessity identifying risks associated products. Graphical abstract

Acute exposure to fungicide fluazinam induces cell death in the midgut, oxidative stress and alters behavior of the stingless bee Partamona helleri (Hymenoptera: Apidae)

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 282, P. 116677 - 116677

Published: July 5, 2024

Stingless bees (Hymenoptera: Meliponini) are pollinators of both cultivated and wild crop plants in the Neotropical region. However, they susceptible to pesticide exposure during foraging activities. The fungicide fluazinam is commonly applied bean sunflower cultivation flowering period, posing a potential risk stingless bee Partamona helleri, which serves as pollinator for these crops. In this study, we investigated impact acute oral (24 h) on survival, morphology cell death signaling pathways midgut, oxidative stress behavior P. helleri worker bees. Worker were exposed 24 h (field concentrations 0.5, 1.5 2.5 mg a.i. mL

Single and Synergistic Effects of Microplastics and Difenoconazole on Oxidative Stress, Transcriptome, and Microbiome Traits in Honey Bees

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 23, 2025

Microplastics (MPs) and pesticides are identified as two environmental pollutants. In the present study, we showed evidence of toxic effects on honey bees from chronic oral exposure to food containing difenoconazole alone (Dif) in a binary mixture with polystyrene (PS)-MPs (Dif + PS). We observed disrupted gut microbial community structure after exposure, microbiota richness increased at phylum genus levels Dif PS group. Transcriptomic analysis revealed that caused 98 differentially expressed genes (DEGs), while 41 DEGs were PS-MPs seemed mitigate oxidative damage changes transcriptome profile by some extent. However, coexposure disordered composition. Our study highlights importance investigating possible additive synergic activities between stressors comprehensively understand pollutants pollinating insects.

Short Exposures to Phosphine Trigger Differential Gene Expression in Phosphine-Susceptible and -Resistant Strains of Tribolium castaneum

Genes, Journal Year: 2025, Volume and Issue: 16(3), P. 324 - 324

Published: March 10, 2025

Background/Objectives: Phosphine resistance in insects involves a complex interplay of genetic and physiological factors, which are often poorly understood. Resistance to high concentrations phosphine worldwide poses formidable challenge for stored-product pest management affects global food security. Understanding the basis red flour beetle, Tribolium castaneum, is urgent because species’ status as notorious insect stored grains their major classes insecticides. In this study, we take advantage T. castaneum model species biological studies. Methods: To tease apart mutations differential expression genes responding intoxication, set up 16 different exposure tests compare effects dose, time, sampling time on gene phosphine-susceptible -resistant adults. Results: We examined enrichment ontology terms that were differentially expressed found data further distinguished differences by strain, recovery from exposure. The gene-encoding cytochrome P450 9e2 was more phosphine-resistant compared under all treatment conditions significantly higher resistant sampled after short or long exposures. Therefore, may serve new marker can be utilized diagnostic tool detection. Conclusions: These important understand molecular changes have reduced sensitivity develop monitoring prevention strategies.

Difenoconazole Degradation by Novel Microbial Consortium TA01: Metabolic Pathway and Microbial Community Analysis

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(7), P. 3142 - 3142

Published: March 28, 2025

Difenoconazole, a broad-spectrum systemic fungicide, can effectively prevent and control plant diseases such as rice blast, leaf spot, black spot caused by Colletotrichum godetiae, Alternaria alternata, Neopestalotiopsis rosae. However, its residual accumulation in the environment may pose potential toxicity risks to non-target organisms. In this study, highly efficient DIF-degrading microbial consortium TA01 was enriched from long-term pesticide-contaminated soil laboratory-based adaptive evolution strategy. The able degrade 83.87% of 50 mg/L DIF within 3 days. addition, three intermediate metabolites were identified using HPLC-MS/MS, results indicated that degradation involve catalytic reactions hydrolysis, dehalogenation, hydroxylation. High-throughput sequencing showed Pantoea, Serratia, Ochrobactrum, Bacillus dominant members involved process. Finally, bioremediation capacity experiments inoculation with accelerate water-sediment system. findings study not only enrich resources available for but also offer new strategies situ remediation contamination.

Fungal diseases of agricultural crops cause severe economic losses to the growers. For control these diseases, azoxystrobin is one recommended fungicides. This fungicide systemic in action and expected reach floral part treated crop its residue pollen nectar, natural food sources honey bees, which could be collected fed on by thus affecting their health. The purpose this study was determine physiological chemical changes caused bee workers (Apis mellifera L). Workers at 1, 8, 21 days old were with 125, 167, 250 mg/L concentrations for seven days; survival rates, activities carboxylesterase (CarE), glutathione S-transferases (GSTs), cytochrome P450 enzyme (CYP450), catalase (CAT), superoxide dismutase (SOD) enzymes, expression levels immune (Aba, Api, Def1, Hym) nutrition genes (Ilp1, Ilp2, Vg) detected. Our findings revealed that affected workers, particularly 1- 21-day-old who responded stress increased detoxification protective might have costs. Additionally, genes, a decreased trend compared 8-day-old leading reduced resistance external stressors mortality rates. These provide important insights into adverse effects different ages emphasize potential risks colony stability individual recommends an urgent ban such harmful being used fungi agriculture, especially during plant flowering.
