Scientific research on the impact of microplastics (MPs) in terrestrial systems is still emerging, but it has confirmed adverse health effects organisms exposed to plastics. Although recent studies have shown toxicological individual MPs polymers honey bees, different polymer combinations cognitive and behavioural performance remain unknown. To fill this knowledge gap, we investigated oral exposure spherical brain accumulation bee Apis mellifera. We evaluated acute toxicity, after a two-day exposure, polystyrene (PS - 4.8-5.8 μm) plexiglass (Poly(methyl methacrylate), or PMMA 1-40 MPs, combination two (MIX), at environmentally relevant one higher concentration (0.5, 5 50 mg L

Unravelling the microplastic menace: Different polymers additively increase bee vulnerability

Environmental Pollution, Journal Year: 2024, Volume and Issue: 352, P. 124087 - 124087

Published: May 2, 2024

Microplastics (MPs) are growing and ubiquitous environmental pollutants represent one of the greatest contemporary challenges caused by human activities. Current research has predominantly examined singular toxicological effects individual polymers, neglecting prevailing reality organisms confronted with complex contaminant mixtures potential synergistic effects. To fill this gap, we investigated lethal sublethal two common MPs, polystyrene (PS - 4.8-5.8 μm) poly(methyl methacrylate) (PMMA 1-40 μm), their combination (MIX), on pollinating insect Apis mellifera. For each treatment, evaluated oral toxicity ecologically relevant higher concentration (0.5, 5 50 mg/L) analysed immune system worker survival. As activation can alter cuticular hydrocarbon profile honey bees, used gas chromatography-mass spectrometry (GC-MS) to investigate whether MPs lead changes in chemical foragers behavioural assay test such affect patterns social recognition, undermining overall colony integrity. The results indicate an additive negative effect PS PMMA bee survival response, even at concentrations. Furthermore, alterations cuticle profiles were observed both highest intermediate concentrations, being mainly responsible. Both exposure resulted a reduction abundance several compounds. Hive entry guards did not show increased inspection or aggressive behaviour towards exposed foragers, allowing them enter without treated differently from uncontaminated foragers. These findings raise concerns only for health but also entire colony, which could be risk if contaminated nestmates undetected, spread throughout hive.

Impact of Polystyrene Micro- and Nanoplastics on the Biological Traits of the Japanese Carpenter Ant, Camponotus japonicus Mayr (Hymenoptera: Formicidae)

Insects, Journal Year: 2025, Volume and Issue: 16(3), P. 292 - 292

Published: March 11, 2025

Insects, being among the most diverse and abundant organisms in terrestrial ecosystems, are inevitably exposed to ubiquitous micro- nanoplastic contaminants. Although studies on impact of these contaminants insects gradually emerging, they remain limited scope. In this study, we investigated biological traits (including foraging behavior, food assumption, digging ability, body weight survival) Japanese carpenter ant, Camponotus japonicus, response exposure polystyrene (PS-M/NP) solutions containing three particle sizes (0.05, 1 50 μm) four concentrations (0.1, 1, 10 mg/mL). The results showed that worker ants exhibited significant preference consumption for non-contaminated multiple-choice experiments, indicating C. japonicus can differentiate avoid feeding PS-M/NP-contaminated solutions. Meanwhile, PS-M/NPs significantly reduced ability no-choice with smallest size (0.05 highest concentration (50 mg/mL) resulting longest pre-foraging period, lowest percentage licking amount consumption. addition, sand removed by ants, survival a dramatic decline decrease size, increase prolonged time study confirm have an adverse effect time-dependent manner, small high longer key factors decreasing behavior insect.

Abstract Microplastics (MPs), as an environmental contaminant, pose a significant risk to both animal and human health through the food water supply chains. Honey, widely recognised safe health‐oriented product, may become compromised if its production process involves non‐biodegradable MPs. This study was conducted systematic review, using comprehensive searches of PubMed, Scopus ScienceDirect investigate effects MP on honey bee health, potential route main species composition contamination in honey. review highlights impacts MPs including mortality, sucrose response, habituation, olfactory learning, memory recall, colony performance, body size growth, gut microbiota viral infection. From mechanistic perspective, can disrupt equilibrium microbiota, adversely impact function immune system, undermine neural signalling pathways that are critical for learning processes bees.

Revealing antagonistic interactions in the adverse effects of polystyrene and poly(methyl methacrylate) microplastics in bumblebees

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2043)

Published: March 1, 2025

Microplastics pose a significant ecological threat, yet their actual impact on terrestrial ecosystems and organisms remains poorly understood. This study investigates the effects of two common microplastics, poly(methyl methacrylate) (PMMA) polystyrene (PS), pollinator Bombus terrestris , exploring combined sublethal at three different concentrations (0.5, 5 50 mg l –1 ). PMMA PS single exposure reduced bee survival in concentration-dependent manner, whereas (MIX) had no effect. sucrose responsiveness, effect MIX enhanced it. Learning memory tests showed impaired mid-term early long-term bees exposed to PS, with effects. Interestingly, retention. Our findings emphasize differential individual microplastics bumblebee behaviour, suggesting potential risks survival, cognitive function possibly overall colony health, but also unexpected antagonistic interactions between these pollutants.
