Intracolonial trophallaxis as a molecular filter: caste-divergent transcriptomic and oxidative responses to tire wear particle exposure in Camponotus spp.
AI summary Read the abstract
I can't write an accurate summary of this paper because only the title and a repeated, non-descriptive placeholder were provided, no actual findings, methods, or results were included in the abstract text. That said, based on the title alone: this study appears to look at how carpenter ants (Camponotus) share food mouth-to-mouth with nestmates (called trophallaxis), and whether this process changes how different types of ants in the colony (like workers vs. queens) respond, at the gene and cell-damage level, to tiny particles that wear off car tires. If you'd like, please share the actual abstract or results section, and I can write you a genuinely acc

To pass on or not to pass on: The fate of orally ingested microplastic during cooperative brood care in two social Hymenoptera species
AI summary Read the abstract
Researchers tested whether microplastic particles ingested by workers of the Japanese carpenter ant (Camponotus japonicus) and the buff-tailed bumblebee (Bombus terrestris) are transferred to larvae during cooperative brood care, finding evidence that ingested microplastics can be passed from workers to brood. The study highlights a colony-level exposure pathway in ecologically important social insects that has been largely overlooked in microplastic research.
The fate of orally ingested microplastics during cooperative brood care in two social Hymenoptera species
AI summary Read the abstract
Researchers exposed carpenter ant and bumblebee colonies to polystyrene microplastics and tracked particle fate during cooperative brood care, finding that ants' infrabuccal pocket effectively filtered particles and prevented larval exposure, while bumblebee larvae ingested microplastics transferred directly from workers, suggesting colony-level MP risks differ markedly by species anatomy.
The Fate of Orally Ingested Microplastics During Cooperative Brood Care in Two Social Hymenoptera Species
AI summary Read the abstract
Scientists fed microplastic particles to ants and bumblebees to see how these tiny plastic bits move through colonies that share food and care for their young together. Ants had a built-in filter (a special mouth pocket) that trapped the plastic before it reached their larvae, but bumblebees had no such defense—meaning the plastic passed freely from adult bees to developing young. This matters because it shows some pollinator species may be far more vulnerable to microplastic pollution than others, which could affect bee populations that are crucial for pollinating the crops humans eat.
Trophic_Transfer_of_Microplastic_in_Social_Hymenoptera
AI summary Read the abstract
Microplastics can travel up through the food chain in social insects, but this study found a striking difference between ant and bumblebee colonies in how that transfer happens. When workers of both species ingested microplastic-contaminated food, bumblebee larvae received the plastic particles from their caregivers — but ant larvae did not, because worker ants have a specialized filtering organ (the infrabuccal pocket) that traps particles before they can be passed on. This finding suggests that social insect species lacking this biological filter are more vulnerable to colony-level effects of microplastic pollution.
Effects of traffic-derived airborne particulate matter on social Hymenoptera

This review examined how traffic-derived airborne particulate matter—including tire wear particles, brake dust, and microplastics—affects social Hymenoptera such as bees and ants, contributing to the broader picture of how urban pollution drives insect biodiversity decline.
