A mini review on exposure of microplastic to Drosophila melanogaster causing sex-specific, transgenerational, locomotory, physiological and developmental effect
Summary
This mini-review synthesized studies on how polystyrene and PET microplastics affect Drosophila melanogaster across multiple biological levels including sex-specific responses, physiology, behavior, development, and transgenerational effects. Male Drosophila showed greater sensitivity to microplastics with higher mortality, and effects were both concentration- and size-dependent.
This comprehensive study focused on the diverse impacts of microplastics, specifically polystyrene and polyethylene terephthalate (PET) particles, on the model organism Drosophila melanogaster. The subsequent studies explore the effects of microplastics on Drosophila at different levels: sex-specific, physiological, behavioral, developmental, and transgenerational. Notably, the studies reveal sex-specific responses, concentration-dependent toxic effects, and size-dependent impacts of microplastics. Male Drosophila are more sensitive to microplastics, experiencing higher mortality rates and physiological alterations. The studies extend beyond immediate effects, investigating transgenerational impacts on fertility, sex ratio, and life cycles. Further the toxicological profile of PET microplastics, reveal adverse effects on climbing, jumping, crawling activities, as well as emergence rates, survival, and reproductive behaviors of the insect. These discoveries highlight the complexity of microplastic effects. The concentration-dependent and sex-specific responses highlight potential ecological risks and call for further research to understand the broader implications of microplastic exposure on both organisms and ecosystems.

Transgenerational effects on development following microplastic exposure in Drosophila melanogaster
Researchers fed Drosophila melanogaster flies plastic-supplemented food and found that while treated flies showed changes in fertility and sex ratio, their unexposed offspring had shorter larval development and reduced adult size, demonstrating transgenerational developmental effects from parental microplastic exposure.
Sex Specific Effects of PET-MPs On Drosophila Lifespan
This study examined whether sex affected how fruit flies (Drosophila) responded to PET microplastic exposure, finding that females lived longer than males when exposed to the same concentrations. Microplastics shortened lifespan in exposed flies compared to controls, and the sex-specific differences suggest hormonal or metabolic factors influence how organisms respond to plastic exposure. These findings are relevant to understanding whether microplastic health risks differ between male and female humans.
Sex-specific toxicity of PMMA Microplastics: Behavioral and metabolic dysregulation in adult Drosophila melanogaster
Drosophila melanogaster flies exposed to PMMA microplastics for 20 days showed sex-specific responses — males had enhanced motor activity while females showed metabolic disruption and shortened lifespan — highlighting the importance of considering sex differences in microplastic toxicity studies.
Intake of polyamide microplastics affects the behavior and metabolism of Drosophila
Researchers found that exposure to polyamide microplastics altered feeding behaviour, reduced triglyceride and protein levels, and disrupted metabolism in Drosophila, with effects differing between sexes and increasing in severity at higher microplastic concentrations.
Chronic exposure to polytetrafluoroethylene microplastics caused sex-specific effects in the model insect, Drosophila melanogaster (Diptera: Drosophilidae)
Researchers exposed fruit flies to polytetrafluoroethylene (PTFE) microplastics over 20 days and observed different effects depending on sex. Males showed more significant changes in energy metabolism and movement, while females experienced greater impacts on reproductive output. The study suggests that microplastic exposure can cause sex-specific biological effects even in small model organisms.
