Microplastics (MPs) and nanoplastics (NPs) are pervasive environmental pollutants that commonly ingested by organisms at different trophic levels. While the effects of MPs on aquatic have been extensively studied, impacts MP ingestion host fitness terrestrial organisms, mainly insects, relatively unexplored. This study investigates NP survivorship reproduction 2 medically important mosquito species, Aedes aegypti Linnaeus (Diptera: Culicidae) albopictus Skuse Culicidae). Larval pupal Ae. were not significantly affected particle size or concentration, but there was a reduction associated with 0.03 µm NPs. In addition, little observed impact 1.0 adult survivorship, fecundity, longevity. To further investigate fitness, we also examined varying shape, size, plastic polymer type immature survivorship. The data suggest shape did These findings highlight understanding microplastic mosquitoes may be complicated composition, amount ingested.
