Examining effects of ontogenic microplastic transference on Culex mosquito mortality and adult weight

Polystyrene MP beads (yellow dots) are ingested by Culex mosquito larvae and transferred to the non-feeding pupal stage during metamorphosis. When adults emerge they carry the MPs in their abdomen from the freshwater up into the terrestrial environment. The amount of plastic transferred reduces with each stage but has no impact on growth or mortality.57
