Ontogenetic transfer of microplastics in natural populations of malaria mosquitoes in Western Siberia
The uptake, accumulation, and ontogenetic transfer of microplastics (MPs) in bloodsucking mosquitoes of the genus Anopheles, vectors of helminth and protozoa parasites in humans and animals, were studied under laboratory conditions. In the experiment, 2-μm-diameter fluorescent polystyrene spheres were counted in mosquitoes of all stages, from larvae to adults. Larvae from a natural population readily ingested MPs with food, accumulating on average 3.9 × 106 particles per larva within 3 days. The concentration of MPs decreased significantly in mosquitoes during their transition from stage to stage. The average number of detected MPs attained 110 particles per pupa and 3.0 particles per adult. MP uptake by mosquitoes did not affect their survival, whereas the rate of metamorphosis in MP-consuming mosquitoes was slightly higher. Our data confirmed that MPs can be transferred from feeding larvae to non-feeding pupae and adult flying Anopheles mosquitoes from natural populations in aquatic ecosystems.
期刊介绍：
Entomologia Experimentalis et Applicata publishes top quality original research papers in the fields of experimental biology and ecology of insects and other terrestrial arthropods, with both pure and applied scopes. Mini-reviews, technical notes and media reviews are also published. Although the scope of the journal covers the entire scientific field of entomology, it has established itself as the preferred medium for the communication of results in the areas of the physiological, ecological, and morphological inter-relations between phytophagous arthropods and their food plants, their parasitoids, predators, and pathogens. Examples of specific areas that are covered frequently are:
host-plant selection mechanisms
chemical and sensory ecology and infochemicals
parasitoid-host interactions
behavioural ecology
biosystematics
(co-)evolution
migration and dispersal
population modelling
sampling strategies
developmental and behavioural responses to photoperiod and temperature
nutrition
natural and transgenic plant resistance.
