Abstract

Culex quinquefasciatus Say, is the principal vector of filariasis. Bisphenol A- substitute, Bisphenol S (BPS) is a xenobiotic used in plastic products, which leach out to the environment. The present studies focuses on the effect of BPS on the duration of stages of life cycle and select biochemical parameters in C. quinquefasciatus at 0.5, 1 and 2 ppm. A significant reduction in the duration of life cycle was observed in egg rafts reared in BPS. An increase in the total protein content along with a reduction in total free amino acid was observed in the 4th instar larvae. The content of uric acid showed a sharp increase. An elevation in the level of aspartate aminotransferase and alanine aminotransferase were observed. The present study revealed that xenobiotic, BPS which is now widely used as a substitute for endocrine-disruptor BPA facilitated rapid moulting in C. quinquefasciatus mosquitoes.

Conclusion

Widespread awareness on endocrine-disrupting properties of BPA has created a huge influx of its substitutes in to the market and finally to the ecosystem. The present study is an eye-opener due to the fact that BPA substitute BPS is also having similar effects on the aquatic ecosystem, especially on Culex mosquitoes in which they reduce the life cycle duration producing more number of generations within a brief time. Plastic waste management itself can act as a vector control strategy through which release of mosquito developmental agonist in the ecosystem can be minimized.
