Peels of Citrus fruits (Citrus limon, Citrus hystrix, and Citrus sinensis): A potent control agent against on dengue and chikungunya vector, Asian tiger mosquito Aedes albopictus L

This study assessed the larval toxicity of peel extracts from Citrus fruits against the fourth instar larvae of the Asian tiger mosquito, Aedes albopictus, under laboratory conditions. The citrus peels were shade-dried at room temperature and coarsely powdered. Citrus limon, Citrus hystrix, and Citrus sinensis exhibit differing levels of larvicidal efficacy against various instars of A. albopictus larvae. The LC50 values for CLPE, CHPE, and CSPE against fourth instar larvae were 1.247 mg/mL, 1.235 mg/mL and 1.567 mg/mL, while the LC90 values were 2.807 mg/mL, 2.817 mg/mL and 3.291 mg/mL, respectively. The CLPE exhibits the highest larvicidal activity, followed by CHPE and CSPE. The current study demonstrates that the larvicidal potential of biowaste materials can be utilised as eco-friendly biopesticides. This approach may serve as an effective larvicidal agent and a low-cost vector control strategy, offering a viable solution to the ongoing dengue disease burden.
