Abstract

Arboviruses transmitted by arthropods are a global public health threat due to their expanding geographic range, attributed to the availability of efficient vectors. While Aedes aegypti and Ae. albopictus are well-known vectors, other Aedes species, such as Ae. japonicus, Ae. vexans, and Ae. vittatus, are becoming a concern. This article provides a comprehensive review of the global distribution, breeding habitats, and virus transmission potential of Ae. vittatus, a mosquito species known to transmit yellow fever, Zika, chikungunya, and dengue virus, as well as reports on the potential use of natural products as mosquito control agents.

This research article describes a study in which extracts from Murraya paniculata were tested for their larvicidal activity against the 4th instar larvae of Ae. vittatus. The extracts were prepared using different solvents and screened for the presence of secondary metabolites which exhibit insecticidal properties. The prepared extracts were tested at various concentrations using larvae in different stages. Methanolic extracts contained all tested secondary metabolites and exhibited the highest insecticidal activity, with a mortality rate of 100% at 250 ppm. Aqueous and Ethanolic extracts also showed significant insecticidal activity, while n-Hexane extracts demonstrated moderate activity. These findings suggest that M. paniculata leaves contain insecticidal compounds that can be utilized for mosquito control. Further research is needed to isolate and identify the active compounds responsible for the observed activity.
