Abstract
Mosquito-borne diseases
pose a substantial global health threat, necessitating effective vector control
strategies. This study explores the potential of fungal metabolites as
alternative larvicidal agents against Aedes aegypti larvae, a major
vector for diseases such as dengue and filariasis. Soil samples from Nandi
Hills, Bengaluru District, Karnataka, India, yielded five distinct fungal
species, including Penicillium sp., A. niger, A. flavus, Rhizopus
sp., and Mucor sp. The isolated fungi were subjected to various
analyses, including morphological identification, confirming their abundance
and diversity. Mycelial extracts from A. flavus exhibited notable larvicidal
bioefficacy against 4th instar A. aegypti larvae, with
mortality observed after 24 hours. These findings align with previous studies
highlighting the mosquito larvicidal properties of fungal extracts, emphasizing
their promise as environmentally friendly alternatives to chemical
insecticides. The study underscores the potential application of fungal
metabolites in filariasis and dengue control suggests a novel and effective
approach to address vector-borne diseases.
