Entomofaunal survey and larvicidal activity of greener silver nanoparticles: A perspective for novel eco-friendly mosquito control.

The entomofaunal survey and its toxicity of (Asteraceae) leaf aqueous extract-mediated (-LAE) silver nanoparticles (AgNPs) were assessed against selected human vector mosquitoes (HVMs). A total of 1800 individuals of 29 species belongs to 7 genera were identified. Month-wise and Genus-wise abundance of HVMs larval diversity were calculated and one-way ANOVA statistically analyzed the average physico-chemical characteristics. The relationship between physicochemical characteristics and HVMs larvae in KWS was interpreted. The total larval density and container index were 23530.18 and 1961.85 examined against 10 different containers. Various spectroscopic and microscopic investigation characterized -AgNPs. The AgNPs tested against HVMs larvae, the predominant LC/LC values of 18.17/39.56, 23.45/42.49 and 21.82/40.43 μg/mL were observed on and respectively. The findings of this investigation, improperly maintained drainages, containers and unused things in study sites, are engaged to HVMs development. This will be essential for designing and implementing HVMs control. The larval toxic potentiality of AgNPs had a prompt, inexpensive and compelling synthesis of multi-disperse action against HVMs.
