title: Cocos nucifera coir-mediated green synthesis of Pd NPs and its investigation against larvae and agricultural pest.
abstract: In recent decades, several scientists focused their process towards nanoparticles synthesis by using various sustainable approaches. Cocos nucifera (C. nucifera) was one of the versatile trees in tropical regions which also can act as a thrust quencher in all over the world. Cocos nucifera coir was one of the waste by-products in all coconut-refining industries and with the help C. nucifera coir, Palladium nanoparticles (Pd NPs) were synthesized. Green-synthesized spherical-shape Pd NPs were over layered by secondary metabolites from C. nucifera coir extract and with an average particle size of 62 ± 2 nm, which were confirmed by morphological analysis. Eco-friendly mediated Pd NPs were further subjected to several biological applications like larvicidal against Aedes aegypti (A. aegypti) and anti-feedent, ovicidal, and oviposition deterrent against agricultural pest Callasobruchus maculates (C. maculates) and compared with C. nuciferacoir methanolic extract, which results in LC50value of 288.88 ppm and LC90value of 483.06 ppm using LSD-Tukey's test against dengue vector (A. aegypti). Cocos nucifera coir methanolic extract shows significant output while compared with Pd NPs towards anti-feedent assays; ovicidal activity and oviposition deterrent were discussed here.
