Silver nanoparticles seem to be an excellent alternative option to control insect’s pests due to their
unique characteristics. In addition, the plant mediated synthesized silver nanoparticles have important
applications in the field of biology, agriculture and environmental due to their safety. The present work
aims to study the activity of pure and green-synthesized silver nanoparticles (Ag NP’s) against Tribolium
castaneum and Callosobruchus maculatus. The biosynthesized Ag NP’s by N. olrander were
characterized by UV-visible spectra, X-ray Diffraction (XRD), Energy dispersive spectroscopy (EDS) and
Scanning electron microscope (SEM). Larvae of T.castaneum and C. maculates were exposed to different
concentrations of pure and green-synthesized silver nanoparticles and Nerium oleander leaf extract (500,
1000, 1500 and 2000 ppm). Although the Larvicidal effect of pure silver nanoparticles against larvae of
T. castaneum (mainly first larval instar with LC50 value 2.019) and C. maculates (with LC50 value 3.366)
, the green-synthesized silver nanoparticles have more larvicidal effect. while Nerium extract have a less
effect on all larval instars of T.castaneum (LC50 value against first instar 3.853) and larvae of C.
maculates (LC50 value 4.332), The green-synthesized silver nanoparticles have more Larvicidal effect
than pure silver nanoparticles and N. oleander leaf extract.
