Entomotoxic efficacy of fungus-synthesized nanoparticles against immature stages of stored bean pests.

ABSTRACT: Nanopesticides, particularly biosynthesized ones using organic reductants, hold great promise as a cost-effective and eco-friendly alternative to chemical pesticides. However, their efficacy on stored product pests, which can cause damage to dried grains, has not been extensively tested, especially on immature stages. Here, we biosynthesized six types of nanoparticles (NPs) using extracts from the fungus Fusarium solani: silver (AgNPs), selenium (SeNPs), silicon dioxide (SiO₂NPs), copper oxide (CuONPs), titanium dioxide (TiO₂NPs) and zinc oxide (ZnONPs) ranging in size from 8 to 33 nm. To test their efficacy on stored bean pests, they were applied to the eggs and larvae of pest beetles Callosobruchus chinensis and Callosobruchus maculatus (Coleoptera: Chrysomelidae: B
