Insights into Defense Mechanisms of Engineered Nanoparticles for Management of Insect Pests and Pathogens
摘要
Nanoparticles have revolutionized agriculture due to their unique properties and paved the way for several branches including pests and disease management. Engineered Nanoparticles (ENPs) can be classified based on their ability to boost the immunity of plants, management of diseases and pests, etc. In this chapter, we discuss the mechanisms and interactions between nanoparticles, pests, and pathogens. How nanoparticles interfere with the defense of plants and immune systems fascinated scientists for a long time. Gold nanoparticles have some negative plant interactions, whereas TiO2NPs have a positive effect on plants and chitosan imparts resistance. The factors related to the host that are responsible for the interaction and development of engineered nanoparticles like host cells, biomembrane, proteins, carbohydrates, nucleic acid, and innate immunity were assessed based on their effect. dsRNA-engineered nanoparticles or vectors are novel strategies in the sustainable management of insect pests and belong to several types, like synthetic polymer-based, inorganic, peptide-based, chitosan-based, quantum dots, and liposomal nanoparticles. Despite multiple advantages, there are still concerns about the nanoparticle’s impact on the environment. But in terms of future prospects, nanoparticle-mediated control strategies can reduce pesticidal load, overcome environmental stresses, and increase the stability or effectiveness of pesticides. In this chapter, we have tried to encompass the current understanding related to engineered nanoparticles and their relationship with insect pest and pathogen management.
