Insecticidal fungal metabolites fabricated chitosan nanocomposite (IM-CNC) preparation for the enhanced larvicidal activity - An effective strategy for green pesticide against economic important insect pests

Synthesis of Metarhizium anisopliae–Chitosan Nanoparticles and Their Pathogenicity against Plutella xylostella (Linnaeus)

“…This study reports the production and characterization of M. anisopliae-chitosan nanoparticles. The FTIR profiles of synthesized chitosan nanoparticles, M. anisopliae toxin-chitosan nanoparticles and M. anisopliae hyphae-chitosan nanoparticles showed the presence of O-H or N-H stretching and carbonyl stretch amide linkage, which is similar to the FTIR profile of Noumeraea rileyi-chitosan nanoparticles, explained by Namasivayam et al [14]. The changes in O-H or N-H stretching and carbonyl stretch amide linkage of nanoparticles in this study confirmed structural changes in response to the chitosan coating of metabolites or fungal conidia [44].…”

“…Nanotechnology is increasingly being used in areas of pesticide production and pest management [13,14]. Nanotechnology can be helpful in enhancing crop yield as well as developing new pest management technologies [15,16].…”

“…Polymer-based nanomaterials such as chitosan have gained much attention in various areas of agriculture. Chitosanderived nanoparticles have possible biological activities due to their biodegradable and nontoxic properties [14]. Chitosan nanoparticles are generally formulated by physical and chemical methods and are globally used for numerous applications including agriculture and drug delivery.…”

“…The effective biocontrol potential of chitosan nanoparticles against plant pathogens such as Fusarium solani associated with various economic important crops suggested the formulation and application of chitosan nanoparticles as a natural antifungal agent to enhance its antifungal activity [22]. Namasivayam et al [14] observed enhanced pesticidal activity and biocompatibility of chitosan nanocomposite prepared with the chitosan-fungal biopesticidal agent Nomuraea rileyi against Spodoptera litura. This study focuses on the synthesis, characterization and toxicity of M. anisopliae-chitosan nanoparticles, which will enhance knowledge on the development of nanoformulations of entompathogenic fungi by mixing their conidia with other nanomaterials such as chitosan.…”

Matrine Enhances the Pathogenicity of Beauveria brongniartii Against Spodoptera litura (Lepidoptera: Noctuidae)

“…Entomopathogenic fungi are promising agents in regulation populations of S. litura (Chaudhari et al, 2016; Nguyen et al, 2017; Namasivayam et al, 2018; Sahayaraj et al, 2018; Kaur et al, 2019; Yang et al, 2019). Fungi belonging to genus Beauveria (Hypocreales: Cordycipitaceae) are one of the most common insect pathogenic fungal species, which can act as an alternative to pesticides against S. litura (Borja et al, 2018; Dhar et al, 2019; Yang et al, 2019).…”
