“…Other oxide NPs were also brought to attention. In a work to evaluate the use of nano-CeO 2 on the biological and nutritional characteristics of Spodoptera frugiperda (an arthropod pest widely distributed in agricultural regions), results confirmed toxicity of nano-CeO 2 for S. frugiperda under field conditions [ 129 ]. Additionally, nano-silica was also found effectively replacing chemical insecticides to protect stored products [ 130 ].…”

New advances in nanotechnology are driving a wave of technology revolution impacting a broad range of areas in agricultural production. The current work reviews nanopesticides, nano-fabricated fertilizers, and nano activity-based growth promoters reported in the last several years, focusing on mechanisms revealed for preparation and functioning. It appears to us that with many fundamental concepts have been demonstrated over last two decades, new advances in this area continue to expand mainly in three directions, i.e., efficiency improvement, material sustainability and environment-specific stimulation functionalities. It is also evident that environmental and health concerns associated with nano agrochemicals are the primary motivation and focus for most recent work. Challenges and perspectives for future development of nano agrochemicals are also discussed.

“…Furthermore, this pest is capable of infecting cultivated grasses, most notably maize and sorghum ( Montezano et al., 2018 ; Liu et al., 2020 ; Tambo et al., 2020 ). S. frugiperda is one of the most serious noctuidae pests of maize in Thailand, China, India, and North and South America ( Tambo et al., 2020 ; Castro et al., 2021 ; Pittarate et al., 2021 ), owing to its ability to form large populations, the high larval voracity, and high rate of adult dispersal. Recent research reports have shown that S. frugiperda is an invasive pest in many countries in Africa and Asia ( Fan et al., 2020 ; Firake and Behere, 2020 ; Jing et al., 2020 ; Lee et al., 2020 ).…”

Background‘The fall armyworm, Spodoptera frugiperda’, represents a significant threat to maize production, a major staple crop in Asian countries.MethodsIn pursuit of more effective control of this insect pest, our study assessed the physiological and biochemical effects of the entomopathogenic fungus Metarhizium anisopliae against the larvae of S. frugiperda.ResultsResults revealed that, following nine days of treatment, a high concentration of conidia (1.5x107 conidia/mL-1) was toxic to all stages of larvae (second to fifth instar), resulting in 97% mortality of the second instar, 89% mortality of the third instar, 77% mortality of the fourth instar, and 72% mortality of fifth instar. All larval instars were found to have dose-dependent mortality effects. Treated S. frugiperda larvae further displayed significant physiological, morphological, and behavioral changes. Here, treated larvae displayed significantly lower levels of acetylcholinesterase, α-carboxylesterase, and β-carboxylesterase enzyme activity when compared to control groups. Treated larvae underwent an outward morphological change as the result of a decrease in the exterior cuticle of the anal papillae and a demelanization of the interior cuticle. Treated larvae also exhibited abnormal feeding behaviors as a consequence of the negative impact of conidia treatment on the neuromuscular system. Investigation into the effect of M. anisopliae on the non-target organism, the earthworm Eudrilus eugeniae, revealed that M. anisopliae conidia did not produce significant pathogenicity following three days of treatment. Furthermore, histological analysis revealed no significant effect of the entomopathogenic fungi on the gut tissue of the non-target organism.ConclusionThis study highlights the potential of M. anisopliae in the control of S. frugiperda.
