Abstract This study examined the impact of Metarhizium anisopliae (Hypocreales: Clavicipitaceae) conidia on eggs, larvae, pupae, and adults Spodoptera frugiperda . The results showed that exhibited mortality rates were dependent dose. An increased amount (1.5 × 10 9 conidia/mL) was found to be toxic after days treatment, resulting in a 100% rate 98% 76% 85% adults. A using earthworms as bioindicators 3 exposure, M. did not cause any harmful effects earthworms. In contrast, chemical treatment (positive control) resulted at concentration 40 ppm.

The incorporation of green and sustainable nanomaterials in pesticide formation is an effective method to lower the use conventional pesticides without adverse effects on productivity. Here Pickering emulsions stabilized by halloysite nanotubes (HNTs) were developed for low cost, less environmental pollution, toxic effects, better emulsion stability. HNTs added chlorantraniliprole (CAP) emulsions, good stability was exhibited due adsorption aggregation at interface CAP oil droplets, forming a three-dimensional network structure that prevented from aggregation. In addition, Spodoptera frugiperda used as pest model corn plant explore washout resistance, insecticidal effect, biological safety HNTs–CAP emulsion. After spraying leaves washing 10 min, (5 wt % HNTs) residue rate 2.7 times pristine When HNT dispersion concentration 2 %, larva mortality 83%, which 1.5 group. These results demonstrated showed foliar adhesion, rainfall effect. tubular clay-based nanopesticide formulations show potential applications control crop pests with modern agriculture technology.

Insect pests represent a major threat to human health and agricultural production. With current over-dependence on chemical insecticides in the control of insect pests, leading increased resistance target organisms, as well side effects nontarget wider environment, health, finding alternative solutions is paramount. The employment entomopathogenic fungi one such potential avenue pursuit greener, more target-specific methods pest control. To this end, present study tested constituents Metarhizium anisopliae against unicellular protozoan malaria parasite Plasmodium falciparum, Anopheles stephensi Listen, Spodoptera litura Fabricius, Tenebrio molitor Linnaeus, bioindicator species, Eudrilus eugeniae Kinberg. Fungal crude molecules caused noticeable anti-plasmodial effect P. with IC50 IC90 values 11.53 7.65 µg/mL, respectively. significant larvicidal activity LC50 LC90 49.228-71.846 µg/mL A. stephensi, 32.542-76.510 S. litura, 38.503-88.826 T. at 24 h posttreatment. Based results bioassay, it was revealed that fungal-derived extract exhibited no histopathological sublethal earthworm E. eugeniae. LC-MS analysis M. anisopliae-derived metabolites presence 10 constituents. Of these chemicals, three constituents, namely, camphor (15.91%), caprolactam (13.27%), monobutyl phthalate (19.65%), were highlighted for insecticidal anti-malarial activity. extracts thus promising tools malarial parasites.

Entomopathogenic fungi from microbial sources are a powerful tool for combating insecticide resistance in insect pests. The purpose of the current study was to isolate, identify, and evaluate bag-formulated entomopathogenic fungal conidial virulence against We further investigated enzymatic responses induced by as well effect on non-target species. were isolated Palamalai Hills, India, using bait method, Metarhizium majus (MK418990.1) entomopathogen identified biotechnological techniques (genomic DNA isolation 18S rDNA amplification). Bag-formulated efficacy (2.5 × 103, 2.5 104, 105, 106, 107 conidia/ml) evaluated third instar larvae Spodoptera frugiperda at 3, 6, 9, 12 days treatment, acid alkaline phosphatases, catalase, superoxide dismutase 3 post-treatment. After assays earthworm Eudrilus eugeniae performed an artificial soil assay. Results bag formulated treatment showed that S. had high susceptibility rates higher concentrations M. majus. Lower concentration 103 conidia/ml caused 68.6% mortality, while 100% mortality 9 post treatment. Investigation into revealed conidia exposure conidia/ml), enzyme levels significantly changed, with catalase enzymes reduced raised relative control. no sublethal effects observed E. eugeniae, damage gut tissues including lumen epithelial cells, nucleus, setae, coelom, mitochondria, muscles. This offers support use target-specific control

Background ‘The fall armyworm, Spodoptera frugiperda ’, represents a significant threat to maize production, major staple crop in Asian countries. Methods In pursuit of more effective control this insect pest, our study assessed the physiological and biochemical effects entomopathogenic fungus Metarhizium anisopliae against larvae S. . Results revealed that, following nine days treatment, high concentration conidia (1.5x10 7 conidia/mL -1 ) was toxic all stages (second fifth instar), resulting 97% mortality second instar, 89% third 77% fourth 72% instar. All larval instars were found have dose-dependent effects. Treated further displayed physiological, morphological, behavioral changes. Here, treated significantly lower levels acetylcholinesterase, α-carboxylesterase, β-carboxylesterase enzyme activity when compared groups. underwent an outward morphological change as result decrease exterior cuticle anal papillae demelanization interior cuticle. also exhibited abnormal feeding behaviors consequence negative impact treatment on neuromuscular system. Investigation into effect M. non-target organism, earthworm Eudrilus eugeniae , that did not produce pathogenicity three treatment. Furthermore, histological analysis no fungi gut tissue organism.

Abstract Entomopathogenic fungi are the most effective control remedy against a wide range of medical and agricultural important pests. The present study aimed to isolate, identify, assess virulence Metarhizium rileyi Spodoptera litura frugiperda pupae under soil conditions. biotechnological methods were used identify isolate as M. . fungal conidial pathogenicity (2.0 × 10 7 , 2.0 8 9 11 conidia/mL −1 ) was tested prepupae S. at 3, 6, 9, 12 days after treatments. Additionally, artificial soil‐conidial assay performed on nontarget species earthworm Eudrilus eugeniae using conidia. results showed that caused significant mortality rates in (61‐90%), more susceptible than (46%–73%) day posttreatment. LC 50 90 3.4 14 –9.9 17 6.6 5 –4.6 respectively. conidia did not exhibit any sublethal effect adult stage E. Artemia salina following 12‐day treatment period. Moreover, histopathological evaluation no discernible harm observed gut tissues including lumen epithelial cells, well muscles, setae, nucleus, mitochondria, coelom. findings provide clear evidence can be foundation for development bio‐insecticides combat
