The fall armyworm, Spodoptera frugiperda (Noctuidae; Lepidoptera), is a serious threat to food security as it has the potential feed on over 353 plant species. To control this insect pest, endophytic colonization of entomopathogenic fungi (EPF) in plants being considered safer and more effective alternative. This study evaluated efficacy two EPFs, Beauveria bassiana Metarhizium anisopliae, for using foliar spray seed treatment methods maize plants, their impact survival, development, fecundity S. frugiperda. Both EPF effectively colonized with methods, resulting 72–80% 50–60% rates, respectively, 14 days after inoculation. negatively impacted development Larvae feeding EPF-inoculated leaves had slower (21.21 d M. anisopliae 20.64 B. bassiana) than (20.27 d). rate was also significantly reduced 260.0–290.1 eggs/female both applications compared (435.6 eggs/female). Age-stage-specific parameters showed lower fecundity, life expectancy, survival when they fed untreated leaves. Furthermore, EPFs significant effect population such intrinsic (r = 0.127 d−1 bassiana, r 0.125 anisopliae) finite (λ 1.135 λ 1.1333 0.133 1.146 d−1). These findings suggest that can be used Therefore, these should integrated into pest management programs pest.

Cydia pomonella L. is a highly destructive pest inflicting substantial damage on pome fruits globally. Resistance to chemical pesticides by C. poses significant challenge the effective management strategies. Utilising entomopathogenic fungi (EPF) for of insect pests has emerged as one promising and environmentally friendly alternatives. Against this backdrop, we conducted laboratory bioassays assess efficacy three EPF, namely Beauveria bassiana (Bals.-Criv.) Vuill., Cordyceps fumosorosea (Wize) Metarhizium anisopliae (Metschn.) Sorokīn against using concentrations (1 × 104, 1 105, 106 conidia/ml). Highest larval (98.62 ± 10.00%) pupal (37.35 2.15%) mortality was observed when treated with B. while lowest (51.55 6.30%) (17.83 7.28%) seen in fumosorosea. Maximum adult emergence (16.26 3.24) recorded minimum (5.72 0.09) bassiana. LC50 values fumosorosea, M. were 5.482, 2.683 1.891 conidia/ml, respectively. All tested EPF under controlled conditions.

Abstract Invasive alien insects have the potential to pose a significant threat global agriculture, with their distinctive traits enabling rapid reproduction, successful adaptation new environments and high distribution capability. These pests can devastate crops, livestock, biodiversity ecosystem functioning, resulting in ecological damage substantial economic losses. Climate change plays crucial role driving invasion of these pests, creating favorable conditions for development, negatively impacting biodiversity. Among invasive insects, fall armyworm (FAW) ( Spodoptera frugiperda ) (JE Smith) (Lepidoptera: Noctuidae) has emerged as major pest species, causing yield losses maize cropping outside his native range. Initially, reliance on pesticides control proved ineffective led pesticide resistance. Significant progress been made implementing integrated management (IPM) strategies that integrate agro-ecological biological approaches. This review article focuses compilation IPM methods, combining practices agents such parasitoids viruses, effective FAW. Approaches intercropping, agronomic practices, use viruses shown promising results controlling provides insights into recommendations suggestions sustainable FAW using or combination.

Abstract The role of pathogens in the successful invasion pests has received increasing attention. Previous hypotheses on parasite‐related mainly focus lack parasites against invasive or introduction with a higher risk to native pests. Fall armyworm (FAW), Spodoptera frugiperda (J.E.

Here, we investigated pathogen infection eight natural populations FAW China, isolated and characterised pathogens, then evaluated frequencies were very low (0.32%); only two individuals found have typical symptoms fungal infection, fungi identified as Beauveria bassiana Metarhizium rileyi . Internal transcribed spacer sequence‐based analysis showed that among 44 B. isolates worldwide, SFJS01 isolate was genetically different from 3 isolates. Among all 13 M.

Background The fall armyworm, Spodoptera frugiperda , is an agricultural pest of significant economic concern globally, known for its adaptability, pesticide resistance, and damage to key crops such as maize. Conventional chemical pesticides pose challenges, including the development resistance environmental pollution. study aims investigate alternative solution: application soluble silicon (Si) sources enhance plant against armyworm. Methods Silicon dioxide (SiO 2 ) potassium silicate (K SiO 3 were applied maize plants via foliar spray. Transcriptomic biochemical analyses performed gene expression changes in armyworm feeding on Si-treated Results indicated a impact expression, with large number differentially expressed genes (DEGs) identified both K treatments. Furthermore, Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) enrichment analysis critical DEGs involved specific pathways, amino acid, carbohydrate, lipid, energy, xenobiotics metabolisms, signal transduction, posttranslational modification, significantly altered at Si sources. Biochemical further revealed that treatments inhibited several enzyme activities (glutamate dehydrogenase, trehalase, glucose-6-phosphate chitinase, juvenile hormone esterase, cyclooxygenase while simultaneously inducing others (total protein, lipopolysaccharide, fatty acid synthase, ATPase, cytochrome P450), thus suggesting toxic effect In conclusion, applications influence potentially offering sustainable management strategy.

Fall Armyworm (FAW), Spodoptera frugiperda (Lepidoptera: Noctuidae) , is a significant pest causing substantial economic losses worldwide, particularly in Sub-Saharan Africa. The prevalent strategy for managing FAW involves insecticide applications, ranging from synthetic to botanical and microbial agents. However, the ecological impacts of these interventions often remain unassessed. This study scrutinizes viability two insecticidal treatments: one based on emamectin benzoate another comprising combination Pieris rapae granulovirus (PrGV) Bacillus thuringiensis subsp. kurstaki (Btk) with varied application timings frequencies. Our findings indicate that both types were effective reducing larval populations associated crop damage. From an standpoint, PrGV|Btk treatment enhanced parasitism rates, especially when applied only at early stage crop. this approach did not significantly lower damage compared "targeted" strategy, where was contingent upon observed injury levels. Remarkably, led increased parasitism, V7 growth Economically, emerged as efficient, minimizing need multiple sprays thus recommended infestations while considering cost balance.
