The fall armyworm (FAW) Spodoptera frugiperda, a highly invasive, polyphagous pest, poses global agricultural threat. It has two strains, the C-corn and R-rice each with distinct host preferences. This study compares detoxification enzyme gene families across these strains related species to explore their adaptation diverse plant metabolites. A total of 1,995 detoxification-related genes, including cytochrome P450 monooxygenases (CYPs), carboxylesterases (COEs), glutathione S-transferases (GSTs), UDP-glucuronosyltransferases (UGTs), ATP-binding cassette transporters (ABCs), were identified genus Spodoptera, S. littoralis, litura, picta, exigua, both FAW strains. higher abundance phase I enzymes (CYPs COEs) GSTs was observed in species, while exhibited fewer notable differences copy numbers between C R Analyses at subfamily level revealed significant variation distribution expression, particularly within II enzymes. Expansions CYP6AE detected strain, contractions GST-ε, CYP9A, CYP4M, UGT33B, UGT33F occurred In contrast, no substantial III ABC Functional predictions protein interaction networks suggest broader expansion metabolism-related genes strain compared strain. These findings emphasize pivotal role adaptation, providing molecular insights into FAW's capacity for range expansion, which are crucial devising targeted sustainable pest management strategies. differential expression different frugiperda.

Insecticide resistance is a major problem in food production, environmental sustainability, and human health. The cotton bollworm Helicoverpa armigera globally distributed crop pest affecting over 300 species. H. has rapidly evolved insecticide resistance, making it one of the most damaging pests worldwide. Understanding genetic basis provides insights to develop tools, such as molecular markers, that can be used slow or prevent evolution resistance. We explore architecture widely insecticide, flubendiamide, using two complementary approaches: genome-wide association studies (GWAS) wild-caught samples quantitative trait locus (QTL) mapping controlled cross susceptible resistant laboratory strains. Both approaches identified on chromosome 2, revealing SNPs within 976 bp monitor field flubendiamide. This was only region linkage mapping, though GWAS revealed additional sites associated with Other loci by populations contained known detoxification genes from ATP-binding cassette family, ABCA1, ABCA3, ABCF2 MDR1. Our findings an oligogenic architecture, contrasting previous reports monogenic ryanodine receptor . work elucidates evolving will contribute developing effective management strategies.

Spodoptera frugiperda poses a severe threat to crops, causing substantial economic losses. The increased use of chemical pesticides has led resistance in S. populations. Micro ribonucleic acids (MicroRNAs or miRNAs) are pivotal insect growth and development. This study aims identify miRNAs across different developmental stages explore differential expression predict target gene functions. High-throughput sequencing was conducted on eggs, 3rd instar larvae, pupae, adults. Bioinformatics analyses identified differentially expressed specifically with candidate screened genes, particularly those involved detoxification pathways. A total 184 known 209 novel were stages. Comparative analysis revealed 54, 15, 18 compared egg, pupa, adult stages, respectively. Eight showed significant validated by quantitative reverse transcription PCR (qRT-PCR). Gene Ontology Kyoto Encyclopedia Genes Genomes enrichment predicted genes’ functions, identifying eight targeting 10 families associated metabolism, including P450s, glutathione S-transferase (GSTs), ATP-binding cassette (ABC) transporters, sodium channels. These findings elucidate the species-specific miRNA profiles regulatory mechanisms detoxification-related genes offering insights strategies for effectively managing this pest.

Chemical control methods to prevent crop damage have long been directly implicated in the selection of lepidoptera insect populations resistant insecticides. More recently, new products featuring different modes action (MoA), developed mitigate negative effects management on both producers and environment, are rapidly losing efficacy due emergence insects. Among these, certain resistances associated with molecular changes genomes pest insects that valuable for developing markers diagnostic tools, particularly point mutations. Molecular diagnosis represents an innovative solution insecticide resistance (IRM) practices, allowing effective monitoring resistance. This approach facilitates decision making by enabling timely alternation between (MoAs). In this context, review focuses major lepidopteran pests affect globally significant crops, discussing impacts It gathers literature methods; provides a comparative overview advantages techniques terms efficiency, cost, precision, sensitivity, applicability; highlights several novel tools. Additionally, explores coffee leaf miner, Leucoptera coffeella, as applied model illustrate potential approaches more sustainable strategies.
