Abstract Climate change has increased the susceptibility of forest ecosystems, resulting in escalated decline globally. As one largest biomasses Northern Hemisphere, Eurasian boreal forests are subjected to frequent drought, windthrow, and high-temperature disturbances. Over last century, bark beetle outbreaks have emerged as a major biotic threat these forests, extensive tree mortality. Despite implementing various management strategies mitigate populations reduce mortality, none been effective. Moreover, altered disturbance regimes due changing climate facilitated success attacks with shorter multivoltine life cycles, consequently inciting more beetle-caused This review explores population dynamics context change, stand dynamics, strategies. Additionally, it examines recent advancements like remote sensing canine detection infested trees focuses on cutting-edge molecular approaches including RNAi-nanoparticle complexes, RNAi-symbiotic microbes, sterile insect technique, CRISPR/Cas9-based methods. These diverse novel potential effectively address challenges associated managing beetles improving health response climate.

Oligonucleotide insecticides (contact unmodified antisense DNA biotechnology) and RNA biocontrols (double-stranded RNA technology): newly born fraternal twins in plant protection

Abstract The rapid development of molecular genetics, methods synthesis nucleic acids, and bioinformatics have created fundamentally new opportunities in plant protection. DNA RNA become active ingredients insecticides, going beyond their usual role as carriers hereditary information. Now acids are increasingly acting tools for insect pest control using the mechanisms containment (oligonucleotide contact unmodified antisense (CUAD) biotechnology) interference (RNA biocontrols, double-stranded biotechnology). Partial understanding how oligonucleotides might work began late 1970s XX century a long time (until beginning XXI century) these biomolecules had not been implemented protection form any biotechnology based on or modified fragments. was discovered 90s also went through quite path before first encouraging results its application insecticides appeared. Both, CUAD technology aim to inactivate expression genes pests that help trigger degradation target RNA. As two classes next-generation products supposed operational life, low carbon footprint, high selectivity action biodegradation ecosystems. To date, shows best sap-sucking insects while insecticidal potential beetles from Tenebrionidae Chrysomelidae families. With probability, oligonucleotide will be effective against certain groups can complement each other complex formulations wide range pests.

Towards a unified approach in managing resistance to vaccines, drugs, and pesticides

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 14, 2025

ABSTRACT Everywhere, pests and pathogens evolve resistance to our control efforts, impairing human health welfare. Developing sustainable solutions this problem requires working with evolved immune ecological systems, rather than against these evolutionary forces. We advocate a transdisciplinary approach based on an foundation informed by the concepts of integrated pest management One Health. Diverse, multimodal approaches create more challenging environment for evolution resistance. Given permanent relationships pathogens, responses most biological threats agriculture should seek harm reduction eradication.

Omics Approaches in Understanding Insecticide Resistance in Mosquito Vectors

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(5), P. 1854 - 1854

Published: Feb. 21, 2025

In recent years, the emergence of insecticide resistance has been a major challenge to global public health. Understanding molecular mechanisms this phenomenon in mosquito vectors is paramount for formulation effective vector control strategies. This review explores current knowledge through omics approaches. Genomic, transcriptomic, proteomic, and metabolomics approaches have proven crucial understand these resilient vectors. Genomic studies identified multiple genes associated with resistance, while transcriptomics revealed dynamic gene expression patterns response exposure other environmental stimuli. Proteomics offer insights into protein metabolic pathways involved detoxification resistance. Integrating data holds immense potential expand our on basis mosquitoes via information obtained from different platforms regulatory differential protein, identify transcription factors novel molecules insecticides. Eventually, will help construct predictive models, strategies, develop targeted interventions vector-borne diseases.

Transcriptional signature of host shift in the seed beetle Zabrotes subfasciatus

Genetics and Molecular Biology, Journal Year: 2024, Volume and Issue: 47(1)

Published: Jan. 1, 2024

In phytophagous insects, adaptation to a new host is dynamic process, in which early and later steps may be underpinned by different features of the insect genome. Here, we tested hypothesis that this process are shift gene expression patterns. We set up short-term artificial selection experiment (10 generations) for use an alternative (Cicer arietinum) on populations bean beetle Zabrotes subfasciatus. Using Illumina sequencing young adult females, show selected differ genes associated stimuli, signalling, developmental processes. Particularly, “C. arietinum” population shows upregulation histone methylation genes, constitute strategy fine-tuning global network. qPCR body regions, demonstrated “Phaseolus vulgaris” upregulates polygalacturonase egalitarian odorant receptor transcript variant changes over generations. Moreover, detected existence vitellogenin (Vg) variants both males possibly harbouring canonical reproductive function females extracellular unknown functions males. This study provides basis future genomic investigations seeking shed light nature proximate mechanisms involved promoting differential development hosts.

Abstract Sustainable and effective means to control flying insect vectors are critically needed, especially with widespread insecticide resistance global climate change. Understanding controlling requires accurate information about their movement activity, which is often lacking.
