Agronomy, Год журнала: 2022, Номер 12(9), С. 2150 - 2150

Опубликована: Сен. 9, 2022

The fall armyworm of maize, Spodoptera frugiperda (J. E. Smith) (Lepidoptera; Noctuidae) is capable causing a 100% yield loss due to its unforeseen occurrence from the seedling cob formation stage. To manage this serious pest, maize growers are tending apply high dosage pesticides. This indiscriminate usage pesticides has resulted in an unacceptable amount insect resurgence harming production and consumption. In review, we prepared list practical pest management options, including host plant resistance, agronomical, cultural, biological, botanical, chemical, biotechnology approaches. It was found that cultivation tolerant genotypes, adjusting sowing windows, practicing specific intercultural cropping systems measures addition chemical non-chemical strategies showed encouraging results for sustainable armyworm, which could protect crop. review highlights novel successful options advocated various parts world. Recommendations documented paper would certainly pave way other concerned crops.

CRISPR/Cas9 for Insect Pests Management: A Comprehensive Review of Advances and Applications

Agriculture, Год журнала: 2022, Номер 12(11), С. 1896 - 1896

Опубликована: Ноя. 10, 2022

Insect pests impose a serious threat to agricultural productivity. Initially, for pest management, several breeding approaches were applied which have now been gradually replaced by genome editing (GE) strategies as they are more efficient and less laborious. CRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeat/CRISPR-associated system) was discovered an adaptive immune system of bacteria with the scientific advancements, it has improvised into revolutionary technique. Due its specificity easy handling, CRISPR/Cas9-based wide range organisms various research purposes. For control, diverse utilizing CRISPR/Cas9-like systems, thereby making susceptible insecticides, compromising reproductive fitness pest, hindering metamorphosis there many other benefits. This article reviews efficiency proposes potential ideas integrated management. technology successfully insect species. However, is no review available thoroughly summarizes application technique in control. Further, authors highlighted advancements discussed future possibilities

Knockout of a testis‐specific gene cluster impairs male fertility in the fall armyworm, Spodoptera frugiperda

Pest Management Science, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

The function of some testis-specific genes (TSGs) in model insects have been studied, but their non-model remains largely unexplored. In the present study, we identified several TSGs fall armyworm (FAW), a significant agricultural pest, through comparative transcriptomic analysis. A gene cluster (TSGC) comprising multiple functional and long non-coding RNAs was found. Quantitative PCR analysis validated expression within this across different developmental stages. Interspecies collinearity indicated that TSGC is conserved among lepidopterans. To elucidate TSGC, employed CRISPR/Cas9 gene-editing technique to generate loss-of-function mutants. Notably, hatching rate eggs produced by wild-type females mated with mutant males (approximately 30%) substantially lower than from 80%). Additionally, reduction size number sperm observed testis compared males. Collectively, study not only elucidates role supporting male fertility FAW, which provides valuable information for understanding mechanism reproduction insects, also identifies potential target development genetic control strategies against lepidopteran pests. © 2025 Society Chemical Industry.

CRISPR-Cas Genome Editing for Insect Pest Stress Management in Crop Plants

Stresses, Год журнала: 2022, Номер 2(4), С. 493 - 514

Опубликована: Дек. 7, 2022

Global crop yield and food security are being threatened by phytophagous insects. Innovative methods required to increase agricultural output while reducing reliance on hazardous synthetic insecticides. Using the revolutionary CRISPR-Cas technology develop insect-resistant plants appears be highly efficient at lowering production costs increasing farm profitability. The genomes of both a model insect, Drosophila melanogaster, major insect genera, viz. Spodoptera, Helicoverpa, Nilaparvata, Locusta, Tribolium, Agrotis, etc., were successfully edited toolkits. This new method, however, has ability alter an insect’s DNA in order either induce gene drive or overcome tolerance certain rapid progress methodologies CRISPR their diverse applications show high promise development plant varieties other strategies for sustainable management pests ensure security. paper reviewed critically discussed use genome-editing long-term pest management. emphasis this review was prospective uses system stress through creation genome-edited potential difficulties using reduce examined discussed.

Advancements and prospects of CRISPR/Cas9 technologies for abiotic and biotic stresses in sugar beet

Frontiers in Genetics, Год журнала: 2023, Номер 14

Опубликована: Ноя. 9, 2023

Sugar beet is a crop with high sucrose content, known for sugar production and recently being considered as an emerging raw material bioethanol production. This also utilized cattle feed, mainly when animal green fodder scarce. Bioethanol hydrogen gas from this essential source of clean energy. Environmental stresses (abiotic/biotic) severely affect the productivity crop. Over past few decades, molecular mechanisms biotic abiotic stress responses in have been investigated using next-generation sequencing, gene editing/silencing, over-expression approaches. information can be efficiently through CRISPR/Cas 9 technology to mitigate effects cultivation. review highlights potential use management beet. Beet genes involved response alkaline, cold, heavy metal precisely modified via enhancing beet’s resilience minimal off-target effects. Similarly, help generate insect-resistant varieties by targeting susceptibility-related genes, whereas incorporating Cry1Ab Cry1C may provide defense against lepidopteron insects. Overall, enhance adaptability challenging environments, ensuring sustainable, high-yield
