Hemiptera is one of the most significant orders insect pests, including whiteflies, true bugs, aphids, planthoppers, psyllids, and so forth, which have led to substantial economic losses in agricultural industries significantly affected food yields through their ability suck phloem sap crops transmit numerous bacterial viral pathogens. Therefore, explorations pest-specific, eco-friendly easy-to-adopt technologies for hemipteran pest control are urgently needed. To best our knowledge, microRNAs (miRNAs), endogenous non-coding small RNAs approximately 22 nucleotides length, involved regulating gene expression via direct recognition binding 3'-untranslated region (3'-UTR) target messenger (mRNAs) or by acting as a center competitive RNA (ceRNA) network at post-transcriptional level. This review systematically outlines characterization functional investigation miRNA biogenesis pathway such aphids planthoppers. In addition, we explored results sequencing observations miRNAs these suggest that obtained annotated high-throughput technology bioinformatic analyses contribute molting development, fitness, wing polyphenism, symbiont interactions insecticide resistance pests. Finally, summarize current advances propose framework future research extend data address potential limitations application miRNAs.

Piezodorus guildinii (Westwood, Hemiptera: Pentatomidae) causes economic losses in soybean crops by diminishing productivity, impacting grain size, oil content, and germination power. RNA interference (RNAi), a conserved gene regulation process initiated double-stranded (dsRNA), may be used as safe technique integrated pest management strategies. Conjugating dsRNA with cationic polymers, which protect from degradation has shown to enhance this response. This study aims assess the impact of administration on viability P. evaluate dsRNA-chitosan nanocomplexes control strategy. Ten target genes were selected, dsRNAs designed synthesized. In injection assays, significant mortality exceeding 76% was observed, while ingestion also showed differences, reaching 49%. The targeting Srp54k selected chitosan-dsRNA nanocomplex These demonstrated enhanced stability under RNase treatment vitro, and, vivo cumulative corrected rate 66% reported. Consistent these findings, RT-qPCR analysis revealed that expression levels treated insects significantly reduced compared at 24, 48, 72 h post for targeted genes. work, we evaluated effect determined its molecular silencing effects. Additionally, synthesized characterized nanoparticles, improved efficacy terms stability. findings are promising development new strategies stink bugs control. © 2025 Society Chemical Industry.

The mirid bug Apolygus lucorum, a dominant species in northern China, is notorious polyphagous pest with more than 200 hosts, including several major crops such as cotton and soybean, resulting massive economic loss. Studies of insect salivary effectors may provide novel control strategy for A. lucorum. An lucorum effector, that is, Al6, inhibits plant immunity by using glutathione peroxidase to repress reactive oxidase accumulation was previously identified. In this study, we further explored the molecular functions Al6 associated feeding behaviour survival on host RNA interference electrical penetration graph (EPG) techniques. We initially observed injury symptom characterized soybean leaves EPG. Our results revealed preferred feed young organs tender leaves, shoots buds. This used cell rupture ingest contents from tissues. Subsequently, silenced gene RNAi investigated behaviour, honeydew excretion, body weight, rates after knockdown. demonstrated silencing significantly reduced duration, amount secretion, Thus, our findings target plant-mediated

Abstract The redbanded stink bug (RBSB), Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) is an invasive species and a polyphagous pest of cultivated crops non-cultivated wild plants. increase in soybean cultivation during the 1960s–1970s led to spread RBSB as economic throughout South America, especially Brazil, Argentina, Uruguay. In early 2000s, became concern US agriculture currently key complex that damages many mid-southern states. causes extensive damage soybeans other economically important leguminous by feeding on sap from stems, flowers, foliage with preference for pods seeds, which flat pods, reduced seed weight, germination. Infestation may lead more crop loss per capita than species. RBSBs are less susceptible commonly used agrochemicals have developed resistance insecticides. Several alternative control strategies based wide variety methods been reported recent years. This review will discuss distribution, biology, ecology, various integrated management last 2 decades.
