To resolve this emerging issue, we initiated a project to develop double-stranded RNA (dsRNA)-based biopesticides against T. urticae, aiming for a species-specific and sustainable pest management alternative.</p><p><strong>Results: </strong>To examine the uptake of dsRNAs using the egg-soaking delivery method, we fluorescently labeled extraneous dsRNAs, and later showed that T. urticae dsRNAs can permeate through eggshell in a time-dependent manner within the first 24 h. For target gene screening, silencing of Prosbeta-1 and -5 resulted in the highest mortality (>90%) and a dark body phenotype in T. urticae. Notably, each target gene was effective in both avermectin laboratory susceptible and field resistant populations.

Chemical insecticides have been applied to control M. usitatus, but have resulted in little profit because of the rapid evolution of insecticide resistance. To characterize the potential insecticide resistance mechanisms in M. usitatus, we sequenced and assembled a chromosome-level genome of M. usitatus by combining PacBio sequencing and Hi-C technology using a susceptible population.</p><p><strong>Results: </strong>The genome size was 248.60 Mb and contained 14 128 protein-coding genes. The expansion genes of M. usitatus were enriched in the functional categories of heme binding and monooxygenase activity. We further identified 103 cytochrome P450 genes from the M. usitatus genome, 33 of which belonged to the CYP6 family. Ten CYP6 genes were significantly overexpressed in an acetamiprid-resistant population of M. usitatus. An RNA interference bioassay showed that knockdown of CYP6FW1, CYP6GM5, CYP6GM6, and CYP6GM7 significantly reduced acetamiprid resistance in the resistant population. In addition, the expression of all four genes could be induced by acetamiprid exposure. AlphaFold2-based homology modeling and molecular docking analysis showed that the proteins with relevance to acetamiprid resistance had relatively lower binding free energy with the acetamiprid molecule.</p><p><strong>Conclusion: </strong>This study provides a reference genome and gene resources for future studies on the evolution of M. usitatus and related pest species, and highlights the importance of cytochrome P450s in insecticide resistance in this pest insect. © 2025 Society of Chemical Industry.</p>","PeriodicalId":218,"journal":{"name":"Pest Management Science","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143062818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the expansion, soybean productivity in Africa remains less than half of the global average. This yield gap is largely due to diseases and pests, such as soybean rust, which can be particularly severe. Effective management of soybean rust depends on several factors, including resistant cultivars. However, there has been limited information on the rust-resistance levels of African cultivars.
