Complex biological preparations are of great interest for the acaricide market because they do not poison ecosystems and do not bioaccumulate in food products, simultaneously, pests more slowly develop resistance to complex preparations. In this study we applied complex bioformulation composed of 11-mer antisense oligonucleotide (oligonucleotide acaricide or DNA acaricide) Tur-3 and fungus <em>Metarhizium robertsii</em> for <em>T. urticae</em> control<em>.</em> We discovered that joint contact application of DNA acaricide and fungus <em>M. robertsii</em> significantly attenuates reproduction rate of the mite. Our results indicate that DNA acaricide Tur-3 and fungus <em>M. robertsii</em> act synergistically and lead to a significant 7-times elevated mortality rate and a reduction of 80% in the mite fecundity. Oligonucleotide acaricide Tur-3 causes 2.5-fold reduction of expression of the target pre-rRNA of <em>T. urticae</em> and suppresses the activity of key players of detoxifying enzymes of its defense system (phenoloxidase, esterase, glutathione-S-transferase), on average, by 2–3 fold. Oligonucleotide acaricide Tur-3 interferes with protein biosynthesis causing decrease in production of defense system enzymes of the pest. Obviously, attenuation of defense system enhances fungal infection or/and fungus produces a variety of enzymes that degrade the integument structure of the pest, aiding the penetration of oligonucleotide acaricide Tur-3. This research article is the first evidence of successful application of oligonucleotide acaricide together with fungus <em>M. robertsii</em> for efficient <em>T. urticae</em> control.

Although lipopeptides produced by <em>Bacillus subtilis</em> have been shown to exert strong inhibitory effects against <em>Vibrio parahaemolyticus</em>, the underlying mechanisms remain largely unexplored. This study reveals that the lipopeptide surfactin, produced by <em>Bacillus subtilis</em>, significantly inhibits the V<em>p<sub>AHPND</sub></em> strain JSHY-1669 through multiple mechanisms. Using antagonistic assays and transcriptomic analysis, this paper investigates the molecular mechanisms of surfactin’s inhibitory action on V<em>p<sub>AHPND</sub></em> strain JSHY-1669. The minimum inhibitory concentration (MIC) of surfactin against JSHY-1669 was determined to be 0.125 mg/mL, with a cumulative inhibitory effect. Exposure to surfactin caused significant structural damage to the bacterial cells, markedly inhibiting their growth and virulence gene expression. Transcriptomic analysis identified 64 genes with significant differential expression, including upregulation of genes involved in key metabolic pathways such as carbohydrate transport, and downregulation of non-essential pathways like amino acid and sulfur metabolism. Surfactin affects JSHY-1669 by disrupting key physiological processes. Specifically, it increases cell membrane depolarization, reactive oxygen species (ROS) production, and malondialdehyde (MDA) levels. These changes collectively lead to the loss of membrane integrity, which ultimately inhibits bacterial growth. Additionally, the study found downregulation of slyA, a key regulatory factor related to DNA-binding transcription, virulence regulation, and carbohydrate metabolism. Surfactin may expand its inhibitory range by affecting the slyA regulatory network, providing a basis for surfactin’s broader antibacterial targets. These findings elucidate the inhibitory mechanisms of surfactin on V<em>p<sub>AHPND</sub></em> strain JSHY-1669, laying a foundation for its potential applications.</div></div>","PeriodicalId":16296,"journal":{"name":"Journal of invertebrate pathology","volume":"211 ","pages":"Article 108298"},"PeriodicalIF":3.6,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143561373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spectrum of dependence in this symbiotic partnership is diverse, ranging from a tight, obligate relationship to a facultative one. A body of evidence suggests that the reproductive fitness of the nematode-bacterium partnership is tightly associated and interdependent. Furthermore, maintenance of their virulence is also critical to the conversion of the insect host as a suitable environment where this partnership can be perpetuated. Disruption of the symbiotic partnership can have detrimental effects on the fitness of both partners. The nematode-bacterial symbiont-insect partnership represents a model system in ecology and evolutionary biology and amenable to investigate beneficial and antagonistic interactions between invertebrates and microbes. Furthermore, the EPN’s bacterial symbionts are also viewed as a model system to study the biosynthesis, structure and function of various natural products. Their ability to produce up to 25 different natural product classes is outstanding among the Morganellaceae. These natural products show biological activity, most likely originating from important functions during the life cycle of both the nematodes and their symbionts. Tools and high throughput technologies have been developed to identify ubiquitous and rare molecules and study their function and assess their potential as novel biological activities. We herein summarize the symbiotic relationship between EPN and their bacterial symbionts, focusing on their fitness and their ability to successfully access and utilize an insect host.

In addition to losses associated with feeding, <em>B. tabaci</em> vectors hundreds of plant viruses, many of which cause severe disease in staple food crops. The management of <em>B. tabaci</em> is confounded by extensive resistance to chemical insecticides. While pesticidal proteins derived from entomopathogenic bacteria such as <em>Bacillus thuringiensis</em> (Bt) could provide for alternative management approaches, only one pesticidal protein with toxicity to <em>B. tabaci</em> has been identified. Here we screened 11 Bt-derived pesticidal proteins from several different structural classes against the highly invasive, Middle East-Asian Minor 1 (MEAM1) cryptic species of <em>B. tabaci</em>, and assessed the impact of a <em>B. tabaci</em>-active protein on the gut epithelial membrane by transmission electron microscopy. The pesticidal proteins were expressed in Bt or in <em>Escherichia coli</em> and purified for use in bioassays. The toxicity of purified proteins was first assessed by feeding adults on a single dose followed by lethal concentration (LC<sub>50</sub>) determination for proteins with significant mortality relative to the buffer control. The proteins Tpp78Aa1, Tpp78Ba1, and Cry1Ca were toxic to <em>B. tabaci</em> with LC<sub>50</sub> values of 99, 96, and 351 µg/mL, respectively. Disruption of the brush border and severe reduction in microvilli on the gut surface caused by Tpp78Aa1 is consistent with the mode of action of Bt-derived pesticidal proteins. These proteins may provide valuable tools for the integrated management of <em>B. tabaci</em> populations and associated reduced incidence of <em>B. tabaci</em> vectored plant viral diseases.</div></div>","PeriodicalId":16296,"journal":{"name":"Journal of invertebrate pathology","volume":"210 ","pages":"Article 108291"},"PeriodicalIF":3.6,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143476512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
