Because of its extensive damages on mulberry leaves and making obstacle in sericulture, it is inevitable application of synthetic and biorational insecticides. Excessive application of insecticides may lead to develop resistance and to pollute environment mainly water resources therefore use of natural products (like botanical insecticides) is of great importance as an alternative. In the present study, a saponin was extracted from tea seeds and treated against <em>G. pyloalis</em> larvae. Results showed that a concentration of 2.8 % saponin caused 50 % mortality in treated larvae compared to the control, and the LT<sub>50</sub> (Median Lethal Time) was 6.34 days. Also, the repellency index increased in a dose-dependent manner. Tea saponin treatment increased the duration of egg hatching, larval and pre-pupae periods compared to the control. Activities of digestive carbohydrates and proteases were significantly reduced in the exposed larvae. Additionally, saponin treatment significantly decreased the activity of digestive enzymes but it statistically induced antioxidant system in <em>G. pyloalis</em> larvae. The obtained results suggested that tea saponin can affect important biological and physiological processes of <em>G. pyloalis</em> and it may be used as an efficient biopesticide in control of <em>G. pyloalis</em> population.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 4","pages":"Article 102465"},"PeriodicalIF":1.3,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145221180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A hallmark characteristic of ascovirus infection in larvae is reduced feeding and retarded growth. However, the mechanisms by which ascoviruses regulate these effects remain largely unknown. Given their crucial role in regulating larval feeding, insect neuropeptides have attracted our attention in the context of ascovirus infection. During HvAV-3h infection in <em>S. litura</em>, the expression levels of <em>neuropeptide F</em> (<em>NPF</em>), including <em>NPF1</em> and <em>NPF2</em>, which are integral to feeding regulation, were significantly reduced. HvAV-3h infection impaired <em>NPF</em> regulation in larvae, leading to reduced food intake and larval weight gain across different physiological states. Concurrently, significant up-regulation of the <em>NPF</em> receptor (<em>NPFR</em>) was observed in the head tissue. The observed dysregulation of the <em>NPF</em>/<em>NPFR</em> signaling pathway was associated with elevated juvenile hormone (JH) titers. In contrast, the expression levels of <em>short neuropeptide F</em> (<em>sNPF</em>) and the molting hormone ecdysone remained unchanged. Moreover, histopathological analysis of the midgut revealed no epithelial cell damage. Furthermore, RNA interference of <em>NPF1</em> or <em>NPF2</em> significantly increased the expression of <em>NPFR</em> and <em>juvenile hormone acid O-methyltransferase</em> (<em>JHAMT</em>), and tended to further reduce food intake and weight gain, which consequently increased the mortality during HvAV-3h infection. HvAV-3h infection disrupts the <em>NPF</em>/<em>NPFR</em> signaling pathway in <em>S. litura</em> larvae, subsequently elevating JH titers, ultimately leading to reduced food intake and larval weight gain. This study enhances our understanding of the interaction between HvAV-3h and its host, and provides a theoretical basis for the development of innovative pest management strategies.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 3","pages":"Article 102458"},"PeriodicalIF":1.3,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144852231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subsequent medium-pressure liquid chromatography (MPLC) fractionation of the extract produced five fractions, one of which showed antifeedant activity at 125.0 ppm. This active fraction contained high levels of camelliasaponins A1 (5,031 ± 286 ppm) and A2 (6,053 ± 185 ppm). Authentic camelliasaponin A1 and A2 also showed potent antifeedant activity against <em>P. xylostella</em> larvae, with AFC<sub>50</sub> values of 5.4 ppm and 3.6 ppm, respectively—both lower than that of neem-derived Azadirachtin (AFC<sub>50</sub> = 12.4 ppm). These findings confirm that camelliasaponins A1 and A2 are the principal active antifeedant constituents in <em>C. japonica</em> seed extracts. Overall, the findings highlight the potential of camellia seed extracts for development into environmentally friendly formulations for integrated pest management targeting lepidopteran larvae.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 3","pages":"Article 102453"},"PeriodicalIF":1.3,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144827507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
