Herein, we predicted the physicochemical and structural features of the silkworm SelM. Gene-specific siRNAs were then micro-injected into silkworms fed with sodium selenite (Na<sub>2</sub>SeO<sub>3</sub>) (50 μM). SelM disruption reduced body mass, cocoon weight, cocoon shell weight and shell rate of silkworms, whereas egg production and egg laying mostly remained unchanged. Moreover, sodium selenite (Na<sub>2</sub>SeO<sub>3</sub>) (50 μM) supplementation alone significantly improved growth factors of silkworms, without any obvious effect on egg production and laying. RT-qPCR revealed lowest SelM transcript levels at 24 h post injection, followed by a gradual recovery; among the three siRNAs tested, SelM-244 had the strongest interfering effect. These data demonstrate that SelM is an indispensable component of Se metabolism in silkworms, coupling Se status to silk protein synthesis and larval growth.

Evidence from pilot studies demonstrates that pheromone interventions can reduce pest populations by 35–70 %, and successful integrations have been reported in countries such as Nigeria, Kenya, Ghana, and Benin.

Although their slow pathogenicity limits application, baculoviruses represent a potentially effective alternative for the control of <em>S. exigua</em>. Recently, RNA interference (RNAi) has emerged as a promising strategy for controlling insect pests by silencing essential genes, thereby inducing mortality and reducing insect populations. In this study, exogeneous dsRNAs targeting beta-1-integrin (dsITGB1), AChE1 (dsAChE1), and Apolipophorin III (dsApoLp-III) of <em>S. exigua</em> significantly increased insecticidal activity of <em>Autographa californica</em> multiple nucleopolyhedrovirus (AcMNPV) against <em>S. exigua</em> larvae when they were applied through hemocoelic injection. To improve AcMNPV efficacy, these dsRNA genes were introduced into AcMNPV genome singly or in combination. These recombinant AcMNPVs exhibited enhanced mortality rates, demonstrating that the insecticidal activity of AcMNPV could be enhanced by introducing these dsRNA genes. In particular, these enhancing effects were more evident when dsRNA genes were introduced in combination. These results suggested that dsRNA genes could be useful to enhance insecticidal activity of AcMNPV for environmentally friendly and effective control of <em>S. exigua</em>.</div></div>","PeriodicalId":15094,"journal":{"name":"Journal of Asia-pacific Entomology","volume":"28 4","pages":"Article 102505"},"PeriodicalIF":1.3,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145568789","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}
