The hazardous pest known as rice leaf roller ( Wlk.) (Lepidoptera: Pyralidae), which undermines rice ( L.) output globally, folds the leaves of the rice plant. Protein elicitors are thought to be biological elements that causes the rice to become resistant to herbivores. The potential for biocontrol of the emerging elicitor protein evaluated from 2 (PeVL1) was evaluated against . To assess the impact of PeVL1 on immature development, survival, and lifetime, four different PeVL1 concentrations were allocated. Electrical penetration graphs (EPGs) against were used to evaluate adult reproductive efficiency and the interaction between the pest and the pathogen. Furthermore, the characterization of active substances in PeVL1 with multi-acting entomopathogenic effects looked into the direct interactions of PeVL1 with temperature and climatic change in rice () plants. PeVL1 treatments reduced the population increase of second and third generation compared to controls. In a test of host selection, colonized control plants more quickly than PeVL1-treated plants. PeVL1 concentrations prolonged the larval stage. Similar to fecundity, PeVL1-treated seedlings produced fewer offspring than control seedlings. On PeVL1-treated leaves, trichomes and wax production created an unfavorable habitat for . PeVL1 changed the surface structure of the leaves, which inhibited colonization and decreased reproduction. The activation of pathways was another aspect of systemic defense activities including jasmonic acid (JA), salicylic acid (SA), and ethylene (ET). Based on these results against , the use of PeVL1 in the agroecosystem with integrated pest management and biocontrol seems appropriate. Our research provides a novel insight into a cutting-edge biocontrol method utilizing 2.
稻纵卷叶螟（Wlk.）（鳞翅目：螟蛾科）是一种有害害虫，它会破坏全球水稻（L.）的产量，会将水稻植株的叶片卷起。蛋白质激发子被认为是使水稻对食草动物产生抗性的生物因子。对从2（PeVL1）中评估的新型激发子蛋白进行生物防治的潜力进行了评估，以对抗[此处原文缺失对抗对象]。为了评估PeVL1对未成熟发育、存活和寿命的影响，分配了四种不同的PeVL1浓度。使用针对[此处原文缺失对象]的电穿透图（EPGs）来评估成虫的繁殖效率以及害虫与病原体之间的相互作用。此外，对具有多种昆虫致病作用的PeVL1中的活性物质进行表征，研究了PeVL1与水稻（）植株中温度和气候变化的直接相互作用。与对照相比，PeVL1处理降低了第二代和第三代[此处原文缺失对象]的种群增长。在宿主选择试验中，[此处原文缺失对象]在对照植株上定殖的速度比经PeVL1处理的[此处原文缺失对象]植株更快。PeVL1浓度延长了[此处原文缺失对象]的幼虫期。与繁殖力类似，经PeVL1处理的幼苗产生的后代比对照幼苗少。在经PeVL1处理的叶片上，毛状体和蜡质的产生为[此处原文缺失对象]创造了不利的栖息地。PeVL1改变了叶片的表面结构，抑制了定殖并降低了[此处原文缺失对象]的繁殖。包括茉莉酸（JA）、水杨酸（SA）和乙烯（ET）在内的系统防御活动的另一个方面是信号通路的激活。基于这些针对[此处原文缺失对象]的结果，在综合害虫管理和生物防治的农业生态系统中使用PeVL1似乎是合适的。我们的研究为利用2的前沿生物防治方法提供了新的见解。
