纳米“药浴”让蜱虫丧失吸血能力 **本报讯（记者李晨 通讯员徐琪明）**近日，中国农业科学院上海兽医研究所动物寄生虫与生物媒介控制团队利用纳米载体，把一种能“关掉”蜱虫关键基因的小分子包裹起来，仅需“喷一喷、泡一泡”，即可让蜱虫吸不了血。相关研究成果发表于《昆虫科学》。 蜱虫是叮咬人畜、传播疾病的“吸血鬼”，可引起发热伴血小板减少综合征、莱姆病等。由于蜱虫体表有一层坚硬外壳，外源双链RNA既无法穿透外壳进入蜱体，又容易被降解，直接“药浴”几乎无效。 科研人员找到蜱虫的一个“命门”基因——蜕皮激素受体基因，它控制着蜱虫的蜕皮、吸血和繁殖，关闭后蜱虫就无法生存。利用纳米材料给该基因的双链RNA穿上“保护衣”，既防止降解，又能帮助它穿透蜱虫外壳。其中一种星型阳离子聚合物纳米载体效果最佳，浸泡后蜱虫靶标基因表达显著下降，饱血率和体重均明显下降，杀蜱虫效果显著。 该研究为开发安全高效的生物杀蜱制剂奠定了基础。

China","https:\u002F\u002Fdoi.org\u002F10.3389\u002Ffsufs.2026.1880869","Introduction The adoption of green agricultural production technologies is critically associated with agricultural green transition, yet sustained adoption remains a persistent challenge under single-governance models. Methods This study constructs a theoretical analysis framework based on the Stimulus-Organism-Response (SOR) theory. Utilizing the Ordered-Probit model, mediation effect model, and fuzzy-set Qualitative Comparative Analysis (fsQCA), and drawing on micro-survey data from 332 tea farmers in Fujian Province, China, this study explores the statistically associated mechanisms and pathways through which the statistical interaction and configurational patterns of the “proactive government + efficient market” are related to farmers’ sustained adoption intention of biopesticide technologies. Results The findings reveal the following: (1) The statistical interaction term of “proactive government + efficient market” shows a significantly positive associated with farmers’ sustained adoption intention of biopesticide technologies, and its estimated synergistic pattern exhibits a nonlinear gain of “1 + 1 > 2” in the regression model. (2) Perceived value statistically mediates the relationship between the statistical interaction of proactive government and efficient market and farmers’ sustained adoption intention of biopesticide technologies, accounting for 20.60% of the total association, and there are significant differences in the mediating roles of the three sub-dimensions. The mediating role of perceived social value is the strongest (33.33%), followed by perceived economic value (15.32%), while perceived ecological value does not serve as a significant mediator. (3) Neither a proactive government nor an efficient market is a necessary condition associated with farmers’ high and sustained adoption intention of biopesticide technologies. The configuration pathways associated with farmers’ high and sustained adoption intention of biopesticide technologies can be categorized into three types: the government - market synergy pathway, the government incentive pathway driven by the market, and the market guidance pathway supported by the government. Discussion It is essential not only to support the incentive role of the proactive government and improve the guiding role of the efficient market but also to construct a dual-wheel-driven synergy mechanism of “proactive government + efficient market” from a collaborative perspective and to enhance the cultivation of farmers’ perceived value, thereby supporting the sustained adoption intention of green production technologies among farmers.","引言 绿色农业生产技术的采用与农业绿色转型密切相关，但在单一治理模式下，持续采用仍然是一项长期挑战。方法 本研究基于刺激—有机体—反应（SOR）理论构建理论分析框架，运用有序Probit模型、中介效应模型和模糊集定性比较分析（fsQCA），并基于中国福建省332户茶农的微观调查数据，探讨“有为政府+有效市场”的统计交互与组态模式同农户生物农药技术持续采用意愿之间统计关联的机制与路径。结果 研究发现如下：（1）“有为政府+有效市场”的统计交互项与农户生物农药技术持续采用意愿显著正相关，其估计的协同模式在回归模型中表现出“1+1>2”的非线性增益。（2）感知价值在有为政府与有效市场的统计交互同农户生物农药技术持续采用意愿之间起统计中介作用，占总关联的20.60%，且三个子维度的中介作用存在显著差异。感知社会价值的中介作用最强（33.33%），其次是感知经济价值（15.32%），而感知生态价值未起显著中介作用。（3）有为政府和有效市场均不是农户生物农药技术高持续采用意愿的必要条件。与农户生物农药技术高持续采用意愿相关的组态路径可归纳为三种类型：政府—市场协同路径、市场驱动的政府激励路径，以及政府支持的市场引导路径。讨论 不仅要支持有为政府的激励作用、提升有效市场的引导作用，还应从协同视角构建“有为政府+有效市场”的双轮驱动协同机制，并提升培育……","Frontiers in Sustainable Food
