在释放天敌昆虫 工作人员 无人机在 进行投放天敌昆虫作业 在农药减量的背景下，一群不起眼的"小虫"正悄然成为田间卫士。 据悉，我市已释放捕食螨等"天敌昆虫"超过200万亩，通过"以虫治虫"可减少30%以上的农药施用，有 效保障农产品的质量安全。 它们如何从实验室走向田间，又如何突破重重困境，撑起一个产业的？记者走进山城的果园与车间，探 寻"以虫治虫"背后的故事与未来。 小虫大功 冬日的阳光斜洒进大棚，草莓叶泛着油亮的绿。北碚区兴隆镇渝兴莓草莓园里，负责人冉红英拧开一个 白色塑料瓶，舀了一小勺"锯末"，轻轻抖落在即将开花的草莓植株叶面上。 "这可是咱的'秘密武器'。"她笑着指了指瓶身标签——捕食螨，每瓶5万只。 种植草莓13年，冉红英与草莓的天敌红蜘蛛斗了多年。7年前，在农技员的推荐下，她第一次尝试以虫 治虫。如今，这罐"小虫"已成为她每年必购的生物农药。 万州区甘宁镇，玫瑰香橙挂满枝头，压弯了绿树。仔细看，不少果树主干上，还挂着一个剪了口的小纸 袋。"这里头住着我们的功臣——捕食螨。"果园负责人朱文祥指着纸袋说，它们专治"果园小强"红蜘 蛛。 红蜘蛛不过芝麻大小，危害却惊人。一只雌虫一年可繁衍十余代，吸食叶片 ...

Core Viewpoint - The increasing public awareness of mosquito prevention is driving the growth of related products and services in the market [3][5]. Group 1: Market Demand and Trends - The demand for mosquito repellent products has surged due to rising temperatures and increased rainfall, leading to a higher incidence of mosquito-borne diseases [3][4]. - In Guangdong, from July 27 to August 2, there were 2,892 new reported cases of local transmission of Chikungunya fever, prompting local governments to initiate mosquito control measures [4]. - Sales of mosquito repellent products in supermarkets have doubled in recent weeks, with overall sales up by 30% compared to July [7][5]. Group 2: Product Development and Consumer Behavior - Consumers are increasingly purchasing mosquito repellent products from supermarkets, with products prominently displayed and marketed with various features such as "baby-friendly" and "outdoor use" [6][7]. - The market for mosquito repellent products is still dominated by traditional items like floral water and incense, with a lack of innovation appealing to younger consumers [8][6]. Group 3: Biological Control Measures - Several cities in South China are experimenting with biological control methods to reduce the transmission of mosquito-borne viruses, including the introduction of non-biting mosquito species and fish that consume mosquito larvae [12][13]. - The "mosquito factory" model, which involves releasing infected male mosquitoes to suppress the population of disease-carrying females, has shown promising results in international contexts [13][14]. Group 4: Recommendations for Public Health - Public health departments are encouraged to adopt proactive measures for mosquito control, including regular supply of necessary products and public awareness campaigns [17][12]. - The cost of implementing biological control measures is estimated to be between 2 to 3 yuan per square meter, with potential for cost reduction as the scale of the project increases [14][16].

Core Insights - The article highlights the integration of advanced technology in agriculture in Liaoning, China, showcasing innovations such as drone-assisted pest control and real-time soil monitoring systems [1][2]. Group 1: Technological Innovations in Agriculture - The "Cloud Farm" system developed by Tieling Mobile Company allows real-time monitoring of soil moisture, water quality, and crop growth, significantly enhancing agricultural efficiency [1]. - The use of drones to deploy "bee dispensers" containing over 5,000 parasitic wasps (Trichogramma) for biological pest control represents a shift from chemical pesticides to environmentally friendly solutions [2]. Group 2: Economic Impact - The smart agricultural system in Tieling is projected to generate an annual output value of 3.98 million yuan, which is a 33% increase compared to traditional farming methods [1]. - The promotion of drone technology for pest control in Shenyang aims to cover an area of 340,000 mu by 2025, indicating a significant expansion in the use of innovative agricultural practices [2]. Group 3: Irrigation and Power Management - The State Grid Shenyang Power Supply Company is enhancing irrigation efficiency by monitoring power supply for irrigation systems and creating personalized electricity usage plans for farmers [3].

Core Viewpoint - The article emphasizes the importance of a comprehensive green storage system for grain, which integrates intelligent monitoring, physical and biological control, and minimized use of chemical agents to prevent grain pests and ensure food quality [1][4]. Summary by Sections Green Storage Techniques - Green storage does not completely eliminate chemical agents but focuses on a "prevention first, integrated control" approach to form a collaborative ecological grain storage system [1][4]. - The annual loss of grain during storage in China exceeds 200 billion jin, with over half attributed to storage pests [1]. Low-Temperature and Low-Oxygen Environments - Creating low-temperature environments in grain storage can suppress pest activity and microbial growth, with temperatures below 15°C causing pests to enter dormancy or die [2]. - Technologies such as internal circulation temperature control and nitrogen gas storage are employed to maintain low temperatures and low oxygen levels, effectively killing pests without chemical residues [2]. Biological Control Methods - Establishing a micro-ecosystem in storage facilities can help control pests through biological means, such as introducing natural enemies like parasitic wasps and using targeted microbial agents [3]. - Despite challenges in large-scale application, biological control methods have shown promising results in specific ecological zones and may complement chemical methods in the future [3]. Digital Monitoring and Data Analysis - Transitioning from passive to active pest control involves utilizing advanced intelligent monitoring systems that integrate various data sources to predict pest outbreaks and trigger preventive measures [3]. - Technologies such as distributed traps and high-spectral cameras are used to collect real-time data on pest activity, enabling targeted interventions [3].
