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 article highlights the significant contributions of Zhou Yao to the field of entomology in China, emphasizing his efforts to establish a national identity in insect classification and biological pest control methods, ultimately aiming to reverse the historical narrative that has marginalized Chinese contributions in this field [1][5]. Group 1: Zhou Yao's Background and Education - Zhou Yao was a prominent entomologist who studied at the University of Naples under a leading authority in insect classification, becoming the only Eastern student in his program [3]. - He returned to China in 1938 amidst the outbreak of war, prioritizing national service over further studies, and later chose to work at the Northwest Agricultural College to contribute to agriculture and education [3]. Group 2: Innovations in Pest Control - In the 1940s, Zhou Yao developed a biological pest control method using parasitic wasps to combat wheat pests, which proved effective and saved millions of acres of wheat fields [4]. - He founded China's first national entomological society and a private insect research institute during wartime, demonstrating leadership in the field [4]. Group 3: Contributions to Chinese Entomology - Zhou Yao worked to establish a historical narrative for Chinese entomology, uncovering significant achievements in pest management from ancient texts, leading to the publication of a groundbreaking work in 1957 [5]. - He played a crucial role in founding the journal "Insect Systematics and Evolution," which connected China with the global scientific community [5]. Group 4: Legacy and Impact - Zhou Yao's lifelong dedication resulted in the collection of over 400,000 insect specimens and the discovery of 372 new species, significantly enhancing China's entomological resources [6]. - His contributions have established a foundation for ongoing research in biodiversity, with his museum housing 1.5 million specimens, marking it as a key institution in global biological diversity studies [6].

Group 1: Wheat Production in Saline-Alkali Land - Large-scale mechanized harvesting of wheat in China is nearing completion, with high yields reported in saline-alkali test fields in Shandong Binzhou, where new wheat varieties achieved over 600 kg per mu [1][3] - The local agricultural authorities have developed over 600 wheat strains to enhance the variety of wheat resources suitable for saline-alkali land [3] - The focus is on transforming saline-alkali land into a new high ground for agricultural efficiency and farmer income through effective technology transfer [5] Group 2: Corn Planting and Quality Improvement - In Handan, Hebei, corn planting has commenced following the summer grain harvest, with measures like seed-fertilizer co-application being promoted to improve planting quality [7][11] - The seed-fertilizer co-application technique allows for simultaneous sowing and fertilization, optimizing fertilizer usage and enhancing seed growth [9][13] - As of now, Hebei has completed corn planting on over 30 million mu, achieving 85.3% of the total planned area [11] Group 3: Pest Control Innovations - In Tieling, Liaoning, the use of drones to release egg masses of Trichogramma wasps is being implemented as a biological pest control method to manage rice pests [15][16] - This method is particularly effective during the egg-laying period of the rice borer, with drone application offering advantages in time efficiency, labor cost reduction, and operational convenience compared to traditional methods [18]

Group 1: Industry Overview - The first batch of goji berries in Ningxia has matured, with large-scale harvesting officially starting, and the expected fresh fruit yield for this year is 300,000 kilograms from a 1,500-acre farm [1] - The goji berry industry in Ningxia has a comprehensive output value exceeding 12.6 billion yuan, with over 120 types of processed goji products available [9] Group 2: Pest Control Innovations - Ningxia has established its first biological pest control base, utilizing aphid wasps to combat aphid infestations in goji berry farms, which helps reduce chemical pesticide use and enhances ecological safety [2][4] - The aphid wasp can control over 100 aphids, promoting a "bug control by bug" method that improves the quality and safety of goji berries from the source [4] Group 3: Water and Fertilizer Management - The implementation of integrated water and fertilizer management technology addresses issues of water waste and low fertilizer efficiency, allowing for precise irrigation and fertilization based on the growth stage of goji berries [5] Group 4: Fresh Goji Berry Distribution - Fresh goji berries are packaged and transported using cold chain logistics, ensuring delivery to consumers within 24 to 48 hours after harvesting, enhancing the freshness experience [7]
