Current Progress/Outcomes:
This achievement focuses on the green control of Spodoptera frugiperda, establishing a full-chain technical system centered on natural enemy insects, covering "resource exploration - industrialized production - field application". It has built China's first automated production line for dual wasp species, breaking through the bottleneck in the industrialization of natural enemy insects, and realizing large-scale production of Trichogramma chilonis (with an annual output of 1 billion individuals) and Telenomus remus (500 million individuals per year).
An innovative "composite wasp ball" technology has been developed, integrating the coordinated release of the two wasp species, which increases control efficiency by 30% and reduces costs by 40%. Adaptive technologies for the entire growth period of maize have also been developed: releasing adult Eocanthecona furcellata at the seedling stage (20 individuals per mu), and applying granular formulations while releasing wasp colonies at the trumpet stage, achieving a control efficiency of over 94%.
By integrating natural enemy insects, biopesticide, light trapping technology (insecticidal lamps with specific wavelengths), and sex pheromones, a three-in-one control system of "attraction - repellence - control" has been formed. This achievement is supported by the project "Research and Development of Core Technologies and Products for Biological, Physical and Chemical Attraction-Repellence Control of Spodoptera frugiperda" under the 14th Five-Year National Key R&D Program.
It assisted the Food and Agriculture Organization of the United Nations (FAO) in hosting the "Training Course on Sustainable Control of Spodoptera frugiperda in Africa" in Guangdong, where it concentratedly showcased the technological products and field effects of this achievement to African countries. Demonstration and promotion have also been carried out in African countries such as Kenya and Ghana, providing a systematic solution for the green control of major agricultural pests in Africa.
