On the evening of August 7th, the 12th World Games grandly opened in Chengdu, Sichuan Province, immersing the city in a vibrant atmosphere. Meanwhile, Zhu Hang from southern Sichuan successfully completed a mosquito control mission using EAVISION J150 drones, building an invisible health shield for the main venue.
Another collaboration: mosquito control for the World Games
Looking back at the days leading up to the opening ceremony of the Chengdu World Games, Zhu Hang's team was on standby every evening. This task was no ordinary one; due to the tight schedule of the opening ceremony preparations, the original four-day mosquito control period was compressed to two days.
For this seasoned team, bigger challenges simply mean a better chance to prove their capability.
"The 2023 Chengdu Universiade first used EAVISION drones for pest control, and the organizers were satisfied with the results. This year, on the eve of the World Games opening ceremony, the task fell to us again—the organizers contacted us directly, specifically requesting drones with the same effectiveness," Zhu Hang said confidently.
EAVISION achieves excellence: providing precise support for international competitions
At 8 p.m., as the city lights gradually illuminated, the J150 drone took off precisely on time. In the complex environment of the city center, it accurately avoided obstacles and maneuvered nimbly.
In the lead-up to the operation, Zhu Hang and his teammates raced against time to report flight routes; on the day of the operation, they quickly delineated the work area using satellite imagery, making thorough preparations for efficient nighttime operations.
They didn't finish their task until nearly midnight, after the peak mosquito activity period had passed.
Over two days and six hours of work, Zhu Hang completed the operation covering 813 mu (54.2 hectares). The EAVISION drone, relying on its fine droplet size and stable wind field, evenly distributed the insecticide to every corner of the lakeside and the surrounding area of the venues, precisely blocking the mosquito's transmission path and building an invisible safety barrier for the successful hosting of the World Games.
Official standard: EAVISION drones lead the industry in 10μm droplet size.
On July 30, the Chinese Center for Disease Control and Prevention issued a notice on the "Technical Guidelines for Mosquito Control Using Drones (2025 Edition)" which clearly specifies the spraying parameters for adult mosquito control by drones: the recommended droplet size is 10-70μm.
The 10-300μm droplet size of EAVISION drones perfectly matches this recommended parameter.
Since 2017, EAVISION has been exploring the development of its own nozzles.
The fourth-generation CCMS® Bimodal Mist Nozzle features a built-in three-layer shearing and grinding structure and a double-layer flow-guiding atomization, enabling the EAVISION drone to stably output 10μm droplet size, leading the industry and setting a new industry benchmark.
Deep connections: from pilots to partners
Three years ago, Zhu Hang was a logistics driver; now he's a core partner of EAVISION in the southern Sichuan region.
After obtaining his pilot's license in September 2022, he and his team purchased two EAVISION J100 drones at once, and this year they added three new J150 drones.
"Before, I drove a truck for transportation; now I manage thousands of acres of orchards with a remote control," he jokingly calls it an "upgrade from steering wheel to remote control."
As the business expands, his team is also constantly growing: from an initial professional drone spraying team, it has gradually developed into a full-chain service company covering drone sales and maintenance.
Today, the team's workload has reached 60,000 mu (approximately 4,000 hectares) this year, and Zhu Hang's personal workload has exceeded 10,000 mu (approximately 667 hectares). Everyone is going further and further down the road of smart agriculture.
As the fireworks of the World Games lit up the Chengdu night sky, Zhu Hang looked at the bustling scene of the competition venues on the screen, feeling a sense of accomplishment.
This disinfection mission, which safeguarded the World Games, is a microcosm of smart agricultural technology entering a wider range of scenarios—as drones fly from the fields to the urban stage, the glimmer of technology helping agriculture is converging into a torch of urban services.
