【“虫虫特工队”上岗！不用农药，守护满园青绿】
Beijing parks, including the National Botanical Garden, are using “insect task forces” instead of pesticides to control pests naturally. By releasing beneficial insects such as ladybugs, the parks rely on ecological balance to protect greenery, with more than 200 million helpful insects released each year.

近日，国家植物园等京城公园组建“虫虫特工队”，采用以虫治虫的生态模式防控虫害，全程不喷洒化学药剂。园区投放异色瓢虫等本土天敌昆虫，针对性捕食各类园林害虫。植物园依托生态规律保护繁育天敌，年均释放十余种、共计2亿只益虫，以自然制衡方式守护园林植被，助力城市生态园林稳步建设。
