华盛顿8月10日路透电 – 美国农业部周一在X平台的帖子中表示，德克萨斯州一座用于繁育无菌蝇以对抗螺旋蝇的设施将提前于2027年春季启用。
该机构此前曾表示，这座工厂将于明年年底投产。

今年6月，德克萨斯州发现了三十年来美国首例寄生性新大陆螺旋蝇虫害，该虫害可能给该州畜牧业带来高达10亿美元的损失。

对抗螺旋蝇的主要手段是投放无菌螺旋蝇，目前这类蝇类主要在巴拿马的一座工厂生产，该厂每周可产出1亿只蝇虫。
美国农业部新大陆螺旋蝇快速响应账号在X平台的帖子显示，这座规划中的德克萨斯州工厂将在2027年底前新增每周1亿只无菌蝇的产能。
该帖子称，到2028年底，该工厂的产能将达到每周最多3亿只。
专家表示，需要约5亿只无菌蝇才能将螺旋蝇向南驱赶至达连峡——巴拿马与哥伦比亚之间的热带雨林地带。

WASHINGTON, Aug 10 (Reuters) – The U.S. Department of Agriculture said in a post on X on Monday that a Texas facility to breed sterile flies to combat screwworm will open ahead of schedule in spring 2027.
Previously, the agency said the plant would open at the end of next year.

The first U.S. infestation of the parasitic New World screwworm fly in three decades was detected in Texas in June, threatening as much as $1 billion in losses to the state’s livestock industry.

The main tool used to combat screwworm is the dispersal of sterile screwworm flies, which are mostly produced in Panama at a plant that churns out 100 million flies per week.
The planned Texas plant would produce an additional 100 million sterile flies per week by the end of 2027, according to the post on X from the USDA’s New World Screwworm Rapid Response account.
That production would reach up to 300 million per week by the end of 2028, the post said.
Experts have said about 500 million sterile flies are needed to push screwworm southward to the Darien Gap, the stretch of rainforest between Panama and Colombia.
