加州大学河滨分校研究人员发现了一种名为双三氟隆的化学物质，能够有效控制西方干木白蚁。1这种物质属于几丁质合成抑制剂，通过阻止昆虫制造足够的几丁质来形成新的外骨骼，利用白蚁必须蜕皮的生物特性将其生命周期中的正常阶段转变为致命弱点。1相比传统熏蒸方法，这种新型物质更加环保且对人类无害。1
在受控实验条件下，双三氟隆对西方干木白蚁产生了显著杀伤力。1仅有初次接触到该化学物质的白蚁占总群落的5%，但到第90天时，整个群落的死亡率达到100%。1当使用0.1%浓度的双三氟隆处理时，60天后产生了约99%的死亡率。1研究人员还发现，将松油烯与杀虫剂结合使用，可将死亡率从70%提高至95%以上。1
该研究成果已于2025年发表在《经济昆虫学杂志》上。1加州大学已于2025年4月提交相关专利申请，并于10月公开。1
Researchers at the University of California, Riverside have identified a chemical compound called bistrifluron that blocks western dry wood termites from forming new exoskeletons, killing over 95% of laboratory termite colonies.1 The substance exploits a critical biological vulnerability by converting the termite molting process—an essential stage of their natural life cycle—into a lethal weakness.1 Unlike traditional fumigation methods, bistrifluron offers a more environmentally sustainable approach with no harm to humans.1
The chemical functions as a chitin synthesis inhibitor, preventing insects from producing sufficient chitin for their new exoskeletons.1 In controlled experiments, bistrifluron achieved a 95.7% mortality rate with selective exposure and 99% under continuous exposure to the chemical.1 When only 5% of termites initially contacted bistrifluron, the entire colony reached 100% mortality by day 90.1 A 0.1% concentration of bistrifluron treatment produced approximately 99% mortality after 60 days.1 Researchers further enhanced effectiveness by combining the pesticide with pinene, increasing mortality rates from 70% to over 95%.1 The findings were published in 2025 in the Journal of Economic Entomology, with a patent application submitted by UC Riverside in April 2025 and made public in October of that year.1
