【目的】 为了开发一种高效环保型白蚁饵剂。【方法】 选定烯啶虫胺和溴虫腈对黑翅土白蚁Odontotermes formosanus进行室内毒力测定，根据室内毒力测定结果筛选毒力较高药剂进行驱避试验，并制备3种不同剂量的肠衣饵剂，开展室内白蚁毒杀效果试验和园林白蚁防治效果试验；选用合适剂量肠衣饵剂进行堤坝黑翅土白蚁诱杀试验，并用挖巢法检测肠衣饵剂对堤坝黑翅土白蚁的诱杀效果。【结果】   1.6 µg/mL烯啶虫胺处理黑翅土白蚁72 h后校正死亡率达100%，16 μg/mL溴虫腈处理72 h后黑翅土白蚁校正死亡率也达到100 %。室内毒力测定结果表明烯啶虫胺对黑翅土白蚁的LC₅₀值低于溴虫腈，100 μg/mL烯啶虫胺处理8 h后对黑翅土白蚁无显著驱避作用。3种剂量烯啶虫胺肠衣饵剂处理72 h后，黑翅土白蚁校正死亡率均在60%以上。将不同剂量的烯啶虫胺肠衣饵剂投放到园林中45 d后，肠衣饵剂基本被食空，施药点周围无白蚁及活动迹象。在福建省水库大坝周围投放60 μg/g烯啶虫胺肠衣饵剂，3个月后肠衣饵剂未发霉且基本被食空，6个月后挖巢发现蚁道内无黑翅土白蚁活动，白蚁巢体出现死亡和坍塌情况。  【结论】 60 μg/g烯啶虫胺肠衣饵剂对园林和堤坝中的黑翅土白蚁具有良好的诱杀效果，是一种高效环保型白蚁肠衣饵剂。

[Objectives]  To develop an efficient and environmental-friendly bait against termites. [Methods]  The toxicity of nitenpyram and chlorfenapyr baits to the termite Odontotermes formosanus was evaluated under laboratory conditions. Higher toxicity insecticides were chosen to determine their repellent effect on O. formosanus. Casing baits with three different pesticide doses were made in order to test both indoor toxicity and the effectiveness of control in the field. A suitable dose was chosen to carry out trials on the effectiveness of controlling O. formosanus in dams, which was subsequently tested by excavating termite nests. [Results]  The corrected mortality of O. formosanus reached 100% 72 h after treatment with 1.6 μg/mL nitenpyram and 16 μg/mL chlorfenapyr. The results of indoor toxicity test showed that the LC₅₀ of nitenpyram was lower than that of chlorfenapyr. Baits containing 100 μg/mL nitenpyram had no repellent effect on O. formosanus 8 h after treatment. The three different doses of nitenpyram casing baits all achieved a corrected mortality of 60% 72 h after treatment. Casing baits containing the three different doses were completely consumed by O. formosanus and there were no termites or signs of termite activity 45 days after baits had been deployed. Casing baits with 60 μg/g nitenpyram placed around dams in Fujian Province did not become moldy and were completely consumed by O. formosanus within three months. Moreover, there were no termites in tunnels and termite nests were either dead, or collapsed, six months after treatment. [Conclusion]  Casing baits containing 60 μg/g nitenpyram are an effective and environmentally-friendly method of controlling O. formosanus, both in the general landscape and in dams.
