目的 研究百杀净雾化剂对蚤、螨等鼠体表寄生物的杀灭效果。方法 以粉尘螨和印鼠客蚤为试验对象，使用超微粒雾化机向模拟现场投放百杀净雾化剂，进一步使用硫酰氟和百杀净雾化剂对投放于集装箱内的蚤、螨进行杀灭，比较杀灭效果。结果 在百杀净雾化剂模拟现场试验中，印鼠客蚤（24 h）和粉尘螨（48 h）的死亡率均为100%；在容积为33.28 m³（长×宽×高分别为5.90 m×2.35 m×2.40 m）和67.68 m³（长×宽×高分别为12.00 m×2.35 m×2.40 m）的集装箱现场药效试验中，百杀净组和硫酰氟组印鼠客蚤24 h死亡率均为100%，但在这两种集装箱中百杀净组粉尘螨48 h死亡率与硫酰氟组比较，差异均有统计学意义（χ²=842.418、690.344，P<0.001），硫酰氟组无明显杀螨效果。结论 百杀净雾化剂对蚤、螨等鼠体表寄生虫具有较好的杀灭效果，值得进一步研究及推广应用。

Objective To study the efficacy against fleas and mites on rodents with Baishajing-aerosol product. Methods Dermatophagoides farina and Xenopsylla cheopis were selected as test subjects, an ultrafine atomizer was used to spray Baishajing-aerosol agent into simulated site to evaluate the efficacy of this product against fleas and mites. Sulphuryl fluoride and Baishajing-aerosol agents were further sprayed into the container respectively to compare the killing effect against fleas and mites. Results Fleas (24 h) and mites (48 h) mortality caused by Baishajing-aerosol agents were 100% in simulated field. In 33.28 m³ (5.90 m×2.35 m×2.40 m) and 67.68 m³ (12.00 m×2.35 m×2.40 m) heavy container field sites, X. cheopis (24 h) mortality in Baishajing-aerosol agents and Sulphuryl fluoride groups were 100%, but there was significant difference in mortality of D. farina (48 h) in Baishajing-aerosol agents and sulphuryl fluoride groups (χ²=842.418, 690.344,P<0.001). Sulphuryl fluoride group had no obvious acaricidal effect. Conclusion Baishajing-aerosol agent has a remarkable control effects against fleas and mites, and it is worthy of further research and application.
