浙江省某鼠传疾病监控点室内地面游离蚤杀灭方法研究

目的观察杀蚤剂复配对室内地面游离蚤的杀灭效果。方法采用25％速杀威乳油(主要成分为高效氯氰菊酯和残杀威)和连续二次施药方法。结果8个观察点中1、6、8号观察点蚤阳性指数分别由灭前的1．967、0．267和0．167下降至0．007、0．020和0．007，灭蚤率分别为99．64％、92．51％和95．81％；其他观察点阳性指数均降至0，灭蚤率均为100％，8个观察点平均灭蚤率为98．87％。结论采用复配方速杀型灭蚤剂和连续二次施药方法灭蚤效果显著，可在类似的地区和环境推广应用。

Study on Method of Killing Indoor Ground Free Flea in Mouse Transmission Diseases Monitoring Points in Zhejiang

Objective Study the indoor ground free flea control method to prevent occurrence and epidemic of mouse transmission diseases. Methods Using composite-formulated fast fleacide instead of the traditional method of applying a single fleacide, and successively spraying the fleacide twice, each 50 ml/m2 (ground not absorbing water) or 100 ml/m2 (ground absorbing water). Results In this study total 8 observation points were set up. After the application, the flea positive index (%) of #1, #6 and #8 observation point was reduced from previous 1.967 , 0.267 and 0.167 to 0.007 , 0.020 and 0.007 respectively and the flea-killed ratio(%) was 99.64 , 92.51 and 95.81 respectively. After the application, the flea positive index (%) of #2, #3, #4, #5 and #7 observation point was reduced from previous 0.153 , 0.133 , 0.740 , 0.120 and 0.187 to 0,and all flea-killed ratios (%) were 100. The mean flea-killed ratio(%) of 8 points is 98.98 . Conclusion Using composite-formulated fast fleacide and the applying method of successively twice spraying to consolidate the flea-killing effect gets satisfied results and this method should be popularized in similar areas and under similar environments.
