目的研究4种电热液体蚊香〔0.12%四氟甲醚菊酯(A),0.17%四氟甲醚菊酯(B),0.86%四氟苯菊酯(C),0.86%四氟丙炔菊酯(D)〕在野外对流行性乙型脑炎(乙脑)媒介的控制效果。方法采用人诱法,比较测定控制蚊虫前、后密度的下降率,调查蚊虫密度。结果试验主要蚊虫为传播乙脑的三带喙库蚊和致倦库蚊。蚊香样品中仅有样品A使三带喙库蚊的密度下降率>80%,样品B、C和D使三带喙库蚊密度下降率均<80%;蚊香样品A、C、D使致倦库蚊的密度下降率>80%,样品B使其密度下降率在70%～80%之间。结论4种蚊香样品在现场有良好的驱避致倦库蚊和三带喙库蚊的效果,但是蚊香B的驱蚊效果要差于蚊香样品A、C、D,野外试验结果与实验室药效有差别。
OBJECTIVE To study the effects of four kinds of mosquito coils (0.12% Tetramethrin (A), 0.17% Tetramethrin (B), 0.86% Transfluthrin (C) Ester (D)] in the wild on Japanese encephalitis (JE) vector. Methods The human induced method was used to compare and control the decline rate of the mosquito before and after the mosquito, and the mosquito density was investigated. Results The main mosquitoes in the test were Culex tritaeniorhynchus and Culex pipiens quinquefasciatus transmitting JE. In mosquito-repellent samples, only sample A reduced the density of Culex tritaeniorhynchus by more than 80%, and samples B, C and D reduced the density of Culex tritaeniorhynchus by 80% The density of Cx. Pipiens quinquefasciatus decreased more than 80%, while that of sample B decreased from 70% to 80%. Conclusion The four mosquito-repellent incense samples have a good repellent effect on Culex pipiens and Culex tritaeniorhynchus in the field, but mosquito repellent effect of mosquito coil B is worse than that of mosquito repellent samples A, C and D. The field test results and laboratory medicine Effective difference.
