Phlebotomus chinensis were fed respectively on two groups of Cricetulus barabensis infected with Leishmania donovani, of which one group had received deltamethrin bath and the other was not treated with insecticide bath. The results showed that all the sandflies in the former group died within 24 hours, while those in the latter group had a high survival rate. Among the 165 sandflies examined, 114 (69.1%) became infected. The promastigotes not only developed well in the midgut, but also invaded esophagus, pharynx and proboscis. In the control group, the mortality of sandflies in 24 hours was 5.1% (3/59). According to the data obtained in the present study, the authors consider that insecticide bath treatment of infected domestic dogs in endemic villages could be used for interrupting kala-azar transmission.
中华白蛉分别吸食两组感染杜氏利什曼原虫的黑线仓鼠,其中一组接受了溴氰菊酯药浴,另一组未进行杀虫剂药浴处理。结果显示,前一组的所有白蛉在24小时内死亡,而后一组白蛉的存活率很高。在检查的165只白蛉中,114只(69.1%)被感染。前鞭毛体不仅在中肠内发育良好,还侵入了食管、咽部和喙部。在对照组中,24小时内白蛉的死亡率为5.1%(3/59)。根据本研究获得的数据,作者认为,对流行区村庄中受感染的家犬进行杀虫剂药浴处理可用于阻断黑热病的传播。
