用中华白蛉分别饲吸两组染有杜氏利什曼原虫的背纹仓鼠（Ｃｒｉｃｅｔｕｌｕｓｂａｒａｂｅｎｓｉｓ），一组系经澳氰菊酯药浴后９－４５ｄ的仓鼠，另一组系未经药浴的仓鼠。实验结果表明饲吸药浴鼠的白岭在２４ｈ内全部中毒致死，饲吸未经药浴鼠的白蛉存活率很高。在剖检的吸血白蛉中，有６９．１％的白蛉，在其消化道内发现有前鞭毛体的感染，这些前鞭毛体不仅在白蛉消化道内发育良好，且随饲吸时间的推移，前鞭毛体侵入食道、咽和喙部。背纹仓鼠是杜氏利什曼原虫理想的保虫宿主，经药浴的仓鼠进行人工感染，已失去感染能力。
Two groups of Cricetulus barabensis with Leishmania donovani were respectively fed with Chinese white catfish, one group of hamsters 9-45 days after the bath of the medroxypyr drug and the other group without the bath Hamster. The experimental results show that Bailing, a bassinet, is lethally poisoned within 24 hours and has a high survival rate after feeding medicated bath rats. In the autopsy, 69.1% of the catfish were found to have the infection of promastigotes in their digestive tract. These promastigotes not only developed well in the catfish ’s digestive tract, but also developed with the passage of the feeding time Promastigotes invade the esophagus, pharynx and beak. Back hamster is an ideal insect host for Leishmania donovani, artificial infection by the medicated bath hamster has lost its ability to infect.
