The benzoylurea chitin synthesis inhibitor diflubenzuron was evaluated as a rodent feed-through for the control of immature stages of Phlebotomus papatasi Scopoli (Diptera: Psychodidae). The development and survival of second instars of P. papatasi larvae that were fed feces from Syrian hamsters, Mesocricetus auratus, that had been fed a diet containing 0, 8.97, 89.7, or 897 ppm diflubenzuron was evaluated. No pupation or adult emergence occurred when larvae were fed feces from hamsters that were fed diets containing diflubenzuron. The mortality of sand flies fed feces from treated hamsters was coincident with pupation of the controls, suggesting a specific effect on the larval-to-pupal molt. The results of this study suggest that a control strategy using rodent baits containing diflubenzuron for phlebotomine sand flies and zoonotic cutaneous leishmaniasis may be possible.
苯甲酰脲几丁质合成抑制剂二氟苯脲被评估作为一种经鼠给药的方法，用于控制巴氏白蛉（双翅目：毛蠓科）的未成熟阶段。对取食来自喂食含0、8.97、89.7或897 ppm二氟苯脲日粮的叙利亚仓鼠（金仓鼠）粪便的巴氏白蛉幼虫二龄期的发育和存活情况进行了评估。当幼虫取食来自喂食含二氟苯脲日粮仓鼠的粪便时，未出现化蛹或成虫羽化。取食经处理仓鼠粪便的白蛉死亡率与对照组化蛹时间一致，表明对幼虫到蛹的蜕皮有特定影响。本研究结果表明，使用含二氟苯脲的鼠饵控制白蛉和人畜共患皮肤利什曼病的控制策略可能是可行的。
