Wild-caught Phlebotomus ariasi Tonnoir, starved until their sugar meals had been digested, were caged for 24 h with plants or plants infested with aphids and then tested for fructose, a constituent of plant sap. No evidence was found that the flies took sap directly from nine types of plants present in their habitat. About two-thirds of flies caged with oak (Quercus ilex L.) infested with an aphid [Lachnus roboris (L.)] and about a fifth kept with leaves of the french bean (Phaseolus vulgaris L.) infested with an aphid took honeydew. Experiments with three other aphid species gave negative results. Of sandflies caught in an oak tree infested with aphids, half of the females and three-quarters of the males contained fructose. Tests on females caught in a house and grouped according to state of engorgement showed that, having taken blood, the females stop taking sugar until the bloodmeal is completely digested. It is predicted that honeydews are important in the development of Leishmania infantum Nicolle in the gut of P. ariasi.
捕获的野生阿氏白蛉（Phlebotomus ariasi Tonnoir），饥饿至其糖餐消化完毕后，与植物或被蚜虫侵害的植物关在一起24小时，然后检测植物汁液的成分果糖。未发现有证据表明这些白蛉直接从其栖息地存在的九种植物中吸取汁液。约三分之二与感染蚜虫[栎长足大蚜（Lachnus roboris (L.)）]的橡树（Quercus ilex L.）关在一起的白蛉，以及约五分之一与感染蚜虫的菜豆（Phaseolus vulgaris L.）叶片关在一起的白蛉吸食了蜜露。对其他三种蚜虫进行的实验结果为阴性。在一棵感染蚜虫的橡树上捕获的白蛉中，一半的雌虫和四分之三的雄虫体内含有果糖。对在室内捕获并根据饱食状态分组的雌虫进行的检测表明，雌虫吸食血液后，在血餐完全消化之前会停止摄取糖分。据预测，蜜露在婴儿利什曼原虫（Leishmania infantum Nicolle）在阿氏白蛉肠道内的发育过程中很重要。
