It sounds like a sap sucking insect is sucking all the sap out of the branch before it can get to the leaves. It there is a white powdery substance it is likely you have mealybug. This little sap sucker produces the white powdery substance as well as honey dew which ants will collect, the ants will even spread them around the plant and protect them from natural predators.
