When the trunk of a loquat fruit tree was heavily attacked by Platypleura kaempferi adults, the trunk of the tree became wet owing to continued exudation of tree sap from a hole where cicada had inserted its stylet. This condition provided a good chance for the spreading of sooty mold and die-back disease of the tree. Heavily infested trees were also apt to be attacked by Xyleborus saxeseni (RATZEBURG) and Grapholitha molesta BUSCK. A spraying of carbaryl was effective in preventing these infestations.
