Abstract: 
The infestation of Florida red scale on Citrus is just next to the black Parlatoria in Taiwan. The population is usually decreased during. rainy season from June to September. It infests leaves, twigs and fruits. The severe infested leaves usually fall .down and the twigs die. Resin soda wash could not control this species even though it has been extensively used for control unamored scales and mealybugs until the latest ten years ago. Fortunately 1.3% summer oil emulsive alone or 1 % summer oil emulsive in combination with 0.05 % malathion and 0.05 % dimethoate alone were recommended for control it and Aphytis chryso mphali (Mercet) usually restranis a certain number of individuals.
