Seven species of scale insect and mealybugs belong to four families and three parasitoids belong to two families were recorded. Seasonal abundance, number of generations, effects of climatic factors, preferable surface and distribution for both of Hemiberlesia lataniae, Pulvinaria psidii and its associated parasitoids were studied.
