Abstract

The distribution of Rastrococcus spp. within mango trees (Mangifera indica) was studied at Bangalore, India. Population densities of R. invadens Williams, R. iceryoides (Green) and R. mangiferae (Green) were significantly higher on the abaxial leaf surface compared with the adaxial surface. Mealybug density was also higher from ground level up to 2 m compared with above 2 m. Significant variations in Rastrococcus spp. populations among trees and species composition per tree were observed. As populations built up on leaves, migration to other leaves occurred, more predominantly in R. mangiferae than in R. invadens. As the population of R. iceryoides increased on leaves, migration to twigs occurred.
