Abstract:
Leaf galls produced by psy I lids and mites cause considerable damage to the
Cinnamon crop in Sri Lanka. Trioza sp. (Homoplera, Psyllidae, Triozidac) and
mites of genus Eriophyes (Acarina, Lriophydae) are the most important gall
inducing organisms found in the Southern coastal area of the island. The
identification of the insect, the patterns of distribution of the two types of pests and
the structural differences of the two types of galls of the pests arc studied in this
project.
