Abstract: In this process of gall formation, cell proliferation, differentiation and hypertrophy occur which convert the inner-gall chamber. The results of present study revealed that, the galls of Trioza jambolanae on the leaves of Syzygium jambos generally occur as isolated epiphyllous pustules, with usually one and rarely two nymphal chambers. On the adaxial side of the leaf, they are expressed as linear swellings with a narrow slit-like ostiole, while along the abaxial side gall appears like spiral venation. The insect completes its life cycle in 40-42 days. Morphometric evaluation showed that in the process of life cycle insect stage converted from spherical egg to long Nymph and finally in winged male and female adults.
