Abstract

Pauropsylla depressa Crawford (Homoptera: Psyllidae) infests Ficus glomerata Roxburgi and produces galls on its leaves, causing extensive damage to the foliage of the plant, (Mani, 1973). Galls are abnormal growth not only foreign organism, but also mechanical irritation, wounds and certain chemicals like mutagenic agents, various amino acids and excessive IAA and other plant growth harmones commonly induce the formation of gall. The gall formation by Pauropsylla depressa causing the changes in the histomorphology, ecology and biochemical components of the host plant. The galls are Green and pubescent at the beginning of bud expansion, but mature rapidly and soon after the emergence of the insects become dry, and turned brown. Hence, changes occur in FAA. The data clearly depict those healthy leaves process nine amino acids against clearly depict against 12 presents in galls.

In this way in healthy leaves only Alanine, Cystine, Glutamate, Glycine, Histidine, Lysine, Methionine, Phenylalanine, Proline, Threonine, Tryptophan was present. The gall tissues also exhibited a market increase in the quantities of Cystine Lysine, Phenylalanine as compared to those of healthy tissues, in case of F. glomerata gall, the quantitative changes in amino acids spectrum in both healthy and infected leaves as shown in the result clearly indicated that healthy least process 9 amino acids as against 12 presents in galls. The additional ones are Alanine, Threonine and Tyrosine. According to results, gall tissues also exhibited a marked increase in the quantities of Cystine, Lysine and phenylalanine as compared to those of healthy tissues.
