Abstract

Leaf galls on Ficus ulmifolia Lam. caused by Pauropsylla deflexa Uichanco are commonly observed in various locations in Mt. Makiling. Samples of normal and galled leaves were collected for anatomical studies. Samples were fixed, embedded in paraffin, sectioned, and stained with safranin and fast green. Measurements were done on the different tissues of the galls for comparison with those of healthy or normal leaves. Leaf galls arise from modifications of the morphogenes of the cells and tissues of plant organs. Thick layers of parenchyma were observed on cross sections of leaf galls which are modified palisade mesophylls of normal leaves. Other modifications observed on the leaf gall are apparent adaptations to protect the insect contained inside its chamber.
