Summary
Microbiological and entomological findings made from the studies on the leaf-galls ofPongamia glabra Vent., are presented. Use of various routine and enrichment media resulted in the isolation ofPseudomonas æruginosa, Pseudomonas arvilla, Pseudomonas astragali, Pseudomonas Hydrophila andMicrococcus citreus. In the light of the revelations made, a brief discussion has been he d, and it has been suggested that the insects as well as the bacteria associated may symbiotically be the cause for the galls to form and that the insects by themselves may not be the sole factor responsible.
