ABSTRACT
Ptyomaxia syntaractis Turner, causes regular defoliation on the mangroves of Mumbai region particularly in Airoli creek of Navi Mumbai areas of Maharashtra. This pest is prevalent during the post monsoon period and infesting Avicennia marina severely in Airoli mangroves. The assessment of intensity of infestation revealed 64 to 70% infestation from September to November. The biology of the pest is studied in the laboratory. Also natural occurrence of the bacterial pathogen Myroides odoratus is observed for the first time on P. syntaractis in field condition. The pathogen was identified carrying out the method Genomic DNA isolation, PCR amplification using universal 16s rDNA primers and DNA sequencing. Pathogenicity test confirmed the infectivity of the bacteria on P. syntaractis in laboratory condition.
Key words: Ptyomaxia syntaractis, Mangroves, Pathogen, Intensity, Assessment
