Observations on the witches-broom formations in Scurrula pulverulenta (Wall.) G. Don (Loranthaceae)


, : Observations on the witches-broom formations in Scurrula pulverulenta (Wall.) G. Don (Loranthaceae). World Weeds 2(2): 63-68

Observations on witches broom formations which were found on up to 10-20% of Scurrula pulverulenta during a survey in Doon Valley (Uttar Pradesh) are presented. The growth pattern of S. pulverulenta is described. The hyperparasite causing witches brooms is identified as an insect, Sumatraphis n. sp., which feeds on hosts of all ages and stimulates vegetative and reproductive structures to develop into witches brooms.
