Abstract

T. fletcheri forms pouch galls on the leaf of T. nudiflora which stunt the growth of the plant up to some extent. Three predators C. compressus, A. nemoralis, H. westwoodi; and one pathogen Aspergillus flavipus are recorded. One ectoparasite Polyblastus Sp. and one endo-parasite Tetrastichus Sp. are observed. Their predation and parasitism capabilities were analysed both in field and lab.
