Hessian fly: New insights to develop a gall nutritive tissue
Devika Rani D, Suneeta Pedada and Ranvir Singh
Gall midges constitute an important group of insects.it is plant parasitic. The Hessian fly (HF; Mayetiola destructor), it is the gall midge, was the first insect to have a gene-for- gene interaction with its host plant i.e. wheat (Triticumaestivum spp.). The Hessian ﬂy will produce nutritive tissue probably acts as a sink tissue within the wheat seedling, and it will not produce any galls, beneﬁting the growth of larvae by importing photo assimilates. Breakdown of nutritive cells began soon after they were ﬁrst observed, indicated by a change in the shape and density of the cell nucleus, that the HF, and other gall midges, may be considered biotrophic, or hemibiotrophic, plant pathogens, and they demonstrate the potential that the wheat-HF interaction has in the study of insect-induced plant gall formation.
