morphological and anatomical studies of the ovary galls of sesamum indicum l. induced by the gall midge, asphondylia sesami felt

the organization of gall on the ovary ofsesamum indicum l induced by the gall midge, asphondylia sesami felt, not only affects biochemical equilibrium of the host but also causes disturbed vegetative growth and reduced seed-setting. the toxicity created by the gall maker induces the re-orientation of vasculature cecidogenetic stimuli lead to excessive hypertrophy and hyperplasy forming the gall chambers. each gall chamber is lined by a layer of dense mass of cells called nutritive zone. vasculature is disturbed during gall formation. one to few larvae are present in a larval chamber. occurrence of insect galls in the ovary of this taxon is remarkable and it is a new record in the field of cecidology.
