Histopathological observations on testes of adult blister beetle, Mylabris indica (thunberg) (Coleoptera: Meloidae) treated with neem

studies on the effects of neem on the histopathology of the testes of Mylabris indica revealed histopathological changes in the testes such as vacuolation, shrinkage of testis cyst cells, clumped and fragmented chromatin materials, disintegration and degeneration of germ cells such as spermatogonia, spermatocytes, spermatids and spermatozoa. The spermatocytes and spermatids became pycnotic and sperm bundles were disorganized, hypertrophied spermatozoa were also observed.
