Impact of  ionizing  radiation  of X-ray  at  1500 r ( roentgen ) has  been  studied  on  the  spermatogenesis of Aulacophora foveicollis. X –ray  induced  chromosomal  aberrations  such as fragmentation, clumping,swelling,stickiness etc. in  the spermatogonial, primary  spermatocyte and secondary  spermatocyte  cells in their various stages. The size of cell and nucleus increases and their membrane are generally distorted. The changes in their nucleolar persistence, nucleolar vacuole and perinucleolar ring has also been observed. The effect of X-ray radiation on the further elongating spermatids contain vacuoles which later on fuse together and form an unstained tube like structure. This tube is also lost due to the elongation and condensation of the sperm nucleus. It causes mutagenic effect and create genetic imbalance.
