“…This order of sensitivity accords well with that recorded for marty other insects, e.g. B. mori [4], D. melanogaster [5], and S. gregaria and Stenobothrus viridulus [17]. Exceptions include Cochliomyia hominivorax [7] and Abraxas grossulariata [18] in which the young primary spermatocytes are particularly sensitive.…”

During the development of a sterile male control method for Dermestes frischii Kugelann, testis follicles exposed to an X-ray dose of 3.0 krad were investigated using light and electron microscopy.There was considerable variation in the radiation sensitivity of the various somatic and germ cells. The cyst wall cells seemed particularly resistant while the inner layer of the bilayered follicle sheath was destroyed. The general resistance and versatility of the outer sheath layer maintained the integrity of the follicles. The only outer sheath and apical cells observed to decay were those in close proximity to degenerating germ cells. In some follicles all primary spermatogonia were destroyed, in others their numbers were only depleted. The surviving cells all underwent mitotic delay for 7-14 days. Their subsequent offspring were frequently found to break down and sometimes were proliferated so that germarial polarity was lost. All secondary spermatogonia but only a few primary spermatocytes were destroyed. The decay of germ cells within the same cyst did not necessarily proceed synchronously.

“…Sometimes, the mitochondrial derivatives were disorganized, and could not extend parallel to the flagellar filaments in the tail region of the spermatids. Most of such abnormalities have also been reported by other workers (Mathur 1960, Tahmisian and Devine 1961, Cantacuzene and Seureau 1970. Two or sometimes more centriole adjuncts were observed to be attached to the nucleus in the treated spermatids.…”

“…The nuclear membrane of the advanced spermatid became crinkled and lost its smooth outlines. Mathur (1960) reported the crinkled membrane of the nucleus in male germ cells of Steno bothrus viridulus following x-ray irradiation. Saxena and Aditya (1969) reported pycnotic nuclei in some spermatocytes and spermatids, 15 to 24 days after treating Poekilocerus pictus with apholate.…”

“…Two or sometimes more centriole adjuncts were observed to be attached to the nucleus in the treated spermatids. Mathur (1960), in his report on the effect of radiation with light microscopy, described four centriolar bodies on the posterior half of the nuclear membrane of spermatids. Tahmisian and Devine (1961) reported that after irradiation the centrioles at spermatogonium and spermatocyte stages were divided at least twice, resulting in four centrioles in one spermatid.…”

“…Supernumerary centrioles and axonemes, quite normal in structure, have been observed in the spermatids of M. differentia/is [2), D. melanogaster [3) and S. gregaria [4). Several axonemes have also been observed in pseudospermatids, cells formed after the failure of one or both meiotic divisions, in Chorthippus longicornis [5), Locusta migratoria and Rhomaleum micropterum [6) and Stenobothrus viridulus [7].…”

During the development of a sterile male control method for Dermestes frischii Kugelann males were exposed to an X-ray dose of 3.0 krad. The treated testis follicles were investigated using light and electron microscopy.Abnormalities in spermatids and sperm were observed only in cells treated as primary or secondary spermatocytes. Malformed nuclei, nebenkern and acrosomes were detected. Cells frequently failed to start or complete the first or second meiotic divisions. However, spermiogenesis was not inhibited and this resulted in the formation of pseudospermatids of which three types were identified. Only one of these has been previously described. Pseudospermatids were associated with two, three or four sets of quite normal tail organelles. The presence of multiple organelles is discussed in relation to similar findings in other insects.
