ANALYSES OF THE DIFFERENTIAL RADIOSENSITIVITY OF DEVELOPING REPRODUCTIVE TISSUES IN HABROBRACON JUGLANDIS (ASHMEAD) TO IONIZING RADIATION
Significant developmental stages throughout the life cycle of the holometubolous and ectoparasitic insect, Habrobracon juglandis (Ashmead) were x rayed with 300 r increments until sterility was illustrated by adult performance. Because of parthenogenetic male production, attention was focused on females. Cytological examination of ovarioles from adults x rayed at the different stages gave rise to three conclusions concerning the radiopathology of the reproductive system. Regardless of dose, somatic tissues functioned normally to produce four ovariole sheaths. Radiation of larvae adversely affected the trophocytes rather than the oocyte itself, apparently the damage is chromosomal. Hadiation of pupae interfered with egg-nurse syncytia differentiation from oogonia. (auth)
