Irradiation of the infective larvae of Gaigeria pachyscelis Railliet and Henry, 1910 with gamma rays upto 160 Kr had no significant effect on the in vitro survival of these larvae for a period of 49 days, maintained either at room temperature (32.2--39.4 degrees C) or at 4 degrees C. However, the behaviour of the irradiated larvae in the lamb host was much changed, as shown by a marked reduction in the worm establishment and the development of stunted and sterile worms from these larvae. As the level of irradiation increased, there was a corresponding decrease in the subsequent worm establishment. It was found that male larvae are more sensitive to the effects of irradiation than female ones, particularly at higher levels.
用高达160千伦琴的伽马射线照射1910年拉耶尔和亨利所描述的粗颈盖胃虫（Gaigeria pachyscelis）的感染性幼虫，在室温（32.2 - 39.4摄氏度）或4摄氏度下保存49天，对这些幼虫的体外存活没有显著影响。然而，受照射幼虫在羔羊宿主体内的行为发生了很大变化，表现为虫体定植显著减少，且这些幼虫发育出发育不良和不育的虫体。随着照射水平的提高，随后的虫体定植相应减少。研究发现，雄性幼虫比雌性幼虫对辐射影响更敏感，尤其是在较高辐射水平下。
