Abstract
Tepa and metepa were administered in the food of adult female house flies, Musca domestica L., at 1.0% concentration. Ovarian development was inhibited in some flies between the 24th and 48th hr. In other flies ovarian development was not inhibited and the oöcytesin the 1st egg chambers, though smaller than normal in flies treated with tepa, were able to develop normally. The inhibited oöcytes in the 1st egg chambers of the tepa- and treated ovaries began degenerating at 48 and 72 hr, respectively. The developed eggs of the tepa-treated ovaries began degenerating at 120 hr, whereas the developed eggs of the metepa-treated ovaries did not show any sign of degeneration. Degeneration of inhibited oöcytes and noninhibited eggs became progressively more severe. The cells of the 2d egg chambers were either normal or in a degenerative condition in correlation with the condition of the cells in the 1st egg chambers. The 3d egg chambers became visible in some ovarioles at 96 hr in the tepa- treated ovaries and at 120 hr in the metepa-treated ovaries. None of the ftlies survived beyond 192 hours.
