Quantities of stored sperm. Spermathecae of all queens were dissected and the number of stored sperm counted, as described in the Materials and Methods. There were no significant differences in the number of sperm found in the semen-inseminated (denoted as “semen” in the graph below) and naturally mated (“mated”) queens. No sperm was found in the virgin or saline-inseminated group. The number of queens in each group is shown in the bottom of the bar. Statistical analysis: 2-tailed t-test, P = 0.75.
