The average brood size plotted in the sequence of its production by pairs from the populations of Artcmia surviving the evaporation-reconstitution cycle of 1971 to 1972.

The broken line indicates that less than half of the pairs remain alive. 1972 pair mating tests Results are summarized in Table III for the jar populations that survived to provide shrimp for testing a year after treatment. Adults from treated popula- tions tended to die earlier than those from the control, but in 1972 the mean life span of controls was about a week shorter than in 1971. Accordingly, the dif- ferences between means are not large, and t tests reveal significant decreases only for males and females of the 1,5-D group. The first IMH generation of only 1 male and 3 females was inadequate for such analysis. A ranking of the average number of broods is concomitant with a ranking of female life spans. The t value for 1,5-D exceeds that for £ Even the t value.
