The influence of larval age and exposure duration on the effects that chlorpromazine has on metamorphosis in larvae of Crepiduhi fomicata. Excess K+ was used as a convenient and reliable method tm inducing metamorphosis, (a) Data for the first 6-8 h of exposure, (b) Data for the first 24 h of exposure. Larvae were obtained from a different female for each of the four experiments. Each bar represents the mean response (+ 1 SD) of larvae in 4 replicates, 10-12 larvae per replicate. "1" indicates a significant difference in the means of chlorpromazine and control outcomes (P < ); , that chlorpromazine stimulated metamorphosis significantly above control levels. "2" indicates a significant difference in the means of exce^ K+ and (chlorpromazine + excess K+) outcomes; that chlorpromazine significantly blocked the siinmlutory ef- fects of excess K+. ND = No Data. The numbers in parentheses below the .v-axis give the ULV- of the larvae when tested, in days. The dates of each assay, along with mean shell lengths of the larvae tested, are given in Table Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble th
