(A) Brain polyamine (putrescine, spermidine, and spermine) titres in control females (controls), allatectomized females (CA−), α-DFMO-treated females (DFMO), and α-DFMO-fed females supplemented with putrescine (DFMO + put.). Data are the mean values ± SEM. Sample size is indicated in the spermine columns. Columns with the same sign are not significantly different. (B) Brain polyamine (putrescine, spermidine, and spermine) titres in allatectomized females (CA−) submitted to various experimental treatments. Putrescine (put.) or α-DFMO (DFMO) were given in drinking water from emergence onwards. JH III (100 μg/10 μl paraffin oil) was injected at emergence into females, which were provided with α-DFMO (DFMO + JH) or not (JH). Data are the mean values ± SEM. Sample size is indicated in the spermine columns. Columns with the same sign are not significantly different.
