Fig. 2. Growth of valve apodeme during maturation is largely regulated by JH. (A)
Scanning electron micrographs of the valve apodeme of females from different
experimental groups. Apodemes of mature animals show increased length, width
and a more complex surface structure than those of immature and allatectomised
females (see also Fig. 1). By
contrast, apodemes from immature or precocene-treated females are rather flat
with a straight and smooth appearance. (B) Size-index values
(lengthxwidth) of apodemes from immature (<5 day), mature (>14
day), allatectomised (–CA) and those females injected with the JH analog
methoprene (–CA, +met). Apodemal size increases considerably between the
5th and the 14th day after adult emergence. Allatectomy markedly inhibits the
increase, but replacement injections with methoprene are able to significantly
reverse allatectomy effects. Data are means ± S.D.;
***P<0.001. Scale bar in A, 1 mm; anterior is to the
right.
