“…Similarly, teneral male D. jeffreyi HMGR mRNA levels are not induced by JH III to the same extent as those in fully mature insects (Barkawi, 2002), suggesting developmental regulation. An antennally-mediated negative-feedback regulation in I. pini suggests possible neural influences (Ginzel et al, 2007) similar to that observed in L. decemliniata (Dickens et al, 2002). Finally, mevalonate pathway genes show a pulse of mRNA induction in fed male I. pini, whereas unfed, JH III-treated males show a steady increase in mRNA levels over time (Keeling et al, 2004.…”
