Juvenile hormone regulatory pathways. A Biosynthetic and degradation pathways for juvenile hormone (JH) in BCW genome. Enzymes are marked in blue. AACT, acetoacetyl-CoA thiolase; HMGS, HMG-CoA synthase; HMGR, HMG-CoA reductase; MevK, mevalonate kinase; MevPK, phosphomevalonate kinase; MevPPD, diphosphomevalonate decarboxylase; IPPI, IPP isomerase, FPPS, farnesyl PP synthase; FPP, farnesyl PP pyrophosphatase; FDD, farnesol dehydrogenase, JHAMT, O-methyltransferase; JHEH, JH epoxide hydrolase; JHDK, JH diol kinase. B Changes in expression of JH pathway genes in northward- and southward-migrating moths and in moths after tethered flights of different durations. **p < 0.01; ***p < 0.001
