Expression of 31 serine protease transcripts in eight different tissues including foregut (FG), hindgut (HG), midgut (MG), haemolymph (HL), Malpighian tubules (MT), carcass (CA), fat bodies (FB) and silk gland (SG) from <i>O. nubilalis</i> larvae.

<p>The expression levels of <i>OnTry13</i>, <i>OnCTP15</i> and <i>OnCTP11</i> were too low to be detected by RT-PCR. <i>O. nubilalis</i> ribosomal protein S3 (<i>OnRps3</i>) was used as a reference gene.
