Lethal phenotypes caused by the RNAi for <i>SeTre-1</i> or <i>SeTre-2</i>.

<p>During the larva-pupa stage, the insects injected with dsRNA of <i>SeTre-1</i> produced three different lethal phenotypes, with a 63.6% proportion of the “severe-abnormal” phenotype (Bi-iii), while the insects injected with dsRNA of <i>SeTre-2</i> produced four different lethal phenotypes, with a 50% proportion of the “abdomen-abnormal” phenotype during the larva-pupa stage (Ci-iv). During the pupa-adult stage, the insects injected with dsRNA of <i>SeTre-1</i> produced two different lethal phenotypes, with a 66.7% proportion of the “misshapen-wings” phenotype (Biv-v), while the insects injected with dsRNA of <i>SeTre-2</i> produced three different lethal phenotypes, with a 68.6% proportion of the “half-eclosion” phenotype (Cv-vii). The pupae and adults in the ds<i>GFP-</i>injected control are shown in A.
