Knockdown of <b><i>drd</i></b><b> in the tracheae does not cause starvation.</b>

<p>Triglyceride (a,b) and glycogen (c,d) levels of male progeny from crossing <i>btl-Gal4/CyO</i> females with either <i>w;{GD15915}v51184 UAS-Dcr-2</i> (a,c) or <i>w;UAS-Dcr-2 {GD3367}v37404</i> (b,d) males. No significant effect of genotype was seen by 2-way ANOVA. n = 10 flies/point. Pairs of male flies of the same genotype from the cross above were also utilized for defecation assays during the second day post-eclosion. Defecation assays were also performed on <i>drd^lwf;UAS-drd btl-Gal4(II)/btl-Gal4(II)</i> (e). Asterices indicate significant difference by 1-way ANOVA and Bonferroni’s post-test. ns p>0.05; *p<0.05; ***p<0.001. n = 6 pairs of flies/condition. Error bars represent SEM.
