Dimorphic Stress Hormones Figure 2. Corazonin neuronal manipulations differentially impact survival during different forms of stress. Median survival times for different genotypes subjected to three different physiological stresses. Three replicate vials of thirty individuals were assessed twice daily for survival and non-linear regression was used to estimate median survival per replicate (GraphPad Prism, San Diego). Data are mean +/2 SEM from three replicates per genotype. Boxed asterisks indicate statistical difference between the background control (w1118) line (Blue bars) (ANOVA, p,0.05). doi:10.1371/journal.pone.0009141.g002 PLoS ONE | www.plosone.org 5 February 2010 | Volume 5 | Issue 2 | e9141
