Environmental acquisition of B. gladioli Lv-StA by L. villosa evaluated via qPCR. Abundances of Lv-StA in single glands of adult L. villosa females exposed as aposymbiotic larvae to the bacteria are shown. Detected gene copy numbers of Lv-StA 16S rRNA are significantly higher in individuals that were exposed to infected leaves (N=20) than in non-exposed control insects (N=12; Wilcoxon Rank Sum test, p<0.001). Titers in non-exposed beetles were on par with or below qPCR NCs, which include no-template samples (3x) and E. coli genomic DNA (1x). Dots within the violin plot represent individual samples and lines indicate the median.
