Figure 3. Chemical analysis of synthetic pheromone components.
GC-MS traces obtained from bombykol (upper trace) and bombykal (lower trace) samples freshly prepared to challenge BmorOR1•BmorOrco-expressing oocytes. Arrow indicates trace amounts of bombykal (1.3%) in the bombykol sample, whereas a dotted arrow shows traces of bombykol (0.9%) in bombykal sample. The ratio of bombykol (retention time, 16.06 min) to bombykal (15.42 min) in the two samples was 1.015±0.02, n = 3.
