A new pheromone of the silkworm moth Bombyx mori
- 331 Downloads
The female silkmoth Bombyx mori L. emits a second pheromone component bombykal (E-10, Z-12-hexade-cadien-1-al) in addition to the well-known sexual attractant bombykol (E-10, Z-12-hexadecadien-1-ol). Bombykal stimulates its own specialized and highly sensitive olfactory cells of the male moth. Surprisingly, the aldehyde inhibits the release of the male's wing-fluttering response to bombykol.

- 15.As a starting point for the comparison of our test concentrations with those expected in the wild, a single female gland placed in our apparatus at an airstream velocity of 1 m/s releases about as much bombykol as our standard filter-paper source carrying 0.1 μg bombykol. These considerations underline the importance of studies of related wild speciesGoogle Scholar
- 16.Bombykal is very unlikely to have been one of the three gaschromatograph fractions found to elicit behavioral responses by Anders, F., Bayer, E.: Biol. Zentralbl. 78, 584 (1959). One reason is that the bombykal concentration would probably not have been sufficient for an excitatory effect under their experimental conditions. In addition, bombykal can be excluded on the basis of gaschromatograph retention times Google Scholar
