Thousands Of Years Of Captive Breeding Has Impaired Olfactory Functions In Silkmoths

Max Planck Institute Domesticated silkmoths Bombyx mori have a much more limited perception of environmental odors compared to their wild relatives. The extremely sensitive olfactory detection of pheromones in males eager to mate, however, remains unaltered. A new study on silkmoths published in Proceedings of the Royal Society B, revealed that the insects’ ability to perceive environmental odors has been reduced after about 5000 years of domestication by humans. Scientists from the...

Pheromone preference, and the initiation of a complex programmed sexual behavior, is determined by the specificity of a single sex pheromone receptor protein expressed in a population of olfactory receptor neurons in the silkmoth (Bombyx mori). The study, which will be published on June 30th in the open-access journal PLoS Genetics, provides the first direct proof of the long-held belief that the control of sexual behavior in male moths originates in the chemical specificity of the pheromone...

Researchers in the Department of Entomology,  University of California, Davis, have discovered that the fruit fly has a native odorant receptor that detects the silkworm moth's sex pheromone, and that it's "amazingly more sensitive" than the moth's odorant receptor. Their work could open research doors for insect-inspired biosensors. The odor detector or OR is a means of chemical communication that helps insects find mates.  The olfactory link between silkworm moths (Bombyx mori)...

Why recognizing sex pheromone components of the silkworm moth at the scale of atoms and molecules impacts on eco-friendly agriculture New research announced today, Wednesday 30th September, by a team of leading scientists working with the UK's national Synchrotron, Diamond Light Source, could have a significant impact on the development and refinement of new eco-friendly pest control methods for worldwide agriculture. Published in the Journal of Molecular Biology, the study was carried out by...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
