483 results about "Pheromone signaling" patented technology

However, sex pheromones are particularly associated with signaling mating behaviors or dominance. The odors released can be seen as a favorable trait selected by either the male or female leading to attraction and copulation. Chemical signaling is also used to find genetically different mates and thus avoid inbreeding.

Apparatus for Trapping Insects

A system and method are provided to control the amplification of natural frequencies emanating from molecules, specifically insect sex pheromones. The pheromone molecules are deposited in a resonant cavity that allows the generation of coherent and / or semi-coherent radiation. The molecular emissions are amplified in the resonant cavity and allowed to escape through a small circular opening on top of the resonant cavity. The molecules and / or their emissions dissipate into the surroundings to attract insects towards the cavity. When the insect enters the resonant cavity, a trap door prevents the insect from exiting. The molecular emissions are produced by passive diffusion and passive amplification because no pumping radiation source is required. However pumping radiation can be integrated to assist the passive amplification or serve as a second attractant.
