PHEROMONE ATTENUATION: SIGNAL PERCEPTION IN CHANGING ATMOSPHERIC LANDSCAPES
Grant number: DP200101615 | Funding period: 2020 - 2023
Insects use chemical signals, or pheromones, to communicate with conspecifics. To convey information, the pheromone molecules must pass through the atmosphere and physically interact with receptors, typically located on the antennae of the receiver. Pheromones, like other organic compounds, are degraded by ozone, UV light, and radicals. While we know that pheromone plumes attenuate through the dispersal of molecules, the additional impact of pheromone degradation has been ignored. Our project aims to highlight the significance of odour survival for insect chemical communication by examining how atmospheric conditions, including air pollution, affects signal integrity, antennal morphology and..View full description
