A new study reveals how domesticated silkworm moths use wing flapping to manipulate airflow, boosting their ability to detect distant pheromones. This discovery sheds light on how moths guide pheromones to their antennae and opens up possibilities for designing advanced robotic systems capable of odor source localization.
Researchers explore how the domesticated flightless silkworm moth , a prominent insect model in olfactory research, uses wing flapping to manipulate airflow, enhancing their ability to detect distant pheromones. These findings highlight how moths guide pheromones to their odor sensors in antennae, and suggest potential applications for designing advanced robotic systems for odor source localization .
One of the key findings of the study was that B. mori samples the pheromone selectively from the front. The moth scans the space by rotating its body while fanning to locate the pheromone sources. The directional sampling of the pheromone molecules is particularly helpful when searching for an odor source since the moth can determine the direction of the odor plume upon the detection of the pheromone.
Furthermore, the study highlights the need for future research to consider environmental factors such as airflow turbulence and antenna structure, which also influence odor detection."Currently, robots rely heavily on vision and auditory sensors for navigation. However, as demonstrated by disaster rescue dogs, utilizing the sense of smell can be highly effective for locating humans.
Graphene-based olfactory sensors that can detect odor molecules based on the design of peptide sequences were recently demonstrated. The findings indicated that graphene field-effect transistors ...
