Experience the exotic: Explore leg-based olfactory sensations
In a groundbreaking discovery, a team of scientists led by Mohammad Belal Talukder and Carsten H. G. Müller from Greifswald University, in collaboration with researchers from Lund University, have identified the sensory organs responsible for smell detection in male spiders. The study, published in the prestigious journal Proceedings of the Royal Society B, sheds new light on the sensory biology of spiders and their mating behaviours.
The study found that the sensory organs for smell in male spiders are called sensilla basiconica. These organs are hidden beneath larger tactile bristles and hairs on their legs. Sensilla basiconica are located in the small pits beneath these tactile bristles and hairs and are sensitive to a wide range of chemicals, allowing male spiders to detect scent cues from females.
Male spiders use these scent cues emitted by the opposite sex to find mates. The discovery of the sensilla basiconica is significant in understanding the mating behavior of spiders. The study also found that the density of these sensory organs varies among different spider species, which may play a role in the mating success of male spiders.
This research could potentially lead to the development of new methods for controlling pest populations of spiders. By understanding how male spiders locate their mates, scientists can develop strategies to disrupt this process, potentially reducing the number of spiders in certain areas.
Previously, the sensory organs involved in this process were unknown. The study, therefore, provides new insights into the sensory biology of spiders and their mating behaviors. The study was focused on the sensory organs used by male spiders for smell and involved the use of microscopy to examine the sensory organs of male spiders from the genus Cupiennius and the species Aptostichus simus.
The study is the first to identify the specific sensory organs involved in the chemical communication between male and female spiders. This discovery applies to a large number of spider species, opening up opportunities for further research in this area. With this newfound knowledge, scientists can continue to explore the fascinating world of spider biology and behaviour.
