Dear colleagues, Several years ago we identified some candidate sex pheromone components of Gilpinia socia and G. frutetorum. However, we have not had the chance to verify the behavioural activities of the chemicals and we are now looking for places where these species may occur in reasonable densities. So, in case you have some useful information, please let me know.
