Mating behaviour of horehound plume moth: implications for Allee effects

Simulation models suggest that, in the absence of stochastic environmental effects, the successful maintenance or growth of a population from intentional releases depends on four main factors: release numbers, mate finding distance, reproductive rate in the field and dispersal (Hopper and Roush 1993). This project was undertaken as a part of a larger effort aimed at facilitating efficient release of the horehound plume moth, Wheeleria spilodactylus (Curtis), for biological control of the noxious weed horehound, Marrubium vulgare L.. Two Ph.D. students at the University of Adelaide, Craig Clarke and Jeanine Baker, are currently collecting data on plume moth establishment, spread and population growth. However, the mate detection distance of the horehound plume moth was previously unknown.
