Thesis title: Sexual attraction and mating compatibility between FCM populations and the potential impact on sterile insect technique

Supervisors: Prof Martin Hill, Dr Sean Moore & Dr Candice Coombes

Sterile insect technique (SIT) has been developed as a form of control against False codling moth (FCM). Sterilized males from Citrusdal are released into the wild and mate with females to reduce the next generation. Recent research has however found that FCM appear to have geographically distinct sex pheromones. Therefore, the males are less successful at locating females from different populations. It is important to answer this question as SIT can be a costly control and differing sex pheromones may hinder the use of SIT at other locations across the country. If regional attractiveness of wild females to sterile males is found to be an issue, a FCM laboratory culture of mixed origin will be developed in an attempt to overcome these differences and improve the efficacy of SIT in all regions of the country.
