This project is not a research project but mainly a service project. Introducing genetic variation in classical biological control projects is important for giving the parasitoids the optimal chance to be successful. We have maintained 17 lines originally collected in Pakistan , supplemented with several lines initiated from wasps collected in California. Each generation we mix individuals from all lines to create a population that is mass-reared for one generation before they are shipped to the the mass rearing (CDFA, FAR). We grow 10,000’s of curry leaf plants in our greenhouses, to rear ACP. The ACP infested curry leaf plants are used for Tamarixia rearing and for use of other projects at UCR and UCSD that require ACP individuals for studying other ways of controlling ACP.
