During 2004-2005 our research focused on several areas. The first was testing a new gel- based diet developed to take the place of the agar sugar block diet used to feed adult Tephritid flies prior to sterile insect technique (SIT) releases. Unfortunately, the gel formulation was deficient in protein which resulted in production of adults that were not efficient in producing pheromone or attracting females (Figures 1, 2). Formulation of the gel diet with additional protein, needed to improve reproductive competence, yielded an inconsistent formulation. Additionally, the gel diet was expensive and labor intensive to formulate. As such the gel diet was judged a poor substitute for the agar/sugar blocks.
