Daniel FloresFebruary 3, 2010
CURRENT PRODUCTION
• during the months of October-November
• low-volume release of 20 parasitoids
• 2-3 generations
• parasitism rates of 19.8% were observed
• estimated 2000 parasitoids
• net return of 100X
Daniel FloresFebruary 3, 2010
PROJECTIONS
• increase our yield
• timing - in the spring and summer months
• release numbers - 10 to 50-fold
• inducing 2 to 5-times more flush
• project 40,000 - 200,000 parasitoids per tree
Daniel FloresFebruary 3, 2010
• Quarantine screening, rearing, and mass production of new strains of Tamarixia and any other biological control agents.
• Develop methods and protocols for the easy release of large volumes of biological control organisms.
• Qualify and quantify the impact of large-volume releases of biological control agents in organic groves, commercial groves, and dooryards.
• Transfer technology and/or biological control organisms to federal, state, and other cooperators in affected states for release.
