  1. Biological Control RESEARCH SUPPORTED BY:

  2. Successful! • Silverleaf Whitefly • Giant Whitefly • Citrus Blackfly • Schefflera Whitefly • Ash Whitefly • More than 64 species in Florida.

  3. Driving Forces for Adopting Alternatives?

  4. 100% Reliance on Pesticides = RESISTANCE

  6. Biological Control Concepts “Biological control is the use of parasitoid, predator, pathogen, antagonist, or competitor populations to suppress a pest population, making the pest less abundant and less damaging than it would be in the absence of the biocontrol agent.” Definition:

  7. Biological control does not cause immediate reduction in target pest populations. It can take months to years. The Concept:

  8. Biological control may only achieve partial suppression of the target pest, as a residual pest population is necessary to maintain natural enemies. The Concept:

  9. In this particular situation, it will take cooperation of and creative thinking. The Concept:

  19. Widespread infestations impact what an individual might do.Some people will leave plants untreated so they will constantly impact what their neighbors are trying to do. The Issues:

  20. Bio-control AgentsNO Magic Bullet The Issues: What natural enemies are available? NOTHING COMMERIALLY!

  21. Bio-control AgentsNO Magic Bullet The Issues: What natural enemies are available? There are a number of naturally occurring predators and parasites.

  22. Bio-control AgentsNO Magic Bullet The Issues: We won’t have enough of them to go around. There is no infrastructure to produce them in the quantities we will need for the entire state. There are many whitefly species and each one will need its own complement of bio-control agents.

  23. Thank you!
