Biological Control Modified Banker Plants L S Osborne
Biological Control & Modified Banker Plants L. S. Osborne
Modified Banker Plants § § § Uses alternate hosts Uses confined hosts Potential to sell entire system May be specific to region Can move plants out if pesticides are needed
Modified Banker Plants § § Used to establish natural enemies Used to augment natural enemies Used to increase natural enemy numbers Used to evaluate quality of natural enemies
Modified Banker Plants § § § Used to evaluate quality of natural enemies Used to slow PESTICIDE RESISTANCE Can be integrated with pesticides if necessary TRAINING!

Biological Control WHY?
100% Reliance on Pesticides = RESISTANCE
Crisis!
Biological Controls Parasites Predators Pathogens
Natural enemies • Parasite Parasitoid • Hyperparasite • Pathogen or nematode • Predator
TYPICAL RELEASE METHODS
Seasonal Inoculative Introduce natural enemies EIL Begin Cycle Time (months) End Begin Cycle
Problems- Economics
Problems- Availability
Problems- Quality Control
Problems- Pesticide Interactions
Solution? Modified Banker Plants (Open Rearing Systems)
Isolation Area 1 Clean Host Plants
Isolation Area 2 Infested Host Plants
Isolation Area 3 Infest with Natural Enemies
