Objectives
• Determine the complex behaviors of
Trigona biroi
• Determine a near-optimal way of training
the bees to learn a new food-type
• Determine the behavioral patterns of
Trigona biroi during
– Scouting
– Recruitment
– Foraging

Complex Systems
• Complex systems are composed of
interacting components that show dynamic
behaviors. Usually, such systems have
sophisticated structures, which make their
designs hard to comprehend.
• However, even though complex systems
are complex, they still work-out for
stability, and recognizable behavioral
patterns may exist (attractor and edge-of-
chaos).

COMPLEXITY OF
BEE COLONIES
There are many factors to consider in training the
bees:
• The food itself (e.g. sucrose concentration)
• Sunlight / light
• Direction of sunlight
• Open space
• Food location
• Weather
• Etc…
