Resumen:
In eusocial insect colonies, as honeybees, many tens of thousands of workers can livetogether as a regulated superorganism. These colonies are characterized by division oflabour: specialization of individual workers for particular tasks. Honeybees have developedcollective food acquisition methods to provide themselves with nutrients. They split the foodgathering task into a variety of subtasks performed by different individuals. Foragers searchfor food sources, collect food, and transport it to the nest, where it is processed and storedby other groups of workers. The aim of this work was to develop a software, called BeEp,which asserts a causal relationship between honeybee’s age, task performance, populationand food balance. We describe a novel multi-agent model (MAMS) that focuses on thedynamic task selection of honeybees. The behavior of the complete system was directlyreproduced by simulating the actions of the individuals. Our simulation was intended to modelall the important aspects of a bee’s life inside the hive. We assume differentiation amongcastes (workers, drones, queen). Queen is the only one who is in charge to deposit their eggsin empty cells. Workers bees are physiologically and morphologically identical; we emphasizethe differentiation among these according to age and therefore their activity in the colony.This includes individual development from egg to adult and adult performing tasks such asbrood tending (nursering), storage nectar-pollen (storing), as well as, collection of nectarpolen(foraging). The software also considers transformation of the nectar in honey. Adultbees of all ages satisfy their energy demands by consuming stored nectar (honey) or by beingfed by other adults. The larvae (brood) must be fed by nurse’s bees. We have simulatedhoneybee’s colony of 2000 individuals in 4 frames for the term of 365 days, maintainingnutrition and population balance. The software consists of multiple parallel programs that runsynchronized: GoReporter, details the statistics of the simulation, BeTV allows following thesimulation in one computer that runs on another computer with better operationalcharacteristics. BeEp also generates an event monitor, which shows step by step theprogress of the simulation. The software works on a colony simulation performed by multiplecomputers in parallel (clusters), this reduces dramatically simulation times. In parallel wemade experiments with real honeybees in mini colonies to validate the simulation. We plan toutilize our model for additional studies such us: beekeeping epidemics, pollination and honeyproduction.
