The Enseada neighborhood of Guarujá is a residential area with three to
five story appartment buildings between the beach promenade and the
main avenue (Avenida Dom Pedro I).
As shown in the map, the Dom Pedro I Avenue is a lively business area
where you can find banks, supermarkets and all kinds of small stores. Close
to the beach front are the main hotels, including Casa Grande, and many
bars and restaurants, as well as the Beach Shopping mall with all kinds of
small shops and lunch and snack booths. Also, don’t forget to visit the Gua-
rujá Aquarium close by.
The beach front promenade of about 6 km invites strolling or a work out.

                                         sterility in honey bees

                              Insect societies are characterised by reproductive
                              division of labour, whereby one or few females are
                              queens that monopolise reproduction, while all the
other females are subfertile or sterile workers. In terms of Evolutionary Biology
the two essential questions are: why should a female give up on reproduction,
reducing her individual fitness to practically zero, in favour of another female, and
second, what are the underlying mechanisms for worker sterility and how could
these have evolved? While kin selection theory provides an evolutionary genetics
framework for the Why question, the How question is only now, with the
advances in molecular genetics and genomics, becoming amenable to investigation,
especially in the honey bee, Apis mellifera, which was the third insect species to
have its genome fully sequenced and annotated. This allowed us to investigate the
genetics underlying mutant phenotypes, such as the “anarchistic bees” that we
found in colonies as evading and resisting the repression of reproduction and that
we could keep through a selection program for years to understand the molecular
basis of worker sterility. We could pinpoint a key gene in this mechanism, Anarchy.
The gene is overexpressed in workers, leading to their subfertile state. Another
process that is key to worker sterility is the regulation of programmed cell death
in the worker ovary. This process affects different aspects of the morphology and
function of the reproductive system throughout the entire life cycle of a honey
bee worker, starting with the larval stages when caste fate is determined until
the nurse to forager transition., shortly before the end of a worker’s lifespan. I
will review here the major advances that we made over the years to understand
the regulation and evolution of worker sterility in Apis mellifera, the main model
organism for social insect biology, and give an overview on open questions that we
will still need to address.

We see such behavioral ecology results as fundamental for understanding foraging            evolution of such a special bee as A. mellifera capensis, and it is the recent advances
decisions of honey bees in the context of agricultural crops.                               on these questions that will be addressed in my presentation.
