Although most insect colonies are headed by a singly mated queen, some ant, wasp and
bee taxa have evolved high levels of multiple mating or 'polyandry'. We argue here that a …

The integration of evolutionary biology with developmental genetics into the hybrid field of
'evo-devo'resulted in major advances in understanding multicellular development and …

One hundred years after Darwin considered how sexual selection shapes the behavioral
and morphological characteristics of males for acquiring mates, Parker realized that sexual …

We determined whether there is an association between nutritional state (as indicated by
stored abdominal lipid amounts) and division of labour in the honeybee, Apis mellifera. We …

Personality differences (ie consistent between-individual differences in behaviour) play an
important role in the lives of humans and other animals, influencing both their day-to-day …

Understanding how genotypic variation results in phenotypic variation is especially difficult
for collective behaviour because group phenotypes arise from complex interactions among …

Primer pheromones are thought to act in a variety of vertebrates and invertebrates but only a
few have been chemically identified. We report that a blend of ten fatty–acid esters found on …

Honeybees (Apis mellifera) are insects living in colonies with a complex social organization.
Their nest contains food stores in the form of honey and pollen, as well as the brood, the …

Publisher Summary This chapter discusses the endocrine control of insect polyphenism.
Polyphenism in insects is associated with some of the most striking and successful life …

Previous studies of the division of labor in colonies of eusocial Hymenoptera (wasps and
bees) have led to two hypotheses regarding the evolution of juvenile hormone (JH) …
