What is Conserved Role of Juvenile Hormone in Regulating Behavioural Maturation and Division of Labour in a Highly Eusocial Wasp about?

Juvenile hormone (JH) in insects plays a key role in regulating reproduction, but in some social insects it has also acquired secondary functions in regulating the age-related division of labour among the workers. Previous work has shown that JH regulates division of labour in honey bees, in several primitively eusocial paper wasps and in leafcutter ants, which comprise three independent origins of sociality. It remains unclear, however, to what degree JH could have a conserved role in regulating division of labour within these clades. To this end, we investigated whether JH also regulates division of labour in the highly eusocial Vespine wasp Vespula vulgaris, in which JH had previously been shown only to regulate reproduction and affect queen pheromone signalling. In line with JH having a conserved role in regulating division of labour in social wasps, we show that JH in this species indeed affected behavioural maturation and division of labour in the worker caste. In particular, topical application of the JH analogue methoprene onto workers accelerated behavioural maturation and hastened the onset of foraging, thereby significantly decreasing the time they spent conducting activ
