To learn the evolutionary trajectories of caste differentiation in eusocial species is a major goal of sociobiology. We present an explanatory framework for caste evolution in the eusocial wasp genus Polistes (Vespidae), which is a model system for insect eusocial evolution. We hypothesize that Polistes worker and gyne castes stem from two developmental pathways that characterized the bivoltine life cycle of a solitary ancestor. Through individual-based simulations, we show that our mechanistic… 

Wasps ( Family : Vespidae )

Mechanisms that influence the development of reproductive castes—in both larval and adult stages—and mechanisms that influence non-reproductive division of labour among workers are explored.

Simultaneous Analysis and the Origin of Eusociality in the Vespidae (Insecta: Hymenoptera)

A new phylogenetic analysis of the Vespidae based on what is by far the largest taxon sample to include molecular data, and the largest phenotypic character dataset ever compiled, supports a single origin of eusociality.

Eusocial Evolution in Termites and Hymenoptera

Substantial overlap occurs in the genes controlling caste and the shift of parental care to offspring via heterochrony, suggesting ecological pressures lead to co-option of similar developmental mechanisms in the Isoptera and Hymenoptera.

A new model for caste development in social wasps

A model of how vibrational signaling in the context of feeding larvae could interact with nutritional input to account for the developmental patterns seen in these wasps is presented.

Social evolution in the sweat bee Halictus scabiosae

This thesis investigated female reproductive strategies in the primitively eusocial bee Halictus scabiosae, with a focus on the role of helpers, in order to get insight into the mechanisms governing the evolution and maintenance of eussociality.

Alternative Nesting Strategies of Polistine Wasps in a Subtropical Locale

A new and unique view of the nesting biology of social wasps is provided by comparing and contrasting the phenology of species in two genera, Polistes and Mischocyttarus, in a context that sheds light on the life history and evolution of this group.

Multigene phylogeny reveals eusociality evolved twice in vespid wasps

A phylogeny of Vespidae based on data from four nuclear gene fragments and representatives from all six extant subfamilies indicates two independent origins of vespid eusociality, once in the clade Polistinae+Vespinae andonce in the Stenogastrinae.

A unified model of Hymenopteran preadaptations that trigger the evolutionary transition to eusociality

It is shown that the joint evolution of helping behaviour and maternal sex ratio adjustment can synergistically trigger both a behavioural change from solitary to eusocial breeding, and a demographic change from a life cycle with two reproductive broods to aLife cycle in which an unmated cohort of female workers precedes a final generation of dispersing reproductives.

Molecular Evolution of Insect Sociality: An Eco-Evo-Devo Perspective.

Available data on molecular evolution of insect sociality is reviewed and key biotic and abiotic factors influencing social insect genomes are highlighted and both phylogenetic and ecological evolutionary developmental biology perspectives are suggested for a more synthetic view of molecular evolution in insect societies.



The social biology of Ropalidia marginata : toward understanding the evolution of eusociality

The goal of this book is to provide a ontological basis for a theory of social evolution that can be applied to the study of human evolution.

Reproductive caste determination in eusocial wasps (Hymenoptera: Vespidae).

Correlative and experimental studies indicate that differences in nutrition during larval development are often the basis of pre-imaginal caste determination, which has important implications for the roles of subfertility and manipulation by nest mates in the evolution of eusocial behavior.

Book review of "The social biology of Ropalidia marginata: toward understanding the evolution of eusociality" by Raghavendra Gadagkar, University of Chicago Press, Cambridge (Massachusetts)

The author's dream of understanding the evolution of that pinnacle of social life in animals, eusociality, has been a fruitful one, and the volume will be of significant value to all those interested in studying and understanding the dynamics of social systems, whatever species they happen to study.

Developmental and Physiological Determinants of Caste in Social Hymenoptera: Evolutionary Implications

A developmental view of the evolution of societies is presented and two complementary questions are raised regarding the relationship between social structure and the factors that determine physical or physiological differences among females are raised.

Dispersal of first "workers" in social wasps: causes and implications of an alternative reproductive strategy.

Evidence that foundresses may actively limit the sizes of first-emerging females, perhaps to decrease the probability that the latter can effectively challenge foundresses for reproductive rights is presented.

Caste Systems. (Book Reviews: Social Insects. An Evolutionary Approach to Castes and Reproduction.)

Caste Development, Reproductive Strategies, and Control of Fertility in Honey Bees and Stingless Bees, and Regulatory Steps in Caste Development of Eusocial Bees are described.

Food Quantity AffectTraits of Offspring in the Paper Wasp Polistes metricus (Hymenoptera: Vespidae)

The data suggest that Polistes metricus colonies are partly able to respond to different nutritional conditions by allocating excess food to increase the number of gynes at the expense of workers.

Partial bivoltinism may cause alternating sex-ratio biases that favour eusociality

A model for the evolution of sex ratios in species having two generations per year with an asymmetrical pattern of overlap between the generations is described, showing one particular way in which ecological and genetic variables may interact to encourage the emergence of eusociality in some species and to discourage it in others.


A "polyg ynous family hypothesis" is proposed as an alternative to the "subsocial" and "semisocial" hypotheses for the evolution of insect sociality.
