A striking feature of hymenopteran societies is the general absence of male workers. There are some reports of males feeding larvae in some social wasps, but not in the extensively studied Ropalidia marginata. By providing excess food and by removing the females, we investigated whether males are incapable of feeding larvae or lack opportunities to do so. Males fed larvae with probabilities and rates comparable to those of females, suggesting that lack of preadaptation to feed larvae does not… Expand

Figures from this paper

Natural history and behaviour of the primitively eusocial wasp Ropalidia marginata (Hymenoptera: Vespidae): a comparison of the two sexes
TLDR
It is found that just as nests of this species are found throughout the year, so are the males, and that males showed fewer dominance and subordinate behaviours and being solicited behaviour and more feeding self and soliciting behaviours. Expand
Social and genetic structure in colonies of the social wasp Microstigmus nigrophthalmus
TLDR
This study provides the finest analysis of genetic structure so far in an apoid wasp, and indicates that the form of sociality varies greatly between species of Microstigmus. Expand
Is There Division of Labor in Cooperative Pseudoscorpions? An Analysis of the Behavioral Repertoire of a Tropical Species
TLDR
This is the first study clearly demonstrating division of tasks in arachnids and suggests that specialization is an adaptative and evolutionarily old trait in this species, P. nidificator. Expand
Active and effective nest defence by males in a social apoid wasp
TLDR
Evidence of active and effective nest defence in males of the social apoid wasp Microstigmus nigrophthalmus is presented, and it is shown that males can perform acts that benefit their colony. Expand
Behavioural and morphological dimorphism of the sexes: an account of two primitively eusocial wasps
TLDR
Novel methods are used to compute and compare behavioural diversity and behavioural richness and show that females of both species are behaviourally richer and more diverse than the males. Expand
Hormone-mediated dispersal and sexual maturation in males of the social paper wasp Polistes lanio
TLDR
Delayed dispersal from the natal nest by male paper wasps is regulated by juvenile hormone and associated with sexual maturation, which highlights the wide role of JH in social hymenopteran behaviour, with parallel ancestral functions in males and females. Expand
eview he trap of sex in social insects : From the female to the male erspective
The phenotype of male Hymenoptera and the peculiar role of males has been neglected and greatly understudied, given the spectacular cooperative behavior of female social insects. In social insectsExpand

The trap of sex in social insects: From the female to the male perspective
TLDR
Male behavior in social Hymenoptera is reviewed beyond sex stereotypes: the subtle role of "drones" in the colony, the lack of armaments and ornaments, the explosive mating crowds, the "endurance" race, the cognitive bases of the "choosy" male and his immune defense. Expand
Nesting of Ceratina nigrolabiata, a biparental bee
TLDR
C. nigrolabiata is unique among bees due to its biparental behavior, but it has also uncommon traits of nesting biology among Ceratina bees, e.g. fast offspring development in comparison with provisioning rate, and high proportion of nests which are closed and abandoned by mother. Expand

The Function of Male Dominance in the Eusocial Wasp, Mischocyttarus mastigophorus (Hymenoptera: Vespidae)
TLDR
It is speculated that increased male longevity may be selectively advantageous in tropical species such as M. mastigophorus that found new colonies throughout much or all of the year, when females initiate new nests over much of theyear, individual males' mating opportunities may be temporally distributed, favoring longer adult lifespans.

Division of labor in post-emergence colonies of the primitively eusocial waspPolistes instabilis de Saussure (Hymenoptera: Vespidae)
TLDR
Polyethism was quantified in post-emergence colonies of the primitively eusocial wasp, Polistes instabilis, and compared to polyethism in a sympatric advanced eus SOC, Polybia occidentalis, showing less individual specialization on foraging tasks and less partitioning of foraged materials with nestmates, suggesting that these characteristics of polyethisms have been modified during the evolution of advanced insect societies.

TLDR
It is suggested that elevated susceptibility in haploid males has shaped the evolution of social behaviour in haplodiploid species and will select for behavioural adaptations that limit males’ exposure to pathogens and that limit male transmission of pathogens within and between colonies. Expand

TLDR
These results confirm a previously observed pattern of larval provisioning and, for the first time, demonstrate adult nourishment to be concomitant with the provisioning behavior. Expand

An overview of the current state of scientific knowledge about social evolution in ants is presented and how studies on ants have contributed to an understanding of many fundamental topics in behavioural ecology and evolutionary biology is shown. Expand
Book review of "The social biology of Ropalidia marginata: toward understanding the evolution of eusociality" by Raghavendra Gadagkar, University of Chicago Press, Cambridge (Massachusetts)
TLDR
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.

TLDR
A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”. Expand
