A novel social polymorphism in a primitively eusocial bee.
Halictine sweat bees (Hymenoptera, Halictidae) are model organisms for the evolution of altruism, reproductive castes, and eusocial colony organization. Halictine social behavior is not only extremely variable, but also ecologically and evolutionarily labile. Among social species, colony social organization ranges from communal societies of egalitarian females to eusocial and semisocial ones wi...
متن کاملDominance behaviour and regulation of foraging in the primitively eusocial wasp Ropalidia marginata (Lep.) (Hymenoptera: Vespidae).
Ropalidia marginata is a primitively eusocial, polistine wasp widely distributed in peninsular India. In spite of its primitively eusocial status, queens of R. marginata are surprisingly docile and behaviourally non-dominant (except during the first week or so of their careers as queens). Yet they successfully maintain reproductive monopoly throughout their careers, probably through the use of ...
متن کاملA possible novel function of dominance behaviour in queen-less colonies of the primitively eusocial wasp Ropalidia marginata.
Unlike the queens of other primitively eusocial species, Ropalidia marginata queens are strikingly docile and non-aggressive individuals, never at the top of the behavioural dominance hierarchy of their colonies. Nevertheless, these queens are completely successful at suppressing worker reproduction, suggesting that they do not use aggression but employ some other mechanism (e.g. pheromones) to...
متن کاملHelping effort in primitively eusocial wasps
In primitively eusocial and cooperatively breeding societies, there is substantial individual variation in helping effort that is not accounted for by variation in genetic relatedness. In primitively eusocial wasps, helpers have a significant chance of inheriting breeding positions. Recent models suggest that because helpers with greater expected future fitness have more to lose, they should in...
متن کاملLife History and Social Evolution of the Primitively Eusocial Bee Augochlorella striata (Hymenoptera: Halictidae)
Life history parameters of the primitively eusocial bee Augochlorella striata (Hymenoptera: Halictidae) are summarized for a population in central New York, and analyzed with respect to the evolutionary maintenance of eusociality in this species. High mortality (39%) of solitary foundresses and low mortality (12%) of social colonies indicate severe ecological constraints limiting independent (s...
