Abstract

The genomes of two bumblebee species characterized by a lower level of sociality than ants and honeybees provide new insights into the origin and evolution of insect societies.

Abstract

This paper describes the complex life cycle and the occurrence of reproductive and soldier morphs in the trematode parasite of birds, Himasthla sp. B. The significance of this caste/eusocial system in understanding the selective forces promoting the evolution of reproductive altruism is discussed.

Abstract

Honey bees, termites and ants occupy the 'pinnacle of social evolution' with societies of a complexity that rivals our own. The sequencing of the honey bee genome will provide a strong foundation for studying the genetic basis of complex social behaviour.

Abstract

This review, with 56 references, first describes the diverse social organizations of sweat bees (subfamily Halictinae). Some case histories of multiple-foundress associations are described, including new data, and the phylogenetic position of the various types of associations are examined. From the ...

Abstract

The evolution of co-operation in insect societies is discussed with particular reference to kin selection, which also predicts potential kin conflicts (over, for example, caste determination, male parentage, colony sex ratio). It is concluded that understanding how these conflicts are resolved is a ...

Abstract

A single genomic element marked by the Gp-9 gene was found to be responsible for the existence of 2 distinct forms of social organization, polygyne and monogyne, in the fire ant Solenopsis invicta. In laboratory experiments using S. invicta collected from Georgia, USA, this genetic factor...

Abstract

A general mechanism is described for the social suppression of within-group selfishness that follows from Hamilton's rule combined with a multilevel selection approach to asymmetrical, 2-person groups: If it pays a group member to behave selfishly (i.e., increase its share of the group's...

Abstract

Primary (egg) sex ratios and secondary (adult) sex ratios were compared in colonies of Formica exsecta with different worker sex allocation optima, due to different degrees of relatedness asymmetry among colonies. Fifty-nine colonies were sampled on 3 adjacent islands on the southwest coast of...
