Monogamy promotes altruistic sterility in insect societies [PDF]

Royal Society Open Science, 2018
Monogamy is associated with sibling-directed altruism in multiple animal taxa, including insects, birds and mammals. Inclusive-fitness theory readily explains this pattern by identifying high relatedness as a promoter of altruism.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

The impact of social complexity on the efficacy of natural selection in termites

Peer Community Journal
In eusocial species, reproduction is monopolized by a few reproductive individuals.From the perspective of population genetics, this implies that the effective population size (Ne) of these organisms is likely to be smaller compared to solitary species ...

Social behaviour in bees influences the abundance of Sodalis (Enterobacteriaceae) symbionts [PDF]

Royal Society Open Science, 2018
Social interactions can facilitate transmission of microbes between individuals, reducing variation in gut communities within social groups. Thus, the evolution of social behaviours and symbiont community composition have the potential to be tightly ...

The Molecular Substrates of Insect Eusociality. [PDF]

Annu Rev Genet
The evolution of eusociality in Hymenoptera—encompassing bees, ants, and wasps—is characterized by multiple gains and losses of social living, making this group a prime model to understand the mechanisms that underlie social behavior and social complexity. Our review synthesizes insights into the evolutionary history and molecular basis of eusociality.

Form, function, and evolution of worker–worker social carrying in ants

Insect Science, EarlyView.
Social carrying is a widespread ant recruitment behavior in which one worker physically transports another, usually during nest relocation. Across 62 species, phylogenetic analyses suggest that it originated as a stereotypical, coordinated behavior, with carrying posture largely conserved within subfamilies. Its occurrence across colony sizes indicates

Potential Correlation Between Bombus lantschouensis Thoracic Morphology and Flight Behavior

Integrative Zoology, EarlyView.
Potential correlation between Bombus lantschouensis thoracic morphology and flight behavior. ABSTRACT Remarkably little modern work has investigated the thoracic structures of insects and their relationship to flight locomotion. Most studies focus exclusively on either morphology or flight kinematics.

Origin and evolution of eusociality: a perspective from studying primitively eusocial wasps [PDF]

Journal of Genetics, 1990
Eusocial insects are those that show overlap of generations, cooperative brood care and reproductive caste differentiation. Of these, primitively eusocial insects show no morphological differences between reproductive and worker castes and exhibit considerable flexibility in the social roles that adult females may adopt.

Bayesian and parsimony analyses based on morphological data reveal a new genus of spilomenine wasps (Hymenoptera: Crabronidae: Pemphredoninae) from Australia [PDF]

Zoologia (Curitiba)
Pemphredoninae are a very large lineage of crabronid wasps with more than a thousand species. In this lineage, the subtribe Spilomenina stand out for containing the smallest apoid wasps and by exhibiting relatively complex social behavior such as female ...

Balancing Life History Investment Decisions in Founding Ant Queens

Frontiers in Ecology and Evolution, 2020
Reproduction is a very critical step in the life of an organism. Females must balance their investment in different life-history traits while reproducing.
