Growth Dynamics of Symbiotic Fungus and How it is Affected By Proportion of Minor Workers (Hymenoptera: Formicidae: Atta)
Leaf-cutting ants cut and load leaves into their nests to grow the obligate symbiotic fungus, the ants’ main food source and shelter for their...

Conserved worker policing in African carpenter ants with drastically different egg chemotypes
Distinctive chemical signatures have the potential to serve as discriminatory cues for olfactory recognition mechanisms. Cuticular hydrocarbon (CHC)...

Olfactory sensitivity differentiates morphologically distinct worker castes in Camponotus floridanus
BackgroundCamponotus floridanus ant colonies are comprised of a single reproductive queen and thousands of sterile female offspring that consist of...
-
Worker-dependent gut symbiosis in an ant
The hallmark of eusocial insects, honeybees, ants, and termites, is division of labor between reproductive and non-reproductive worker castes. In...

Apis mellifera Worker Bees Selected for Varroa-sensitive Hygiene Show Higher Specific Sensitivity and Perception Speed Towards Low Concentrations of Chemical Cues Emitted by the Brood
Varroa -sensitive hygiene (VSH) is highly influenced by the worker bee’s olfactory ability. Workers bred for VSH and non-selected control line workers...

The Pronotum of Worker of Camponotus borellii Emery (Hymenoptera: Formicidae): How Can It Affect Performance of the Head, Work Division, and Development of the Worker Caste?
In polymorphic ants, whose workers display continuous size distribution, each subcaste occupies a phenotypic space, usually with diffuse...

Origin of an evolutionary novelty: the worker phenotype of eusocial wasps
Complex problems in evolutionary biology can be approached in two ways, top down using theoretical constructs and bottom up using empirical studies...
-
Experimental increase of worker diversity benefits brood production in ants
BackgroundThe reproductive division of labor of eusocial insects, whereby one or several queens monopolize reproduction, evolved in a context of high...

Histone acetylation regulates the expression of genes involved in worker reproduction in the ant Temnothorax rugatulus
BackgroundIn insect societies, queens monopolize reproduction while workers perform tasks such as brood care or foraging. Queen loss leads to ovary...

Ecological factors affecting the abundance of worker–soldier proportions, and wood consumption of Coptotermes gestroi (Wassman) (Blattodea: Rhinotermitidae) in a tropical urban environment
Termites can regulate the environment, including temperature and humidity, within their nests. In this study, we investigated the impact of...

Worker Dimorphism in Nasute Termites Reflects Different Tasks during Food Collection
This study combines information on the differences in foraging behavior and morphological dimorphism for workers of the termite Constrictotermes...

Task partitioning in ants lacking discrete morphological worker subcastes
AbstractTask partitioning allows for efficient coordination of behavior in social insect colonies. Many task allocation studies focus on social...

Scaling relationships in Formica ants with continuous worker size variation
Social insects exhibit highly variable body plans at multiple scales: within colonies, between conspecific colonies, and across different species....

Climate and body size have differential roles on melanism evolution across workers in a worldwide ant genus
One of the main aspects associated with the diversity in animal colour is the variation in melanization levels. In ectotherms, melanism can be...

Ecology, behavior and bionomics: functional response of Heterotermes tenuis Hagen (Insecta: Blattaria: Isoptera: Rhinotermitidae) in forests of the Colombian Orinoquía
BackgroundLand use intensification may affect diversity, abundance, and functional morphological traits (FMT) related to dispersal, food acquisition,...

Long-Term Cooling (for a Year or More) the Sperm of Honey Bee Drones
AbstractThe main purpose of preservation of drone sperm is to use such sperm for instrumental insemination of queen bees, which will reproduce many...

The neuroplasticity of division of labor: worker polymorphism, compound eye structure and brain organization in the leafcutter ant Atta cephalotes
Our understanding of how sensory structure design is coupled with neural processing capacity to adaptively support division of labor is limited....
