Bipartite network analysis of ant-task associations reveals task groups and absence of colonial daily activity [PDF]

open access: yesRoyal Society Open Science, 2021
Social insects are one of the best examples of complex self-organized systems exhibiting task allocation. How task allocation is achieved is the most fascinating question in behavioural ecology and complex systems science.

Nest wax triggers worker reproduction in the bumblebee Bombus terrestris [PDF]

open access: yesRoyal Society Open Science, 2016
Social insects are well known for their high level of cooperation. Workers of the primitively eusocial bumblebee Bombus terrestris are able to produce male offspring in the presence of a queen.

Ant queens increase their reproductive efforts after pathogen infection [PDF]

open access: yesRoyal Society Open Science, 2017
Infections with potentially lethal pathogens may negatively affect an individual's lifespan and decrease its reproductive value. The terminal investment hypothesis predicts that individuals faced with a reduced survival should invest more into ...

Wolbachia in the flesh: symbiont intensities in germ-line and somatic tissues challenge the conventional view of Wolbachia transmission routes [PDF]

open access: yes, 2014
Symbionts can substantially affect the evolution and ecology of their hosts. The investigation of the tissue-specific distribution of symbionts (tissue tropism) can provide important insight into host-symbiont interactions.

Resistance and Vulnerability of Honeybee (Apis mellifera) Gut Bacteria to Commonly Used Pesticides

open access: yesFrontiers in Microbiology, 2021
Agricultural and apicultural practices expose honeybees to a range of pesticides that have the potential to negatively affect their physiology, neurobiology, and behavior.

Cuticular hydrocarbon reception by sensory neurons in basiconic sensilla of the Japanese carpenter ant

open access: yesFrontiers in Cellular Neuroscience, 2023
To maintain the eusociality of a colony, ants recognize subtle differences in colony-specific sets of cuticular hydrocarbons (CHCs). The CHCs are received by female-specific antennal basiconic sensilla and processed in specific brain regions. However, it

A strong immune response in young adult honeybees masks their increased susceptibility to infection compared to older bees [PDF]

open access: yes, 2012
Honeybees, Apis mellifera, show age-related division of labor in which young adults perform maintenance ("housekeeping") tasks inside the colony before switching to outside foraging at approximately 23 days old. Disease resistance is an important feature

Biology of Pseudacteon Decapitating Flies (Diptera: Phoridae) That Parasitize Ants of the Solenopsis saevissima Complex (Hymenoptera: Formicidae) in South America

open access: yesInsects, 2020
Pseudacteon flies (Diptera: Phoridae) parasitize individual ant workers, causing decapitation of the host during pupariation. Phorid flies that attack South American fire ants in the Solenopsis saevissima (Smith) complex are distributed across a wide ...

Detecting rare asymmetrically methylated cytosines and decoding methylation patterns in the honeybee genome [PDF]

open access: yesRoyal Society Open Science, 2017
Context-dependent gene expression in eukaryotes is controlled by several mechanisms including cytosine methylation that primarily occurs in the CG dinucleotides (CpGs).

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.
