Multiple nest entrances alter foraging and information transfer in ants

Bertrand Eric Collignon

The ecological success of ants relies on their ability to discover and collectively exploit available resources. In this process, the nest entrances are key locations at which foragers transfer food and information about the surrounding environment. We ass ...

Drosophila melanogaster cloak their eggs with pheromones, which prevents cannibalism

Yury Tsybin, Laure Menin, Konstantin Nagornov

Oviparous animals across many taxa have evolved diverse strategies that deter egg predation, providing valuable tests of how natural selection mitigates direct fitness loss. Communal egg laying in nonsocial species minimizes egg predation. However, in cann ...

Insect-Inspired Visual Perception for Flight Control and Collision Avoidance

Julien Jean Denis Nicolas Lecoeur

Flying robots are increasingly used for tasks such as aerial mapping, fast exploration, video footage and monitoring of buildings. Autonomous flight at low altitude in cluttered and unknown environments is an active research topic because it poses challen ...

The Role of Lipid Competition for Endosymbiont-Mediated Protection against Parasitoid Wasps in Drosophila

Bruno Lemaitre, Fanny Schüpfer, Juan Camilo Paredes Escobar, Jeremy Keith Herren

Insects commonly harbor facultative bacterial endosymbionts, such as Wolbachia and Spiroplasma species, that are vertically transmitted from mothers to their offspring. These endosymbiontic bacteria increase their propagation by manipulating host reproduct ...

Effects of ploidy and sex-locus genotype on gene expression patterns in the fire ant Solenopsis invicta

Chitsanu Khurewathanakul, Oksana Riba Grognuz, Laurent Keller

Males in many animal species differ greatly from females in morphology, physiology and behaviour. Ants, bees and wasps have a haplodiploid mechanism of sex determination whereby unfertilized eggs become males while fertilized eggs become females. However, ...

Although it is a human pathogen, Vibrio cholerae is a regular member of aquatic habitats, such as coastal regions and estuaries. Within these environments, V. cholerae often takes advantage of the abundance of zooplankton and their chitinous molts as a nut ...

Pseudomonas entomophila is an entomopathogenic bacterium that infects and kills Drosophila. P. entomophila pathogenicity is linked to its ability to cause irreversible damages to the Drosophila gut, preventing epithelium renewal and repair. Here we report ...

Artificial pheromone for path selection by a foraging swarm of robots

Valentin Longchamp, Simon Garnier

Foraging robots involved in a search and retrieval task may create paths to navigate faster in their environment. In this context, a swarm of robots that has found several resources and created different paths may benefit strongly from path selection. Path ...

Associative learning is known to modify foraging behavior in numerous parasitic wasps. This is in agreement with optimal foraging theory, which predicts that the wasps will adapt their responses to specific cues in accordance with the rewards they receive ...
