Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

Atta cephalotes (Hymenoptera: Myrmicinae) is colonizing urban areas in Cali, Colombia

Urban Ecosystems, 2023
Abstract Numerous studies have examined the effect of invasive species on biodiversity in urban environments, however, few of them have investigated the role of native species while turning into invasive pests. In Colombia, Atta cephalotes , a native leaf-cutting ant (LCA ...

Waste management in the stingless bee Melipona beecheii Bennett (Hymenoptera: Apidae) [PDF]

, 2014
Waste management is important in insect societies because waste can be hazardous to adults, brood and food stores. The general organization of waste management and the influence of task partitioning, division of labor and age polyethism on waste ...

Effects of climate change on plant resource allocation and herbivore interactions in a Neotropical rainforest shrub

Ecology and Evolution, Volume 12, Issue 8, August 2022., 2022
Climate change could impact plant–herbivore systems directly by altering species traits or abundances or indirectly by altering the strength and direction of the relationships that govern organismal strategies and interactions. It appears that, in this Neotropical system, increased CO2 concentration and temperature may cause indirect, cascading ...

The ant abdomen: The skeletomuscular and soft tissue anatomy of Amblyopone australis workers (Hymenoptera: Formicidae)

Journal of Morphology, Volume 283, Issue 6, Page 693-770, June 2022., 2022
The ant abdomen is critically understudied, despite its functional, evolutionary, and systematic importance. Using physical dissection, scanning electron microscope, histology, and microcomputed tomography, we provide the first complete treatment of the skeletomusculature, exocrine glands, and other major organs of the abdomen.

Spatio-temporal permanence and plasticity of foraging trails in young and mature leaf-cutting ant colonies (Atta spp.) [PDF]

, 2005
The distribution and formation of foraging trails have largely been neglected as factors explaining harvesting patterns of leaf-cutting ants.We applied fractal analysis, circular, and conventional statistics to published and newly recorded trailmaps of ...

Forager Polymorphism and Foraging Ecology in the Leaf-Cutting Ant, Atta colombica

Psyche: A Journal of Entomology, 1995
I compare forager size and foraging selectivity of the leaf-cutting ant Atta colombica and that of its close relative Atta cephalotes. In both species, larger foragers cut fragments of greater mass and area, and at vegetation sources of greater specific ...

Bimodal alarm signals modulate responses to monomodal alarm signals in Camponotus modoc carpenter ants. [PDF]

Insect Sci
Distressed Camponotus modoc carpenter ants emit alarm pheromone and produce vibratory alarm signals. Presented as a monomodal signal, the pheromone attracts nestmates, whereas vibratory signals cause nestmates to “freeze” or to run fast. Sensing a bimodal signal complex, nestmates are less attracted to pheromone but stay “frozen” longer which seems ...
