TLDR
Sugary solution intake behavior by Odontomachus chelifer (Latreille) is studied and its ability to ingest mildly viscous fluids could be related to its capacity to ingest other viscous fluid present in its diet.Abstract:
Sugary solution intake behavior by Odontomachus chelifer (Latreille), is studied. The feeding mechanism involved is described. Effects of sucrose concentration and solution viscosity on ingested load, feeding time and rate of liquid intake are assessed. Suction was always the feeding mechanism, regardless of concentration or viscosity of the solution. There were no differences in loads ingested for concentrations of up to 30% w/w, but feeding took longer at this concentration. Liquid intake rates were higher at the lowest concentrations. Above 40% w/w, values of all three variables were smaller. O. chelifer’s ability to ingest mildly viscous fluids could be related to its capacity to ingest other viscous fluids present in its diet.read more

Laboratory and field insights into the dynamics and behavior of Argentine ants, Linepithema humile, feeding from hydrogels.
TL;DR: In this article, the authors study the abilities of Argentine ants to imbibe liquid from hydrogels and quantified feeding behavior with different sucrose concentrations (20, 30, 40 and 50% w/w).

Feeding behavior and social interactions of the Argentine ant Linepithema humile change with sucrose concentration
TL;DR: It is shown here that sucrose concentration affects feeding dynamics and modulates decision making related to individual behavior and social interactions of foragers.

Intra‐ and interspecific variation in trophic ecology of ‘predatory’ ants in the subfamily Ponerinae
TL;DR: The characterisation of energy flow through communities is a primary goal of ecology and measuring intra‐ and interspecific variation in their trophic ecology is essential for understanding the role of ants as predators of insect communities.

An Approach to Observing and Quantifying Real-Time Mandibular Muscle Topology in the Trap-Jaw Ant Odontomachus monticola by Synchrotron Imaging
TL;DR: This study provides the first visualization evidence which validates that the mandible strike is facilitated by the contraction of adductor muscles, without the activation of abductor muscles.

All sugars ain't sweet: selection of particular mono-, di- and trisaccharides by western carpenter ants and European fire ants.

TL;DR: In this article, the authors tested the hypotheses that western carpenter ants, Camponotus modoc, seek honeydew excretions from Cinara splendens aphids based solely on the presence of sugar constituents (H1), prefer sugar solutions containing aphid-specific sugars (H2) and preferentially seek sugar solutions with higher sugar content (H3).

The Evolutionary Ecology of Ant-Plant Mutualisms.
M. V. Brian,Andrew J. Beattie +1 more
TL;DR: Beattie as discussed by the authors reviewed the natural history of ant-plant interactions, discussed the scientific evidence for the mutualistic nature of these relationships, and reached some conclusions about the ecological and evolutionary processes that mold them.

The evolutionary ecology of ant-plant mutualisms
TL;DR: Professor Beattie reviews the fascinating natural history of ant–plant interactions, discusses the scientific evidence for the mutualistic nature of these relationships, and reaches some conclusions about the ecological and evolutionary processes that mold them.
Book
The ecology and evolution of ant-plant interactions
TL;DR: The dynamics of ant-plant interactions are synthesized, including the sources of variation in their outcomes, to provide a better understanding of the unparalleled success of these two remarkable groups, of interspecific interactions in general, and, ultimately, of terrestrial biological communities.

Evaluating Responses of Honey Bees to Sugar Solutions Using an Artificial-Flower Feeder
TL;DR: An artificial-flower feeder was designed to compare the acceptibility of sugar solutions to foraging honey bees, and discrimination against the least preferred solutions was apparently reduced and then eliminated as the number of bees imbibing was increased.
