Abstract Foraging leaf-cutting ant workers stridulate while cutting a leaf fragment. Two effects of stridulation have recently been identified: (i) attraction of nestmates to the cutting site, employing substrate-borne stridulatory vibrations as short-range recruitment signals, and (ii) mechanical facilitation of the cut via a vibratome-effect. We asked whether foragers actually stridulate to support their cutting behavior, or whether the mechanical facilitation is an epiphenomenon correlated… 

Vibration of the plant substrate generated by workers' stridulation during fungus garden cultivation in Atta laevigata (Smith) (Hymenoptera: Formicidae)

The vibration in Eucalyptus leaves generated by the stridulation of Atta laevigata (Smith) workers during processing and incorporation of the plant material into the symbiotic fungus, and to discuss its possible function.

Hitchhiking behaviour in leaf-cutter ants: An experimental evaluation of three hypotheses

The results strongly suggest that hitchhiking behaviour in Atta has multiple functions, and probably evolved as a mechanism of defence, both against potential contaminants of the symbiotic fungus and against ant parasitoids.

Fasting and chemical signals affect recruitment and foraging efficiency in the harvester ant, Pogonomyrmex vermiculatus

The results show that in Pogonomyrmex species, the ancestral character ‘solitary foraging’ shows behavioural plasticity when ants are confronted with trail pheromones stimuli and are under fasting stress.

Ants modulate stridulatory signals depending on the behavioural context

The findings suggest that vibrational signaling represents a flexible communication channel paralleling the well-known chemical communication system, and can be used to modulate stridulation based on specific needs.

Colony Wide Behavioral Contexts of Stridulation in Imported Fire Ants (Solenopsis invicta Buren)

The results suggest stridulation serves multiple functions in S. invicta, and four possible explanations for the function of stridulatory behavior of individuals, solitary wasps, and published literature on formicid stridulations are discussed.

Recruitment in starved nests: the role of direct and indirect interactions between scouts and nestmates in the ant Lasius niger

It is observed that the response of the nestmates inside the nest also greatly influence regulation of the foraging activity, and the results strongly suggest that the exit of nestmates is triggered by a chemical signal emitted by a scout.

Physical resistance as a criterion in the selection of foraging material by Acromyrmex subterraneus brunneus Forel, 1911 (Hym., Formicidae)

In inert materials such as floral sponge, polystyrene, plastic and clay, which possess different degrees of physical resistance to cutting, were offered simultaneously to five Acromyrmex subterraneus brunneus colonies, and assessed after foraging, suggesting the existence of a second time of selection of the foraged material inside the colony during cultivation of the symbiontic fungus.

Prey escorting behavior and possible convergent evolution of foraging recruitment mechanisms in an invasive ant

It is shown that food-discovering ants can recruit nearby nest mates to a large food item without returning to the nest, and a novel "escort" behavior in which additional workers accompany a transported item but do not necessarily assist in carrying it.

Foraging vibration signals attract foragers and identify food size in the drywood termite, Cryptotermes secundus

It is demonstrated that termites use substrate borne vibrations for information gathering and communication as predicted, and the effects of food size preference and attraction to other termites explained differences in behaviour between artificially generated vibration signals compared with natural recordings.

Direct ingestion of plant sap from cut leaves by the leaf-cutting ants Atta cephalotes (L.) and acromyrmex octospinosus (reich) (Formicidae, Attini)

It is suggested that leaf-cutting ants use fungus culture as a means of ‘sidestepping’ plant inhibitors and Nutrients are ingested directly from leaves when these are palatable, and the less palatable components are made available to the ants via the fungus.

Use of a Sound-Based Vibratome by Leaf-Cutting Ants

This hypothesis is supported by experiments simulating the cutting process with vibrating isolated mandibles: When tender leaves were cut, the vibration of the mandible reduced force fluctuations and thus permitted a smoother cut to be made.

LEAF‐CUTTING ANTS AND LIVE OAK: THE ROLE OF LEAF TOUGHNESS IN SEASONAL AND INTRASPECIFIC HOST CHOICE

Ants cut significantly more mature live oak leaves when leaves were sugar‐coated, indicating that there is a toughness x palatability threshold that inhibits attack by the ants.

Information about food quality influences load-size selection in recruited leaf-cutting ants

The results suggest that the decision to transfer information about the quality of the encountered food motivates a worker to return sooner to the nest, displaying recruiting behaviour, than with a full load.

Fungal hyphae as a source of nutrients for the leaf‐cutting ant Atta sexdens

Small workers lived longer than large workers when receiving fungus garden, whether or not staphylae were available, probably because they are specialized to care for the garden and can exploit it, and larger workers containing proportionately more nutritional reserves in their bodies.
