SummaryFood-sharing experiments were performed with laboratory colonies of Solenopsis invicta containing 1000, 10,000, or 20,000 workers and starved for 0, 3, 7, or 14 days. The effect of these variables was measured on the uptake of radioactive sugar water (1 M) by 1% of the colony's workers and on the trophallactic flow of food from these foragers to the remainder of the colony.Patterns of food distribution in small colonies differed significantly from those in larger nests. In 1000-ant nests… 

Effects of Colony Composition and Food Type on Nutrient Distribution in Colonies of Monomorium orientale (Hymenoptera: Formicidae)

A laboratory study on the distribution of carbohydrates, proteins, and lipids, which were represented by respective food sources, in M. orientale colonies revealed that carbohydrates had rapid distribution, with >60% of the colony indicated in 24 h, in all colony conditions.

The influence of forager number and colony size on food distribution in the odorous house ant, Tapinoma sessile

The odorous house ant, Tapinoma sessile (Say), was used as a model species to investigate the factors affecting the rate of spread of liquid carbohydrate food throughout a colony and found that the number of individuals receiving food increases with increasing colony size, while the per capita amount of food decreases.

Simplified approaches to determine the attractant preference of Solenopsis invicta (Hymenoptera : Formicidae)

The results showed that of the four ant densities investigated, the medium ant density most consistently had more workers at the food lures than the other ant density situations, and that significantly fewer foragers were observed in the foraging areas when a queen was present, then when the queen was absent.

Control of food influx by temporal subcastes in the fire ant, Solenopsis invicta

It is found that starved foragers increase the honey entering the colony and the quantity of food brought in by the foragers is regulated via discriminatory solicitation by reserves in response to the nutritional needs of the nurses.

How do groups of red imported fire ants (Hymenoptera: Formicidae) feed on a droplet of sugar water?

Both laboratory and field studies showed colony‐level variations in sugar‐water feeding and field investigation showed that surround feeding was most frequently performed by S. invicta foragers; however, cover feeding was not observed under field conditions during this study.

Sampling Efficacy for the Red Imported Fire Ant Solenopsis invicta (Hymenoptera: Formicidae)

An interactive model, whereby surveillance managers can alter trap type, density, and duration parameters to estimate the probability of detecting specified or unknown S. invicta colony sizes is created, to support decision makers who need to balance the sampling cost and risk of failure to detect fire ant colonies.

Spatial organization in ants’ nests: does starvation modify the aggregative behaviour of Lasius niger species?

Compared the aggregation dynamics of inner-nest workers and foragers having undergone either a short or a long-lasting starvation period, it is shown that an increased foraging response to food shortage cannot be explained by changes in the tendency of nestmates to aggregate within the nest.

Experimentally guided development of a food bait for European fire ants

A food bait that elicits a strong foraging response from EFAs, has extended shelf life, and is cost‐effective to produce is developed, and freeze‐drying may retain essential nutrients and/or aroma constituents.

Brood Arrangement and Food Distribution Among Larvae Under Different Colony Conditions in the Pharaoh's Ant, Monomoriumpharaon/'s

The Pharaoh's ant, Monornorium pharaonis (L.) is one of the most widely distributed and most successful tramp species in the Formicidae family and it is essential to understand the feeding behavior of this species to further enhance the efficiency of baiting.

Carbohydrate regulation in relation to colony growth in ants

It is demonstrated that ants regulated carbohydrate intake at both a collective and individual level in response to changes in the concentration of available sucrose solution, colony demography and larval growth, and showed that ants defended a carbohydrate `intake target' by allowing them to select among sugar solutions of different concentration.



Growth and Development of Colonies of the Red Imported Fire Ant, Solenopsis invicta

A study of new colonies of Solenopsis invicta Buren showed that from their inception in early May until fall when weather stops development, the colonies had grown from a single queen and 15–20

Evidence of a Replete Caste in the Fire Ant Solenopsis invicta

The present paper reports the results of the studies made of this phenomenon, which was puzzling because the oil and dye would not have been present if normal food exchange, metabolism, and excretion had occurred after the initial feeding of the ants.

Division of labor in fire ants based on physical castes (Hymenoptera: Formicidae: Solenopsis).

?Division of labor in two species of fire ants, Solenopsis invicta and S. geminata, was studied by a "cross-indexing" method that employed (1) the description of the total behavioral repertory of

The Foraging Behaviour of the Ant, Formica Fusca

Analysis of the behaviour of recruited foragers shows they behave more like primary foragers from satiated nests than primary forager from their own nests, and factors influencing the kind of food-sharing behaviour shown are discussed.

Feeding in the Larvae of the Imported Fire Ant, Solenopsis invicta: Behavior and Morphological Adaptations

Adult workers of the imported fire ant feed liquid foods to larvae of all instars, and feed solid proteinaceous foods only to the 4th instar, and the relationship of larval feeding to a possible method of fire ant control is discussed.

Communication and recruitment in pharaoh's ant, Monomorium pharaonis (L.)

Food distribution within laboratory colonies of the argentine ant,Tridomyrmex humilis (Mayr)

The purpose of th i s s tudy was to examine the feeding of food dist r i bu t ion wi th colonies of the Argent ine ant, lridomyrmex humilis (Mayr) and to develop control methods based on the use of baits.

The Distribution of an Oil, Carbohydrate, and Protein Food Source to Members of the Imported Fire Ant Colony

Using a dye technique, the distribution of sugar, oil, and protein food sources among the colony of Solenopsis saevissima richteri Ford was studied and larvae received the greatest percentage of the oil.
