SummaryThe ultrastructure and excretions of the hindgut of larvæ of the imported fire ant,Solenopsis invicta Buren, is described. The anterior or base of the hindgut is closed and rooted (via the “dome”) in the posterior wall of the midgut, and is composed of basal cells of both the malpighian tubules and the small intestine (ileo-colon). The ileo-colon opens via a rectal valve into the rectum and transfers uric acid (white excretion) secreted by the malpighian tubules, into the rectum. The… 

Excretion of Phosphoric Acid by Red Imported Fire Ants, Solenopsis invicta Buren (Hymenoptera: Formicidae)

The presence of phosphoric acid in larval anal liquid shows that red imported fire ants excrete phosphate acid, which is primarily of metabolic origin.

Trophallaxis: the functions and evolution of social fluid exchange in ant colonies (Hymenoptera: Formicidae)

The analyses support the idea that stomodeal trophallaxis has become a fixed aspect of colony life primarily in species that drink liquid food and that the adoption of this behavior was key for some lineages in establishing ecological dominance.

In the laboratory, red imported fire ants were able to build their nest using moistened silica gel as the only building material, providing an opportunity to establish a profile of ant-derived chemicals in nest material without the presence of any soil-borne artifacts.

Effects of Larval Secretions on Queen Fecundity in the Fire Ant

A case study on the red imported fire ant, Solenopsis invicta Buren, is reported, demonstrating that larval excretory products amplified queen fecundity rather than larval fecal fluids, larval saliva, or nutrients.

Study of Midgut Bacteria in the Red Imported Fire Ant, Solenopsis invicta Büren (Hymenoptera: Formicidae)

New SEM and TEM techniques revealed a possible functional association of endosymbiotic bacteria with the insect host, and it also showed the absence of bacteria inside the Red Imported Fire Ant midgut.



Fine-structural changes in relation to ion and water transport in the rectal papillae of the blowfly, Calliphora.

It is proposed that the structural design of the rectal papillae favours the application of double-membrane theory to explain the reabsorption of water against osmotic gradients as a consequence of an active transport of solutes into enclosed spaces.

Developmental Morphology of Larvae and Eggs of the Imported Fire Ant, Solenopsis invicta

The egg of the imported fire ant, Solenopsis invicta Buren, becomes embryo-like before the larva emerges, and a simple method for determining the developmental stage of live larvae of the importing fire ant is provided.

Fine-structural localization of adenosine triphosphatase in the rectum of Calliphora.

It is proposed that the ATPase localized on the stacks of lateral plasma membrane may be involved with ion secretion into the intercellular spaces to create the osmotic gradient necessary to extract water from the lumen.

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.


In a survey conducted in the Southeastern United States, one colony in a sample of 1,007 colonies of the red imported fire ant, Solenopsis invicta Buren, was infected with a microsporidium (Protozoa:

Comparative analysis of the hindgut in two species of protura (Insecta, Apterygota)

The proturan hindgut consists of two regions, with different ultrastructure, and is organized into three primary longitudinal folds alternating with three smaller, secondary ones.

Proprioception In Insects

Comparison of the campaniform sensilla of Periplaneta with that of the vertebrate limb reveals an absence of qualitative sensitivity that may have an important bearing on the question of the evolution of behaviour.
