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… Expand

Morphology and ultrastructure of the hindgut fermentation chamber of a melolonthine beetle Holotrichia parallela (Coleoptera: Scarabaeidae) during larval development.
The morphology and ultrastructure of the hindgut fermentation chamber of a melolonthine beetle, Holotrichia parallela, showed that the anterior portion of the hindergut expanded into a characteristic lobe-like structure described as a fermentation chamber, suggesting that it may have an important role in the symbiotic relationship between microbes and their insect hosts.

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. Expand
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. Expand
Trophallaxis: the functions and evolution of social fluid exchange in ant colonies (Hymenoptera: Formicidae)
Trophallaxis is a complex social fluid exchange emblematic of social insects and of ants in particular. Trophallaxis behaviors are present in approximately half of all ant genera, distributed over 11Expand

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. Expand
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. Expand


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. Expand
Internal anatomy of the fourth instar larva of the imported fire ant, Solenopsis invicta buren (Hymenoptera : Formicidae)
Abstract We describe the internal anatomy of fourth instar larvae of the economically important and much studied imported fire ant, Solenopsis invicta Buren to form the basis for studies on theirExpand
Structure and function of rectal pads in Blattella and Blaberus with respect to the mechanism of water uptake
The morphology of the rectal pads of two cockroaches is described and the possible role of secondary cells is discussed, it is proposed that the secondary cells reabsorb solute from the sinus and that this solute can be recycled through the pad cells. Expand
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. Expand
Active transport of chloride and sodium by the rectal chamber of the larvae of the dragonfly, Uropetala carovei
The rectum of Uropetala carovei is capable of transporting chloride ions into the haemolymph from the medium against an electrochemical gradient, at a rate (in 0.5 mM sodium chloride) of 0.3 to 0.5Expand
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. Expand
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. Expand
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:Expand
