The labial gland system of larvae of the imported fire ant, Solenopsis invicta Buren

  author={Ronald S. Petralia and A. Ann Sorensen and S. B. Vinson},
  journal={Cell and Tissue Research},
SummaryThe authors describe the ultrastructure of the labial gland system in imported fire ant larvae, Solenopsis invicta Buren and present an enzyme analysis of enzymes in labial-gland secretions and midgut contents. The tubes of the labial gland produce and secrete a proteinaceous substance rich in digestive enzymes. The narrow cells of the reservoir of the gland have little or no secretory function but the lumen stores the proteinaceous secretion. The labial-gland enzymes include proteases… 

A new aspect of the role of larvae in the pharaoh's ant society (Monomorium pharaonis (L.)-Formicidae, Myrmicinae): Producer of fecundity-increasing substances to the queen

Observations of undisturbed brood chambers of the pharaoh's ant showed that mated, mature queens regularly selected large larvae lying on the bottom of the chambers, showing most of their food directly from the larvae.

Ultrastructure of the Salivary Glands of Pachycondyla (=Neoponera) villosa (Fabricius) (Formicidae: Ponerinae): Functional Changes during the Last Larval Instar

The cells of secretory region of the salivary glands of Pachycondyla (=Neoponera) villosa at the time of enzyme production presents the basal cellular membranes profusely folded and the intercellular

Nutrient Utilization during Male Maturation and Protein Digestion in the Oriental Hornet

It is suggested that larval secretions are a central nutritional resource for adult hornets that play a key role in maintaining the social structure in the colony and contribute significantly to protein uptake by both males and workers.

Macromolecular array patterns of silk gland secretion in social Hymenoptera larvae.

The cocoon, produced by most holometabolous insects, is built with silk that is usually produced by the larval salivary gland of some meliponids, wasps, and ants; the alterations in the pattern observed in the Meliponini could be a derived characteristic in the Hymenoptera.

Influence of larvae and workers on egg production of queens of the pharaoh's ant,Monomorium pharaonis (L.)

Repletes, special workers, with greatly distended gasters functioned as a buffer retarding decline of egg production by feeding the queens during short periods without larvae.

Cooperation during prey digestion between workers and larvae in the ant, Pheidole spadonia

The cooperative interactions reported here between workers and larvae extend the mechanistic and evolutionary explanations for eusociality.

Food exchange and distribution by three functional worker groups of the imported fire antSolenopsis invicta Buren

It appears that workers can discriminate between nutrient types and adjust their behaviour accordingly and colonies responded by increasing the number of foragers and active reserves.

Caracterização histoquímica e determinação do ciclo secretor da glândula salivar do tórax de Polistes versicolor (Olivier, 1791) (Hymenoptera: vespidae)

It seems that component cells in P. versicolor thoracic glands perform several, sequential role: secretory biosynthesis (TA), modification (TB, TC in duct 1, TD) and conduction of secretion (TC).

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.




Results of tests for digestive enzyme activity from mandibular and salivary glands and from foregut, midgut, and hindgut of major workers of the imported fire ant, Solenopsis richteri Forel,

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.


Results of analyses for digestive enzymes in the glands and midgut of Camponotus herculeanus (L.) indicate that carbohydrases are associated with the foregut, and lipases and proteinases are confined


Abstract Results of the analyses for digestive enzymes in the glands and midguts of five species of ants showed that invertase is usually secreted by the maxillary glands, amylase by the salivary

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.
