Extrafloral nectar, a solution of both sugars and amino acids that is produced by plants on stems and leaves, attracts ants that often protect the plants from potential herbivores. To understand better the ecological significance of variability among plants in nectar chemistry, the effectiveness of ant attraction by different extrafloral nectars was compared for nectar mimics that varied in either amino acid or sugar content. Workers of the fire ants Solenopsis invicta Buren and S. geminata (F…

The Role of Extrafloral Nectar Amino Acids for the Preferences of Facultative and Obligate Ant Mutualists

It is confirmed that both AAs and sugars contribute to the taste and attractiveness of nectars and demonstrate that the responses of ants to specific nectar components depend on their life style.

Extrafloral nectaries mediate the arboreal beetle community (Coleoptera) in a Neotropical rainforest

It is demonstrated unequivocally that EF nectar is a frequently utilised food resource of many beetle adults and beetles have been a significantly underestimated visitor group, supporting the hypothesis that EFNs influence the occurrence and structure of beetle communities.

Catalpa bignonioides alters extrafloral nectar production after herbivory and attracts ant bodyguards

This study links caterpillar foraging, herbivore-induced changes in extrafloral nectar production, and the attraction of ants to vulnerable leaves and plants.


A study was conducted to know the interaction between ants, other insect visitors and extrafioral nectaries (EFNs) in selected crops at experimental farms of Faculty of agriculture, Annamalai

Floral and Extrafloral Nectars of Costa Rican Inga trees: A Comparison of their Constituents and Composition1

Differences in composition of the two types of nectar produced by a given Inga species may result from natural selection by mutualists utilizing the nectar as well as non-evolutionary influences of the abiotic and biotic environment.

Plant-Provided Food for Carnivorous Insects: Nectar as fuel for plant protectors

This chapter examines the many interactions promoted by nectar, with particular attention to its role in support of predatory insects on plants.

Sugar and amino acid composition of ant‐attended nectar and honeydew sources from an Australian rainforest

Comparing carbohydrates and amino acids from a representative spectrum of liquid sources used by ants in the canopy and understorey of a tropical rainforest in northern Queensland, Australia suggests variability in amino acids and carbohydrates is proposed to play a key role in ant preferences and nutrition.

Characterization and functional ecology of the extrafloral nectar of Cedrela odorata in contrasting growth environments in central Veracruz, Mexico

The results show that water has a significant influence on EFN quality and environmental disturbance that differed at each site was associated with differences in loss of water through transpiration, which affected the levels of dissolved sugars in EFN.

Morphoanatomy of nectaries of Chamaecrista (L.) Moench sections Chamaecrista , Caliciopsis and Xerocalyx (Leguminosae: Caesalpinioideae)

Whether or not the leaf glands of species of this clade are in fact nectaries is investigated, the chemical nature of their secretion is determined and the morphoanatomical database on leaf nectary in Chamaecrista is expanded to contribute to the taxonomy and phylogeny of the genus.



Response of fire ants (Formicidae: Solenopsis invicta and S.gerninata) to artificial nectars with amino acids

Day‐to‐day variability in ant behaviour was considerable even among laboratory colonies maintained on the same diet in similar environmental conditions, suggesting that ants may favour, over evolutionary time, plants that produce nectars with high levels of amino acids.

Influence of Cotton Nectar on Red Imported Fire Ants and Other Predators

The red imported fire ant, Solenopsis invicta Buren, was found to be significantly more abundant on nectaried cotton and visited a significantly higher number of nectarIED plants.

Feeding Preferences of Flesh Flies (Sarcophaga bullata) for Sugar-only vs. Sugar-amino Acid Nectars

The discriminatory ability flies showed supports the theory that flies have favored the incorporation of amino acids into floral nectars but studies of fly preferences in nature are needed.


A series of ant exclusion experiments show that branches without ants have significantly fewer larvae removed, have significantly more leaf herbivory, and produce significantly fewer mature fruits than control branches (with ants).

Amino Acid Concentrations in Extrafloral Nectar of Impatiens Sultani Increase after Simulated Herbivory

Assessment of the effect of defoliation on sugar and amino acid concentrations in the extrafloral nectar of Impatiens sultan found that amino acid content increased dramatically in plants subjected to all three levels ofdefoliation; additional work is needed to determine if the increase in amino acids is adaptive and serves to attract more plant protectors.

A Comparison of the Amino Acid Complements of Floral and Extrafloral Nectars

Differences between extrafloral and floral nectar complements presumably relate to the function of the latter in feeding ant or wasp "guards," which may have different nutritional requirements from those of pollinators.


Extra-nuptial nectar glands, by their secretion, attracts to the plants which bear them, hordes of ants which constitute a temporary and changing bodyguard, disputing the presence of all other insects with the exception of their proteges the sugar-secreting aphids, coccids, etc, and resisting often furiously and effectively, the onslaught of ruminants and other large animals.

Amino-acids in Nectar and their Evolutionary Significance

Unusual feeding-behaviour is shown by butterflies of the genus Heliconius which collect pollen, steep it in nectar, and subsequently ingest the amino-acids that diffuse from the grains.

The flow of food in colonies of the fire ant, Solenopsis invicta: a multifactorial study

The amount of food consumed by foragers was influenced by the interaction of food‐type and starvation, and the probability of the queen's receiving food increased when the labelled food was widely exchanged among her nestmates.

Feeding Acceptability of Certain Insects and Various Water-Soluble Compounds to Two Varieties of the Imported Fire Ant

Two varieties of the imported fire ant were similar in their preferences for melezitose, sucrose, and dextrose and in their rejection of xylose, ribose, mannose and galactose.
