“…Ants are known to use cuticular hydrocarbons (27,28) and aliphatic acids, albeit with different chain lengths and structures, in nest mate recognition. To our knowledge, there is only one report of a free carboxylic acid that acts as a ant trail pheromone, namely nerolic acid, found in the hindgut of Camponotus floridanus (29). P. rugosus might learn to associate prey availability with BCAAs, but this hypothesis will require additional work to place on solid experimental footing.…”

Plant glandular trichomes exude secondary metabolites with defensive functions, but these epidermal protuberances are surprisingly the first meal of Lepidopteran herbivores on Nicotiana attenuata. O-acyl sugars, the most abundant metabolite of glandular trichomes, impart a distinct volatile profile to the body and frass of larvae that feed on them. The headspace composition of Manduca sexta larvae is dominated by the branched chain aliphatic acids hydrolyzed from ingested O-acyl sugars, which waxes and wanes rapidly with trichome ingestion. In native habitats a ground-hunting predator, the omnivorous ant Pogonomyrmex rugosus, but not the big-eyed bug Geocoris spp., use these volatile aliphatic acids to locate their prey.indirect defenses | dangerous body odors

“…However, other glandular sources of trail pheromone originating in the metasoma (hindgut, pygidial gland, post-pygidial gland) or legs (tibial glands, footprint glands on the hind pre-tarsi) are also known (Morgan 2009). The Dufour's gland secretion can have colony specificity and species specificity, thereby ensuring fidelity of the trail (Traniello 1980, Haak et al 1996. The Dufour's gland has also been implicated as a storage site for chemicals involved in the alarm-defense system of ants, whereby the same chemicals can produce an alarm reaction among nestmates, while simultaneously acting as repellents to intruders Regnier 1971, Whitehouse andJaffe 1996).…”

The poison gland and Dufour's gland are the two glands associated with the sting apparatus in female Apocrita (Hymenoptera). While the poison gland usually functions as an integral part of the venom delivery system, the Dufour's gland has been found to differ in its function in various hymenopteran groups. Like all exocrine glands, the function of the Dufour's gland is to secrete chemicals, but the nature and function of the secretions varies in different taxa. Functions of the Dufour's gland secretions range from serving as a component of material used in nest building, larval food, and pheromones involved in communicative functions that are important for both solitary and social species. This review summarizes the different functions reported for the Dufour's gland in hymenopterans, illustrating how the Dufour's gland secretions can be adapted to give rise to various functions in response to different challenges posed by the ways of life followed by different taxa. Aspects of development, structure, chemistry and the evolution of different functions are also touched upon briefly.

“…Only recently the first chemical identifications of trail pheromones in several Camponotus species were reported (Bestmann et al 1995;U 8 bler et al 1995;Haak et al 1996). Here we present the results of our chemical and behavioral analysis of putative recruitment pheromones from the rectal bladder, poison gland and Dufour gland of Camponotus socius.…”
